CONVENTION FOR REVISING THE PHARMACOPOEIA. 375 
The authors have placed this new camphorated mixture 
in contact with various pharmaceutical preparations, to see 
if any decomposition ensued. They have stated a certain 
number, in the presence of which camphor is maintained 
in a state of perfect solution ; these are, a saline solution 
containing common salt and phosphate of soda, or an 
alkaline carbonate, a solution of muriate of morphia and 
sulphate of zinc, volatile alkali, acid liquids, and a weak 
solution of acetic, or muriatic acid. In the presence of 
water alone the mixture deposits camphor gradually in few 
days but this re-dissolves promptly by slight agitation.* —

ART. XCIV. — NATIONAL CONVENTION FOR REVISING THE 
PHARMACOPOEIA OF THE UNITED STATES. 
The Convention for revising the Pharmacopoeia, which 
met in Washington in January, 1840, adopted the following 
resolutions : 
" I. The President of this Convention shall, on the first 
day of May, 1849, issue a notice requesting the several 
incorporated State Medical Societies, the incorporated 
Medical Colleges, the incorporated Colleges of Physicians 
and Surgeons, and the incorporated Colleges of Phar- 
macy, throughout the United States, to elect a number of 
delegates, not exceeding three, to attend a general conven- 
tion to be held at Washington on the first Monday in May, 
1850. 
* Some of our physicians have prescribed a mixture of chloroform 
with oil of camphor — that obtained from the Dryobalanops cam- 
phora. This camphorous volatile oil is preferable to camphor alone 
for emulsionizing chloroform, and appears to have the medicinal 
properties of camphor, of which it is a strong solution. One part of 
chloroform, by measure, will form a perfect solution with 3 parts 
of camphor, by weight, and when the solution is rapidly effected, 
the temperature rises instead of diminishing, which indicates some 
chemical reaction. — Ed.
