GRINDELIA. 
Henkel, Alice, mentions Grinclelia robusta Nutt.., commonly known 
as grindelia and gum plant, as being a native in the States west of 
the Rocky Mountains.

Texas, and California. — Bull. Bur. Plant Ind., U. S. Dept. Agric.,

Schneider, Albert, points out that grindelia is used by the Indians

common species are G. cuneifolia , G . glutinosa , G. robusta , and G. 
squarrosa. — Merck’s Report, N. Y., 1906, v. 15, p. 95. 
Perredes, Pierre Elie Felix, records a study of the botanical char- 
acters of some Californian species of grindelia and figures and 
describes Grindelia robusta , G. camporum , and G. squarrosa . — Proc. 
Am. Pharm. Ass., 1906, v. 54, pp. 370-374. 
GUAIACOL. 
Francis, John M., asks why are not the sodium sulphonates of 
creosote and guaiacol as worthy of official recognition as the carbon- 
ate; he thinks thev possess many advantages. — Bull. Pharm., Detroit, 
1906, v. 20, p. 5l/ 
Graham, Willard, reports that five samples of guaiacol examined 
showed the following results: Specific gravity, 25° C., 1.12 to 1.13; 
boiling point, 199° to 205° C. All of the samples were abnormal 
according to the original U. S. P. VIII test with sodium hydrox- 
ide. — Proc. Pennsylvania Pharm. Ass., 1906, p. 153. 
Ohliger, Willard, reports that guaiacol sometimes contains 50 per 
cent of creosote. — Proc. Michigan Pharm. Ass., 1906, p. 47. 
Van den Burg, William H., asserts that guaiacol is useful in cer- 
tain cases as an intestinal antiseptic. — Trans. Am. Inst. Homceop., 
Phila., 1906, 62d sess., p. 397. 
Bryant, H. W. (Australas. Med. Gaz., Dec. 20), treated 200 cases 
of typhoid fever with guaiacol inunctions, with only one death. The

more comfortable; diarrhoea is rare. — J. Am. M. Ass., 1907, v. 48,
