PHARMACEUTICAL MEETINGS. 
MINUTES OF THE PHARMACEUTICAL MEETINGS. 
October 2d, 1843. 
Professor Carson in the Chair. 
The minutes of the previous meeting were read and 
adopted. 
Augustine Duhamel called the attention of the members 
to a root found intermixed with senega, in the proportion of 
one-third, presenting characteristics different from those of 
that drug, and easily distinguishable from it. As the subject 
possessed some interest, it was referred, for consideration, to 
Augustine Duhamel and William Procter, Jr. 
Joseph C. Turnpenny exhibited a reddish brown ferrugi- 
nous powder, deposited from a spring in New Jersey, near 
the Delaware water gap, together with some of the spring 
water. The latter has acquired a local celebrity as a remedy 
in diseases of the bladder. The hasty examination to 
which it had been submitted elicited nothing of interest in 
its composition. 
A specimen of the reticulated inner bark of the lace tree, 
and one of very old oil of lemons,were presented by the same. 
The color of the oil was reddish brown, consistence thick 
and oily, odor terebinthinate, and taste disagreeable, little 
resembling oil of lemon. It was supposed to have been 
adulterated with copaiba, but the probability is greater that 
mere age was the cause of its present condition. 
Prof. Carson informed the meeting that there was in the 
market a volatile oil, called "oil of cedar,'' and inquired if 
the source of it was known to druggists. It is stated to 
have been productive of poisonous effects when taken in- 
ternally.
