with ether: aspidium, 6.51 per cent; capsicum, 19.5 per cent; cubebs, 
21.26 per cent; lupulin, 60.59 per cent; pepper, 7.89 per cent, and ginger,

Oleoresin of Male Fern. 
Am. Jonrn. Pharm., 61, p. 169. [Proc. A. Ph. A., 37, p. 
379.] 
The sediment deposited by the ethereal oil of male fern was found by 
actual test to be as active as the supernatant oil; experiment is thus said 
to help out the statement (U. S. P. 1880) that the granular deposit should 
be thoroughly mixed with the liquid portion before being used.

Oleum Peponis. 
Am. Jour. Pharm., 62, p. 274. [Proc. A. Ph. A., 38, p. 323.] 
The pumpkin seeds comminuted with pumice stone are directed to be 
extracted with ether. Such a preparation is stated to have proved to be 
an effective taenifuge, whereas Oleum Peponis was ineffective.

Ueber Rhizoma Pannae, Aspidium athamanticum Kunze. 
Arch. d. Pharm., 229, p. 258. 
The author found no filix acid in the ethereal extract, but a substance 
Pannasaeure having the formula C n H 14 0 4 . A fatty and volatile oil were 
also isolated. The extract was found to be as active as the extract of 
male fern in the expulsion of tape worm.
