CODEX, OR FRENCH PHARMACOPOEIA.

because it is now exclusively employed throughout the 
kingdom ; but that for acids, syrups, and saline solutions, 
Baume's areometer is retained. It would, perhaps, have 
been better, and less liable to lead to confusion in practice, had 
the same instruments been employed for all liquids, whether 
heavier or lighter than water. 
So far we have scarcely done more than to present an ana- 
lysis or outline of the Codex, which would enable the 
American pharmaceutist to form some idea of the nature of 
the work which has resulted from the combined labors of its 
eminent authors, and which is required, by the laws of the 
French nation, to be invariably observed in its nomenclature 
and directions, by all French pharmaceutists and physicians. 
It cannot but be gratifying to the French pharmaceutists, 
while thus restricted in the exercise of their profession to the 
mandates of the Codex, to know that they themselves have 
contributed to its formation; and that they, so far from being 
despotically governed by laws not of their own creation, are 
really the legislators by whom the edict has been framed. 
We trust that, in the next Convention which may assemble 
for the revision of our own National Pharmacopoeia, all our 
Schools of Pharmacy will be invited to assist, from the in- 
telligence and experience of whose representatives many 
valuable practical precepts may be derived. Many excellent 
consequences, we are satisfied, would result from such a par- 
ticipation, which at present we cannot enumerate, to which 
we may, perhaps, at a future period, call the attention of the 
readers of this Journal. 
At present we must hasten to bring this lengthened notice 
to a close. It has already reached such a length as to prevent 
our being able to make any comment whatever upon the 
character of the processes of the Codex, or to compare them 
with those of our own Pharmacopoeia. This we propose to do 
at some future time, when we may, perhaps, have it in our 
power to convey to the readers of the Journal some new or im- 
proved means of conducting processes or manipulating formulae. 
The Codex has, in this article, been shown to possess the
