Gane, E. H., suggests that a concerted attempt be made to dis-

CANTHARIS. 
Hankey, William T., believes that the Chinese cantharides is more 
efficient than the more expensive Russian variety ; also that a reliable 
assay method would be a desirable addition to the pharmacopoeia. —

Philipp Roder, Wien, reports that the ash content of 5 samples of 
cantharides varied from 5.56 to 19.50 per cent. Only 2 of the sam- 
ples came within the Ph. Austr. VIII limit of 8 per cent of ash. —

Naylor, W. A. H., in a presidential address, B. P. C., reviews the 
several methods suggested by Greenish and Wilson and Dieterich for 
the estimation of cantharidin in cantharides. The several methods 
appear to give concordant results, and it is proposed that the require- 
ments be fixed at 0.60 per cent. Pie points out that there is consid- 
erable variation in the commercial articles. — Yearbook of Pharmacy, 
1906, p. 208. (See also Pharm. J., Bond., 1906, v. 23, p. 74.) 
The Ph. Brit. Committee of Reference in Pharmacy recommends 
that cantharides be assayed to contain 0.5 per cent total cantharidin.
