MINUTES OF THE PHARMACEUTICAL MEETINGS. 
agents. Specimens of most of these compounds were pre- 
sented for the examination of the members. 
Professor Bridges exhibited specimens of several species .of 
Aristolochia, particularly the reticulata of Nuttall, with a 
sample of its roots; and accompanied them with some re- 
marks on the botanical differences which distinguish them. 
The root of the A. reticulata had been recently introduced 
into this market, and sold for Serpentaria. It appears in no 
way inferior to the latter in medicinal power — the root is 
larger, and the taste more pungent. Its origin appears to be 
the neighborhood of Red river, and was received via New 
Orleans. 
A specimen of the volatile oil of the Asarum Canadense 
was presented to the meeting by Mr. Procter. 
Professor Carson exhibited the ripe fruit of the Zamia in- 
tegrifolia, the plant which yields the Florida arrow root, and 
which, together with its product, he had spoken of at length 
on a former occasion. 
A specimen of Bark, of doubtful origin, was laid on the 
table; it had some of the external characteristics of Huanuco 
Bark, with but little bitterness, and was evidently a very in- 
ferior article. 
There being no further business the meeting adjourned.

penny.
