GOSSYPIUM. 
Eberle, E. G., mentions Gossypium harbaceum among the medicinal 
plants of Texas. — Proc. Am. Pharm. Ass., 1905, v. 53, p. 304. 
Just’s Botanischer Jahresbericht (for 1905, v. 33, pt. 3, pp. 759-768) 
contains upward of 140 references on the cultivation of cotton, the 
diseases and insects attacking the plant, and various methods for 
determining the value of cotton. 
GRANATUM. 
Eberle, E. G., mentions Punica granatum among the medicinal 
plants of Texas. — Proc. Am. Pharm. Ass., 1905, v. 53, p. 304. 
Dohme, A. R. L ., believes that the alkaloid content of pomegranate 
root varies but little. For five years, 1899 to 1903, the highest aver- 
age reported was in 1900, 0.7 per cent, while the lowest, 1903, was 
0.48 per cent. — -Apothecary, Boston, 1905, v. 17, p. 942. 
Lloyd, John Uri, asserts that the rind of the fruit and the bark of 
the tree, as well as the bark of the root have all been distributed 
under the name Pomegranate bark, for which the root bark alone 
should be used. He questions if drug dealers make any efforts what- 
ever to differentiate between the bark of the different varieties of 
pomegranate, or whether it be obtained from the wild or the culti- 
vated tree. — Pharm. Rev., 1905, v. 23, p. 329. 
Caeser and Loretz outline a method for the titrimetric as well as 
the gravimetric determination of the alkaloids present in pome- 
granate root bark. — Geschafts-Ber. von Caeser & Loretz, in Halle 
a. S., 1905, pp. 81-83. 
GRINDELIA. 
Eberle, E. G., mentions Grindelia squarrosa among the medicinal 
plants of Texas. — Proc. Am. Pharm. Ass., 1905, v. 53, p. 304. 
Power and Tutin present an exhaustive paper on the chemistry of 
Grindelia robusta. The authors conclude from their work that (1) 
the chief constituents of grindelia are amorphous resins, to which its 
medicinal value is probably to be attributed; (2) Grindelia contains ( 
a considerable amount of a lse vo-rotatory sugar, apparently 1-glucose ; 
it also contains proteid substances, amorphous coloring matter and 
tannin, and an exceedingly small amount of an essential oil, possess- j 
ing the characteristic odor of the drug; (3) they are unable to con- 
firm the observations of previous investigators respecting the presence 
of a saponin or alkaloid. — Proc. Am. Pharm. Ass., 1905, v. 53, pp. 
192-201. 
Lloyd, John Uri, asserts that the shades of difference that separate 
Grindelia robusta and Grindelia squarrosa are so slight as to be 
scarcely a factor with commercial drug collectors. He also points
