ART. XL. — REMARKS ON SOAP LINIMENT. 
By Augustine Duhamel. 
C Read at the Pharmaceutical Meeting of the College^ May 1, 1843. J 
In accordance with the observations expressed by me at 
one of the late Pharmaceutical meetings, in relation to the 
congelation of the soap in our officinal Camphorated Tinc- 
ture of Soap, when prepared with rectified alcohol, I submit 
with the accompanying notice, two specimens for the con- 
sideration of my colleagues, with the view to determine the 
most approved formula. 
No. 1. — Is a specimen of soap liniment, made from cas- 
tile soap and rectified alcohol in strict conformity with the 
directions of the U.S. Pharmacopoeia of the present edition, 
and which is identical with that of the late edition. It is 
now about four months since it was made, and is filled with 
coagulum. 
To avoid the danger that might ensue from careless diges- 
tion of the soap in alcohol, the practice more generally pur- 
sued is that of allowing time to effect a spontaneous solution 
of the soap. 
No. 2. — Is a specimen of liquid opodeldoc, made agreeable 
to the following directions, and is similar to the one propos- 
ed by the Committee of Revision, when occupied with the 
subject of the Pharmacopoeia, with but the slight difference 
in the proportion of water, which is here diminished. It 
is made in the readiest manner.
