crystallization in place of 19 per cent as described. — Abstr. in Proc. 
Am. Phar. Ass., 1905, v. 53, p. 804 (from Pharm. J., London, 1905). 
LOBELIA. 
Lloyd, John Uri, points out that lobelia is likely to be contami- 
nated with other herbaceous plants. The seed, he asserts, has been 
in some cases altogether substituted by the seed of mullein which, to 
the eye, it very nearly resembles, the compound microscope being 
necessary to differentiate between them. — Pharm. Rev., 1905, v. 23, 
p. 331. 
True, Rodney H., reports that Lobelia inflata is grown regularly 
in the testing gardens of the Bureau of Plant Industry of the U. S. 
Dept, of Agriculture. — Proc. Am. Pharm. Ass., 1905, v. 53, p. 275. 
The Bureau of Plant Industry suggests planting the seed of 
lobelia in the autumn.— Ann. Rep. U. S. Dept. Agric., 1905, p. 147. 
Havenhill, L. D., found one sample of powdered lobelia which 
contained 9.3 per cent of moisture and 12.6 per cent of ash. Nearly 
one-lialf, or 5.8 per cent, of the ash was sand. — Proc. Kansas Pharm. 
Ass., 1905, p. 92. 
Yanderkleed, Charles E., reports 3 assays of lobelia, which varied 
from 0.72 to 1.48 per cent of alkaloid, the average standard for good 
drug being 5.0 per cent. — Proc. Pennsylvania Pharm. Ass., 1905, 
p. 56. 
An editorial points out that while the change from hydro-alcoholic 
to an acetic acid menstruum may be of advantage in connection with 
the fluid extract of squill and the fluid extract of sanguinaria, the 
change is doubtful in connection with fluid extract of lobelia. — Drug 
Topics, 1905, v. 20, p. 194. 
LUPULINUM. 
Moore, Russell W., points out that the indirect method of determin- 
ing the quality of lupulin by means of the ash was held to be less 
satisfactory than a direct estimation of the valuable or ether soluble 
portion. Of 25 samples examined only 2 contained less than the 
standard of 10 per cent of ash, while 12 w T ere above the minimum of 
70 per cent of ether extract. The ash allowance of the Ph. Brit., IV, 
15 per cent, appears to be entirely compatible with the 70 per cent of 
ether extract of the U. S. P., VIII. — Proc. Am. Pharm. Ass., 1905, 
v. 53, p. 267. 
The revisors of Vienna pharmacies found lupulin which contained 
from 7.42 to 28.22 per cent of ash and point out that an ash content 
of more than 10 per cent is objectionable. — Pharm. Prax., 1905, v. 4, 
p. 38.
