PHARMACY. 



different densities should be disused, and 

 the measure received into the shops of 

 apothecaries, a point upon which it will 

 be necessary to place especial stress, in 

 order that prescriptions may be accurate- 

 ly prepared. As the same Latin term has 

 been employed to express the pint mea- 

 sure and the pound weight, they have 

 extended the same resemblance to in- 

 ferior measures, and have the more rea- 

 dily substituted granum for gutla, because 

 the latter term implies that peculiar 

 mode of division which they wish to de- 

 precate. 



3. Jlmangement. On this head it is only 

 necessary to observe, that the chapters 

 have been arranged in what appeared to 

 be a more natural and convenient order 

 of the substances concerned than the 

 former one. 



4. Processes. Considerable alteration 

 has been made in various processes, by 

 which it is hoped they will be found more 

 accommodated to general use. Expense 

 in preparation ought not to be balanced 

 against correctness and uniformity, and it 

 is to be lamented that the profits and 

 competition of trade should have induced 

 a very extensive disposition to deviate 

 from the directions of the Pharmacopoeia. 

 To this point, therefore, the Committee 

 have looked with much attention, and, as 

 far as they have thought themselves 

 justified they have endeavoured to make 

 such deviation less an object to the ope- 

 rating chemist than heretofore ; for this 

 purpose they have not looked in their 

 formulae to that accuracy which would be 

 necessary for chemical' tests, but rather 

 to the uniformity of the preparation, and 

 its use as a medicine. The directions 

 for manipulation are given generally, be- 

 cause they admit of some variety in their 

 application in many instances, according 

 to the scale on which they are prepared, 

 and other circumstances; the Committee 

 trust, however, that, if their directions be 

 followed, the results will be in the same 

 proportion uniform and correct, and that 

 the well educated apothecary will have 

 no difficulty in understanding and apply- 

 ing them. "Under this head, it is particu- 

 larly incumbent upon the Committee to 

 acknowledge the great advantage they 

 have derived from the liberal communica- 

 tions of the Society of Apothecaries, 

 with respect to the practice of their ex- 

 tensive concern, and also from many indi- 

 viduals engaged in chemical preparations 

 upon a large scale. 



5. Omission of fanner Articles, and Tn- 

 troduction of ne\v ones. In the rejection 



of many substances of trifling importance 

 or efficacy, of others which have ap- 

 peared rather to belong to extemporane- 

 ous prescription, and of certain forms of 

 medicine which have become obsolete in 

 general practice, and also in the intro- 

 duction of any new articles, the Com- 

 mittee have exercised their own judg- 

 ment freely, and they trust with sufficient 

 caution. They hope the College at large 

 will approve of their having neglected to 

 insert many substances which individual 

 practitioners have recommended and 

 employed, where such have not received 

 the sanction of more general experience. 

 They conceive further, that a strict ex- 

 amination of its powers ought to precede 

 the introduction of any article into the 

 Pharmacopoeia, and that the late appoint- 

 ment of a Committee of the College for 

 this express purpose will hereafter ap- 

 preciate the value of such recommenda- 

 tions by surer tests than those which have 

 heretofore been deemed sufficient. 



The proposed Materia Medica is as 

 follows, in which it will be perceived that 

 the vegetables are described, in the 

 second column, from Wildenow's edition 

 of the " Species Plantarum" of Linnzeus ; 

 and the animals from Gmelin's " Systema 

 Naturae" of the same writer, excepting 

 indeed in a very few instances. This table 

 we cannot and ought not to abridge.
