EXTRACTS FROM THE MINUTES OF THE PHARMACEUTICAL 
MEETINGS. 
October 6th, 1S45. 
Charles Ellis, Vice President, in the Chair. 
The minutes of the preceding meeting were approved. 
There being no written communications, Samuel C. 
Sheppard called the attention of the meeting to some speci- 
mens of blue mass, numbered 1,2, 3, 4, and 5. The first 
was manufactured by George W. Ridgeway of this city, 
the rest of various origin and quality. With a view to their 
analysis the specimens were referred to Ambrose Smith, 
J3r. Robert Bridges, and Samuel C. Sheppard, as a com- 
mittee. 
Dillwyn Parrish called the attention of the meeting to a 
specimen of Bittern, from the salt works of western Penn- 
sylvania, from those springs containing Bromine. This Bit- 
tern, or mother water, resulting after the separation of the 
salt, is a dark coloured liquid, sp. gr. 1.419. 
A specimen of bromide of iron was also presented. 
Joseph C. Turnpenny remarked that, in mixing hydrarg. 
cum creta with inspissated ox-gall, the mercury was noticed 
to separate in considerable quantity without any moisture 
being added. Another member had observed the same 
phenomenon when extract of rhubarb was incorporated 
with the same preparation. The mercurial preparation 
was of good quality. 
William Procter, Jr., exhibited specimens of extract of 
stramonium, with and without the chlorophylle. The latter 
was dark colored, and highly efficient. 
The same member presented a sample of an article of 
opium, which had been sold in this city at Comly's auction 
store, at a third of the market pr^ce. It had the aspect of 
exhausted opium, and was made up into globular and com- 
pressed masses. The subject was referred to W. Procter, 
Jr,. J. H. Ecky, and J. C. Turnpenny, for examination.
