neric appellation, and all their binary combinations under 
another, so that almost every chemical reagent, whether 
simple or compound, would be a salt or a radical. 
100. Before concluding, I feel it to be due to the cele- 
brated German chemist above mentioned, to add, that how- 
ever I may differ from him as to the acids being hydrurets 
of compound radicals, I am fully disposed to make acknow- 
ledgments for the light thrown by his analytical researches 
on organic chemistry, and the successful effect of his inge- 
nious theoretic speculations, in rendering that science more 
an object of study with physicians and agriculturists. 
ART. L ON THE MODE OF PREPARATION AND 
THERAPEUTIC PROPERTIES OF ERGOTINE. 
By M. Bonjean. 
Powdered ergotized rye is treated with water in a dis- 
placement apparatus, and the aqueous solution heated over a 
water bath. By the action of the heat, this solution some- 
times coagulates from the presence of a certain quantity of 
albumen; sometimes not. In the former case, the coagulum 
is separated by filtration; the liquid evaporated, over a water 
bath, to the consistence of a clear syrup, to which a large 
excess of alcohol is then added, which precipitates all the 
gummy substances; the liquid is then placed aside until all 
the gum has subsided, and the solution has reassumed its 
transparence and brightness, when it is decanted and reduc- 
ed, over a water bath, to the consistence of a soft extract. 
In the second case, the aqueous solution is brought imme- 
diately to a semi-syrupy state, and then treated, as above, 
with alcohol, in order to obtain the extract
