Analysis. 
With a view of ascertaining the chemical constituents of 
this root, the following experiments were made. 
Experiment First. — A decoction was made by boiling 
one ounce of the bruised root in a pint of water. This was not 
discolored by animal charcoal, but was of a deep brown color, 
astringent taste, and had an acid reaction with litmus. With 
this decoction, solution of gelatin produced a copious curdy 
precipitate, muriate of iron a deep blue, and sulphuric acid a 
whitish precipitate ; by the addition of a solution of the sul- 
phate of morphia, a beautiful white tannate of morphia was 
thrown down. On the addition of alcohol, a coagulum was 
produced, and nitrate of silver separated a precipitate. Sub- 
acetate of lead being added, a whitish precipitate was thrown 
down, which was reddened by nitric acid. Tested with 
tincture of iodine, it failed to produce the blue color, indica- 
tive of the presence of starch. Precipitation by the sub- 
acetate of lead deprived the decoction of color. 
Experiment Second. — The cold infusion made by the dis- 
placement process, produced a whiteprecipitate with corrosive 
sublimate, and upon the application of heat a coagulum was 
formed. Both this infusion and that made by the ordinary 
method of maceration, possessed the sensible properties of the 
decoction, in a dilute state, and both afforded evidences of 
vegetable albumen. 
Experiment Third. — A portion of the decoction was di- 
gested for twenty-four hours, with hydrate of alumina, filter- 
ed and tested for gallic acid. It produced slight precipitates, 
with tincture of muriate of iron and lime water, but which I 
am induced to believe, since depriving the root more tho- 
roughly of tannic acid by the process of experiment fourth, 
were occasioned by traces of that acid remaining in the solu- 
tion, or probably oxidized by boiling in contact with the air. 
Experiment Fourth. — One hundred grains of the powder- 
ed root were boiled with successive portions of water, until 
the soluble parts were entirely dissolved; these were then
