Scientific American Volume 22, No. 1, January 1, 1870 Part 8

"Strange as it may at first seem, the war on geology was waged more fiercely in Protestant countries than Catholic, and of all countries England furnished the most bitter opponents. You have noted already that there are generally two sorts of attacks on a new science. First, there is the attack by pitting against science some great doctrine in theology. You saw this in astronomy, when Bellarmine and others insisted that the doctrine of the earth's revolving about the sun is contrary to the doctrine of the Incarnation. So now against geology it was urged that the scientific doctrine that the fossils represented animals which died before Adam was contrary to the doctrine of Adam's fall, and that death entered the world by sin. Then there is the attack by the literal interpretation of texts, which serves a better purpose generally in arousing prejudice. It is difficult to realize it now, but within the memory of the majority of those before me, the battle was raging most fiercely in England, and both these kinds of artillery were in full play and filling the civilized world with their roar. Less than thirty years ago, the Rev. J. Mellor Brown was hurling at all geologists alike, and especially at such Christian divines as Dr. Burkland, Dean Conybeare, and Pye Smith, and such religious scholars as Professor Sedgwick, the epithets of 'Infidel,' 'Impugner of the Sacred Record,' and 'a.s.sailant of the Volume of G.o.d.' His favorite weapon was the charge that these men were 'attacking the Truth of G.o.d,' forgetting that they were simply opposing the mistaken interpretations of J. Mellor Brown. He declared geology 'not a subject of lawful inquiry;' he speaks of it as 'a dark art,' as 'dangerous and disreputable,' as a 'forbidden province.' This attempt to scare men from science having failed, various other means were taken.

"To say nothing about England, it is humiliating to human nature to remember the trials to which the pettiest and narrowest of men subjected such Christian scholars in our country as Benjamin Silliman and Edward Hitchc.o.c.k. But it is a duty and a pleasure to state here that one great Christian scholar did honor to religion and to himself by standing up for the claims of science despite all these clamors. That man was Nicholas Wiseman, better known afterward as Cardinal Wiseman. The conduct of this pillar of the Roman Catholic Church contrasts n.o.bly with that of timid Protestants who were filling England with shrieks and denunciations. Perhaps the most singular attempt against geology was that made by a fine specimen of the English Don, Dean c.o.c.kburn of York, to _abuse_ its champions out of the field. Without apparently the simplest elementary knowledge of geology, he opened a battery of abuse.

He gives it to the world at large by pulpit and press; he even inflicts it upon leading statesmen by private letters. But these weapons did not succeed. They were like Chinese gongs and dragon lanterns against rifled cannon. Buckland, Pye Smith, Lyell, Silliman, Hitchc.o.c.k, Murchison, Aga.s.siz, Dana, and a host of of n.o.ble champions besides, pressed on the battle for truth was won. And was it won merely for men of science?

The whole civilized world declares that it was won for religion; that thereby has infinitely increased the knowledge of the power and goodness of G.o.d."

The lecturer cla.s.sed the present opposition of the Catholics to the Free School system in this country among the long list of battles between science and theology and concluded his lecture as follows:

"But, my friends, I will not weary you with so recent a chapter in the history of the great warfare extending through the centuries. There are cheering omens. The greatest and best men in the churches--the men standing at centers of thought--are insisting with power, more and more, that religion shall no longer be tied to so injurious a policy--that searchers for truth, whether in Theology or Natural Science, shall work on as friends, sure that, no matter how much at variance they may at times seem to be, the truths they reach shall finally be fused into each other. No one need fear the result. No matter whether science shall complete her demonstration that man has been on the earth six thousand years or six hundred thousand. No matter whether she reveal new ideas of the Creator or startling relations between his creatures--the result, when fully thought out, will serve and strengthen religion not less than science. The very finger of the Almighty has written on history that science must be studied by means proper to itself, and in no other way.

That history is before us all. No one can gainsay it. It is decisive, for it is this: There has never been a scientific theory framed for the use of Scriptural texts, which has been made to stand. This fact alone shows that our wonderful volume of sacred literature was not given for any such purpose as that to which so many earnest men have endeavored to wrest it. The power of that volume has been mighty indeed. It has inspired the best deeds our world has known. Despite the crusts which men have formed about it--despite the fetters which they have placed upon it--Christianity has blessed age after age of the past, and will go on as a blessing through age after age of the future. Let the Warfare of Science, then, be changed. Let it be a warfare in which religion and science shall stand together as allies, not against each other as enemies. Let the fight be for truth of every kind against falsehood of every kind--for justice against injustice--for right against wrong--for beauty against deformity--for goodness against vice--and the great warfare which has brought so many sufferings, shall bring to the earth G.o.d's richest blessings."

HOW FRENCH BANK NOTES ARE MADE.

When a new batch of French notes is to be printed, an equivalent number of the choicely prepared and preserved sheets of paper is handed over to the superintendent of the printing office. This office is among the inner buildings of the Bank of France, and is governed by very rigorous rules in all things. The operatives are all picked men, skillful, active, and silent. The sheets, the ink, and the matrixes of the plates are kept securely under lock and key until actually wanted. The printing is effected by steam-worked presses. The ink is blue, and its composition known only to a few of the authorities. An inspector goes his rounds during the continuance of the operations, watching every press, every workman, every process. A beautiful machine, distinct from the press, is employed to print the variable numbers on the note; fed with sheets of paper, it will number a thousand of them in succession, changing the digits each time, and scarcely requiring to be touched meanwhile; even the removal of one note and the placing of another are effected by automatic agency. At every successive stage the note is examined. So complete is the registration of everything that a record is always at hand of the number of sheets rejected ever since the Bank of France was established, be its defects in the paper, the printing, or the numbering. When the master-printer has delivered up his packets of printed and numbered sheets, each note is stamped with the signature of the Secretary-General and the Comptroller. This completes the _creation_ of notes. The notes so created are kept in a strong box, of which the Secretary-General and the Comptroller have keys, and are retained until the day of _issue_. The chief cas.h.i.+er tells the Governor that he wants a new supply of a particular denomination of notes, the Governor tells the council, the council tell the secretary-general and the comptroller, and these two functionaries open their strong box, and hand over the notes demanded. The notes at this time are not really money; they do not become so until the chief cas.h.i.+er has put his signature to each, and registered its number in a book.

The life of a French bank note is said to average two or three years, and does not terminate until the condition is very shaky indeed--crimpled, pierced with pinholes, corner creases torn, soft, tarnished, decrepit while yet young. Some have been half-burned; one has been found half-digested in the stomach of a goat, and one boiled in a waistcoat-pocket by a laundress. No matter; the cas.h.i.+er at the bank will do his best to decipher it; he will indeed take an infinity of trouble to put together the ashes of a burned note, and will give the owner a new note or the value in coin, if satisfied of the integrity of the old one. The bank authorities preserve specimens of this kind as curiosities, minute fragments gummed in their proper position on a sheet of paper. Very few of the notes are actually and irrevocably lost.

During the last sixty-seven years 24,000 bank notes of 1,000 francs each have been issued, and of this number 23,958 had been returned to the bank by the month of January 1869, leaving only 42 unaccounted for.

Whether these 42 are still in existence, or have seen burned into uncollected ashes, or are at the bottom of the sea, or elsewhere, is not known. Of 500-franc notes, 24,935 have been returned out of 25,000. The bank holds itself morally and financially responsible for the small number of notes unreturned, ready to cash them if at any time presented.

The bank sends the old notes again and again into circulation, if verified and usable; but they are examined first, and any that are found too defective are canceled by stamping a hole in them. These canceled notes pa.s.s from one official to another, and are grouped in cla.s.sified bundles; the book that records the birth of each note now receives a notification of its civil death, and after three years incarceration in a great oak chest, a grand conflagration takes place. A huge fire is kindled in an open court; the defunct notes are thrown into a sort of revolving wire-cage over the fire; the cage is kept rotating; and the minute fragments of ash, whirled out of the cage through the meshes, take their flight into infinite s.p.a.ce--no one knows whither. The Bank of France prints a certain number of notes per day, and destroys a smaller number, so as to have always in reserve a sufficient supply of new notes to meet any emergency; but the actual burning, the grand flare-up takes place only about once a month, when perhaps 150,000 will be burned at once. The French go down to lower denominations than the Rank of England, having notes of 100 francs and 50 francs, equivalent to 4 and 2. There must be a great deal of printing always going on in the Bank of France, seeing that in 1868 they issued 2,711 000 notes, of an aggregate value of 904,750,000 francs (averaging about 13 each), and burned 1,927,192, value 768,854,900 francs.

It _sounds_ a very dreadful thing for 30,000,000 sterling in bank notes to be willfully burned in one year. But there is always a phoenix to rise from its ashes; the bank can regenerate as fast as it kills. The Bank of France, in 1846, put in circulation a beautiful crimson printed note for 5,000 francs; but the French people did not like notes of so high a denomination, and all but a very few of this kind have been returned and canceled. On one occasion, a superb individual, wis.h.i.+ng to pay a dowry in handsome style, obtained twelve notes of 5,000 francs each for the purpose; but they were returned the very next day by the banker, who much preferred smaller notes for his general purposes. The notes now regularly kept in circulation in France are those of 1,000, 500, 100, and 50 francs.

WHAT THE NEWSPAPERS SAY.

A VALUABLE PAPER.--Of all the journals published in the United States, for the mechanic and scientific man, there is nothing that will in any way compare with the SCIENTIFIC AMERICAN, published by Munn & Co., of 37 Park Row, New York. Whether as a work of reference, a record of current scientific development, or as an organ and exponent of our inventors, it stands alone for the general ability of its conduct, the voluminousness and variety of its contents, the exact.i.tude and extent of its knowledge, and the correctness of its information. The SCIENTIFIC AMERICAN is a credit at once to the press and our country, and the small price of a yearly subscription ($3), purchases, it is quite safe to say, the largest amount of solid value to be procured for a like expenditure in the world. With our more intelligent mechanics it has long been a great favorite, while to the inventor it is absolutely indispensable. It has had many imitators and compet.i.tors in its day, but they have nearly all died the natural death of a feeble inferiority.--_Argus_ (Brooklyn, N.

Y.)

THE GREAT JOURNAL OF ARTS AND SCIENCE.--There is a place in the periodical literature of America which is occupied by only one journal; namely, the well-known SCIENTIFIC AMERICAN.

It is almost indispensable to a well-balanced intelligence, that a certain proportion of its reading should be devoted to the industrial arts and sciences, those natural manifestations of the high mental development of the age. Every number of the journal has sixteen imperial pages, embellished with engravings, as ill.u.s.trations, which are gems of art in themselves. It is most ably edited, and its usefulness is not impaired by technical terms nor dry details.--_Milwaukee Sentinel._

THE SCIENTIFIC AMERICAN.--This paper is the oldest in its peculiar province in the United States, and was, for many years, the only one.

More recently others have arisen, and are following in its footsteps; but the SCIENTIFIC AMERICAN still maintains its position as the best American journal of the inventive arts. Its Patent Office department alone is invaluable to inventors, while its editorial articles, ill.u.s.trations, etc., give not only information, but a constant stimulus to the productive faculty.--_Mobile Register_.

Among the papers which we could not very well do without is the SCIENTIFIC AMERICAN, issued from the well-known office of Munn & Co., 37 Park Row, New York. Carefully edited, nicely printed, well ill.u.s.trated, it is not only a complete record of the progress of useful inventions, but a trustworthy guide to many of the scientific topics that enlist attention at the present day. No one can be a reader of this most valuable journal, without being kept well informed as to current matters of scientific discovery.--_Congregationalist_ (Boston).

THE SCIENTIFIC AMERICAN.--In another column we publish the prospectus of this great paper, and would direct our readers to it. It should be on the work bench of every mechanic, and particularly the young men of our country, upon whose intelligence and mechanical skill depends the future dignity of labor and prosperity of American arts and sciences.--_Monitor_ (Huntington, Pa.)

We could fill our pages with similar notices, but will close with the following from our cotemporary _De Hope_, published at Holland, Mich., which we doubt not will be read with interest:

Wij plaatsen in dit Nummer het prospectus van den SCIENTIFIC AMERICAN.

Het is een zeer schoon blad, dat vooral behoort gelezen te worden door Handwerkslieden. Nieuwe uitvindingen, verbeteringen op het terrein van werktuigkunde, enz, worden daar steeds in vermeld en beschreven. De prijs is zeer matig voor zulk cen blad; drie dollars per jaar. Dat belangstellenden de advertentie lezen.

CHINESE METHODS OF PRESERVING EGGS.

As much has been said of late about the mode of preserving eggs, it may not be uninteresting to say a few words about the Chinese methods, as related by a French chemist, M. Paul Champion, who has lately visited that country, and published a very interesting book on the ancient and modern industries of that curious people. A very common method is to place the eggs in a mixture of clay and water; the clay hardens around the eggs, and is said to preserve them good for a considerable time. But another and much more elaborate method is also commonly practiced. An infusion of three pounds of tea is made in boiling water, and to this are added three pounds of quicklime (or seven pounds when the operation is performed in winter), nine pounds of sea-salt, and seven pounds of ashes of burnt oak finely powdered. This is all well mixed together into a smooth paste by means of a wooden spatula, and then each egg is covered with it by hand, gloves being worn to prevent the corrosive action of the lime on the hands. When the eggs are all covered with the mixture, they are rolled in a ma.s.s of straw ashes, and then placed in baskets with b.a.l.l.s of rice--boiled, we presume--to keep the eggs from touching each other. About 100 to 150 eggs are placed in one basket. In about three months the whole becomes hardened into a crust, and then the eggs are sent to market; the retail price of such eggs is generally less than a penny each. These eggs are highly esteemed in China, and always served in good houses; but they have undergone a strange transformation, which certainly would not recommend them to English palates; the yolk has a.s.sumed a decidedly green tinge, and the white is set. When broken, they emit that unpleasant sulphurous smell which would certainly cause their instant banishment from our breakfast-tables. However, the Chinese are admitted, even by Frenchmen, to be great _gourmets_; and we can only say, therefore, that in questions of eating there is certainly no disputing about tastes.

STEAM BOILER INSPECTION.

Mr. Alfred Guthrie, U.S. Inspector, informs us that the following resolution was recently adopted by the Board of Supervising Inspectors:

Resolved, That a special committee be appointed, to whom shall be referred the subject-matter of steam boiler explosions, who shall be requested to take up the subject in all its varied complications, and present the result of their inquiries, with their opinions of the real causes of such explosions, accompanied by such information as may be of practical benefit and general interest, to be reported at the next annual meeting of the board for its consideration.

Mr. Guthrie, whose address will be at Was.h.i.+ngton, D.C. until January 10, desires to receive suggestions from practical engineers upon the subject of boiler explosions.

EDITORIAL SUMMARY.

Darkness of complexion has been attributed to the sun's power from the age of Solomon to this day. "Look not upon me because I am black, because the sun hath looked upon me." And there cannot be a doubt that, to a certain degree, the opinion is well founded--the invisible rays in the solar beams, which change vegetable color, and have been employed with such remarkable effect on the daguerreotype, act upon every substance on which they fall, producing mysterious and wonderful changes in their molecular state, man not excepted.
