=Mixture, Senega, with Ammonia.= (St Th. H.) _Syn._ MISTURA SENEGae c.u.m AMMONIA. _Prep._ Infusion of senega, 1 oz.; carbonate of ammonia, 4 gr.

=Mixture, Sen'na (Compound).= _Syn._ BLACK DRAUGHT, ABERNETHY'S D., CATHARTIC MIXTURE; MISTURA SENNae COMPOSITA (B. P.), L. _Prep._ 1. Infusion of senna, 3/4 pint; tincture of senna, 1-1/2 fl. oz.; Epsom salts, 4 oz.; carbonate of ammonia, 1/2 dr.; sugar, 3 oz.; agitate until the solids are dissolved.

2. Senna, 13 oz.; boiling water, 2 quarts; digest for 4 hours in a hot place, then press out the liquor in a tincture press, and add, of compound tincture of senna, 3/4 pint; Epsom salts, 1 lb.

3. East India senna, 2 lbs.; boiling water, 9 quarts; tincture of senna and Epsom salts, of each 3-1/4 lbs.; as the last.

7. (B. P.) Infusion of senna, 14; sulphate of magnesia, 4; extract of liquorice, 1/2; tincture of senna, 2-1/2; compound tincture of cardamoms, 1-1/4: dissolve and mix.--_Dose_, 1 to 1-1/2 oz.

_Obs._ As the above mixture contains very little spirit, and from its great consumption being made in large quant.i.ties at a time, it frequently spoils before the whole is sold especially in hot weather. To avoid this, 1-1/2 dr. of cloves, and 3 dr. of mustard seed, both bruised, may be added to every gall. of the strained liquor at the same time with the salts, spirit, and colouring, after which it must be shaken up repeatedly for a few days, and then allowed to repose for a few days more when it will become quite clear. It may be filtered through a flannel bag, but there is much loss and delay, owing to the consistence of the liquid. It is purgative in doses of 1 to 1-1/2 fl. oz.

It is a singular circ.u.mstance, that although an enormous quant.i.ty of this preparation is consumed in these countries, there is no standard formula for it in the British Pharmacopias. See MIXTURE, APERIENT, &c.

=MIXTURES (Arithmetic of).= The constantly recurring necessity in business and chemical manipulations of determining the value of mixtures, and of producing articles and preparations of different strengths or prices to those already in stock, has rendered a ready means of making such calculations an indispensable qualification in almost every department of trade and industrial art. As we address ourselves to the intelligent operative and busy tradesman, as well as to those more blessed by education and leisure, we feel we are bestowing a boon on many of our readers in giving a short, but sufficient, outline of this useful branch of commercial arithmetic, which is most intimately connected with the objects of the present work.

1. To determine the price of a mixture from the value and quant.i.ty of each ingredient of which it is composed.--RULE. Divide the 'gross value' by the 'gross saleable' or 'useful quant.i.ty,' the quotient is the value or cost per gallon, pound, &c., as the case may be.--_Example._ Required, the value per gallon of a hogshead of wine containing--

_s._ _d._ _s._ _d._

30 gallons @ 10 6 = 15 15 0 20 " " 12 6 = 12 10 0 13 " " 14 6 = 9 8 6 -- --------------- 63 divide into 37 13 6 --------------- Cost per gallon 0 11 11-1/2

2. To determine the proportions of substances or articles of different values or strengths which must be taken to prepare a mixture of any other value or strength.--RULE. Arrange the 'prices' or 'strengths of the ingredients' in a column, and link them together in pairs; each of those above the required price being always connected with another below it.

Then set the difference between the required price and these numbers, alternately against those they are linked to; when they will indicate the quant.i.ties to be taken, as in the following examples:--_a._ Required the proportions of tea at 3_s._, 4_s._, 6_s._, and 7_s._, that must be taken to produce a mixture 5_s._ the pound. Here--

{ 3--+ 1, or 1 lb. @ 3_s._ { 4-- --+ 2, " 2 " " 4_s._ 5 { 6--+ 2, " 2 " " 6_s._ { 7-----+ 1, " 1 " " 7_s._

_b._ (When the number of the ingredients or prices is odd.) Required the proportions of teas at 3_s._, 5_s._, and 6_s._, the pound, to sell at 4_s._ Here the odd number must be taken a second time:--

{ 3--+--+ 1 + 2 or 3 lbs @ 3_s._ 4 { 5--+ 1, " 1 " " 6_s._ { 6-----+ 1, " 1 " " 6_s._
