The above sketch will at once enable our readers to see the great changes which 
have been effected in organic substances in the British Pharmacopoeia. In 
a general glance over its pages we notice several errors, two of which, from their 
importance, we shall now allude to; thus, under the head of Oleum Crotonis, 
we find that “the Oil expressed from the seeds in England” is ordered to be 
used ; and the following is given as the test:—“Agitated with its own volume 
of alcohol, and gently heated, its forms a clear solution, from which about three- 
fourths of the oil separate on cooling.” This test is about true as regards East 
Indian Croton Oil, but it is not true with English Croton Oil, which is wholly 
and readily soluble in alcohol, and the solution thus formed is permanent at or¬ 
dinary temperatures. Under the head of Tinctura Aconiti, it is stated that 
“this tincture has half the strength of Tinctura Aconiti, Dub., and one-third 
of the strength of Tinctura Aconiti, Londf This is an error; it should be as 
followsThis tincture has one-fourth the strength of Tinctura Aconiti, Dub., 
and one-third of the strength of Tinctura Aconiti, Lond. 
In our next number we shall give critical and explanatory notes of such arti¬ 
cles of the organic materia medica as may require them. We forbear, until our 
notices are concluded, from expressing any positive opinion upon the manner 
in which this portion of the work has been executed, but at the same time we 
cannot but express our belief that it will be found the most perfect and best part 
of the British Pharmacopoeia.
