out that Gnndelia squamosa as such is not to be had on the general 
market. The demand is restricted and whoever obtains it must get 
it directly from an intelligent drug collector. — Pharm. Rev., 1905,

Cowperthwaite, A. C., points out that Grindelia robusta is used in 
asthma, bronchitis, whooping cough, and rhus poisoning, both inter- 
nally and locally. — Tr. Am. Inst. Homoeop., 1905, v. 61, p. 363. 
GTJAIACOL. 
An abstract (from J. de Pharm. d’ Anvers, 1905, No. T) suggests 
the following formula for guaiacol pills: Guaiacol 1.0, powd. glycyr- 
rhiza 1.0, potassium carbonate 0.25, glycerin a sufficient quantity. 
Mix and make into 25 pills. — Pharm. Ztg., Berlin, 1905, v. 50, p. 773. 
Opikhamoff, P. A., has published a monograph (St. Petersburg, 
1905) on the influence of guaiacol on the blood in cutaneous applica- 
tion. — Reference from Ind. Med., 1905, v. 3, p. 671. 
Hecht (Miinch. Med. TTchnschr., 1905, v. 52, p. 415) discusses the 
endermatic application of guaiacol. — Ibid ., p. 355. 
Schuller, Max, discusses the use of guaiacol in the treatment of 
tuberculosis of the kidneys. — (From Mitteilungen a. d. Grenzgebiet. 
Jena, 1905, v. 15, Nos. 1 & 2.) Abstr. in J. Am. M. Ass., 1905, v.

GUAIACUM. 
Moore, Russell W., says that of 124 samples of guaiac examined for 
entry into the port of New York, 69 were below the standard of 80 
per cent resin. The maximum was 91.4 per cent and the minimum 
61.7 per cent, the average being 77.92 per cent. — Proc. Am. Pharm. 
Ass., 1905, v. 53, p. 266. 
Petit and Meyer (Compt.-rend., 1905, v. 141, pp. 193-195) discuss 
the several reactions of guaiac and point out among other facts that 
the tincture of guaiac gives a very strong blue coloration with iron 
or manganese salts. — Abstr. in J. Chem. Soc., Lond., 1905, v. 88, 
part 2, p. 655. 
Gadd and Gadd assert that 110 minims of ammoniated tincture 
of guaiac (Ph. Brit., IY) evaporated on a water bath for three hours 
should yield a residue of not less than 15 grains. — Pharm. J., Bond., 
1905, v. 21, p. 579. 
Caldwell, Paul, suggests that in. making the ammoniated tincture 
of guaiac a more purely alcoholic menstruum be used, to which the 
oils and an equivalent amount of spirit of ammonia might be added. — 
Drug. Circ. & Chem. Gaz., N. Y., 1905, v. 49, p. 306.
