and hasten its deposition. 5. The bearing of these facts upon other fields is 
pointed out. 6. Directions for procedure are given for several special cases of 
nephelometry. — Am. Chein. J., 1906, v. 35, pp. 99-114. 
He adds, as a correction, that as far as time effects in nephelometry 
are concerned, the time factor must be carefully regulated for intense 
opalescences, but ceases to be a major variable with weak ones. — Ibid., 
p. 509. 
Richards, Theodore William, adds a word of caution concerning 
the use of the nephelometer. — Ibid., pp. 510-513. 
Caspari, Chas. E., reports 10 samples examined: 9 U. S. P. ; 1 
contained lead. — Proc. Missouri Pharm. Ass., 1900, p. 99. 
Patch, E. L., reports finding silver nitrate containing trace of 
lead. — Proc. Am. Pharm. Ass., 1900, v. 51, p. 310. 
Ronde asserts that perfectly white sticks of molded silver nitrate 
may be secured by keeping the melted silver nitrate slightly acid. 
For toughening the molded silver nitrate he prefers adding from 2 
to 3 per cent of potassium nitrate, which, he asserts, will be quite 
sufficient to allow of the formation of very slender sticks that do not 
break readily. — Pharm. Ztg., Perl., 1900, v. 51, p. 1020. 
Penn, B. S., suggests a packet of aseptic materials for the care of 
the navel and eyes of the new-born child. This packet includes silver 
nitrate, boric acid, bichloride tablets, gauze, and other materials. — 
J. Am. M. Ass., 1900, v. 47, p. 1830. 
Leopold, Ch. G., (Munch, med. Wchnschr., 1900, Xo. 18, p. 849) 
attributes the occurrence of marked secondary effects to the improper 
execution of Crede’s prophylactic method, he has also observed slight 
inflammation to follow the use of the 2 per cent silver nitrate solution. 
He used a 1 per cent solution and found that with sufficient care and 
conscientious use it was possible to prevent infection. — Merck’s Ann. 
Rep. 1906, v. 20 (Darmstadt, May, 1907), p. 41. 
Lewis, F. Park, pleads for the use of light proof, hermetically 
sealed tubes for silver salts and the use of the silver salts to protect 
the eyesmf the new-born. — J. Am. M. Ass., 1906, v. 46, p. 1262. 
DeRossi, G., (Rivista d'igine e Sanita publica, v. 17, pp. 6-19, 
38-56) asserts that the silver ion, even in very dilute solutions, is 
actively toxic to microbes. He reports a number of experiments to 
show the value of silver salts, particularly the fluoride and nitrate, as 
germicides. — Jahresb. ii Tier. Chem., for 1906, 1907, v. 36, p. 865. 
An editorial quotes Kraus, (Wien. Med. Wchnschr., 1906, Xo. 1, 
Berl. Klin. Wchnschr., July 16) in which a simple clinical method 
of treating gastric ulcer is outlined, the essential medicinal agent em- 
ployed being silver nitrate, together with olive oil and sodium bicar- 
bonate. — X. York M. J., 1906, v. 84, p. 345. 
Baibakoff, A. A., (from Arch. f. Verdauungs-Ivrankheiten, Boas’, 
Berl., XII, 1) reports a series of observations on the action of silver
