REPORT ON THE PHARMACOPEIA. 
Previously to the final action of the Committee on the 
above subjects, they took into consideration, the manner in 
which they would proceed with the revision of the second 
grand division of the Pharmacopoeia, containing the formulae 
for preparations. On the 19th of May, it was resolved that 
the consideration of the preparations be divided among sub- 
committees, whose duties shall be to examine carefully the 
existing formulae of the Pharmacopoeia, which may be referred 
to each ; to compare the proportions employed, with those 
directed in other standard Pharmacopoeias; to criticize the direc- 
tions given for preparation ; to append to each formula the equi- 
valent of troy weight in equal parts; to recommend the intro- 
duction of such new preparations as they may deem necessary; 
to be careful in the arrangement and terms of new formulae, 
in order to preserve the symmetry already existing, as well as 
in the employment of the nomenclature adopted; to indicate the 
* removal to the Materia Medica list, of such preparations as they 
may think proper; to consult, such works as are especially re- 
garded as standard; as Turner's Chemistry, London Pharmaco- 
poeia, Paris Codex, American Journal of Pharmacy, and Uni- 
versal Pharmacopoeia; and finally to seek the best information 
from every source, confirming doubtful opinionsby experiment, 
and assigning reasons for every alteration and removal. Every 
member of the Committee of Revision, being expected to 
furnish to the sub-committee, of which he is not a member, 
any information or suggestion, in regard to subjects especially 
referred, which he might possess. Under this resolution the 
Committee was divided into three standing sub-committees 
on the preparations, which were distinguished as No. 1, No. 2 
and No. 3. 
Com. No. 1 consisted of Messrs. Ellis, Powers, and Smith. 
" 2 " " Durand, Moore, and Procter. 
" 4 " " Fisher, Allen, and Duhamel. 
The above resolution, in its various branches, comprises in 
a compendious form all the principles by which the Com-
