mula of the Ph. Germ. Many of the preparations of this class which 
produce milky solutions are made from the crude oil from which 
phenol has been separated ; the milkiness he attributes to the presence 
of naphthalene. — Ibicl., v. 78, pp. 100, 101. 
La Wall and Cook's paper appears. (Ibid., pp. 169-172.) They 
think the amount of soap used in the official solution needlessly large : 
two-thirds of the amount directed has given equally satisfactory 
results. They caution against the application of heat after the addi- 
tion of the cresol, as it is quite volatile and the vapor is inflammable. 
Thrush, M. Clayton, thinks it should have been prescribed that the 
compound solution of cresol be allowed to stand for at least two weeks 
after making, or that it should be prepared by heating, in order to 
complete the saponification; otherwise the free cresol present makes 
it too irritating. — Ibid., v. 78, p. 33. 
Caldwell, Paul, points out that the pharmacopoeia directs compound 
solution of cresol to be made by adding the cresol before the soap is 
formed. He believes the better way is to add it afterwards, as in 
such case a clear solution results at once. He also advises the addi- 
tion of 5 per cent of glycerin, so as to make the solution miscible with 
water to any extent. — Drug. Circ. & Chem. Gaz., X. Y., 1906, v. 50, 
p. 159. 
A resin soap to be used in making a saponaceous emulsion of cresol 
may be prepared by using soda lye, 30° B., 1 gallon: pulverized rosin, 
8 pounds. Boil the lye in a kettle, adding the rosin in portions of 
about a pound at a time, stirring constantly and thoroughly, and 
keeping the heat just about up to the boiling point until saponification 
has been effected. — Ibid., v. 50, p. 134. 
Utz reviews the several suggestions made to demonstrate the com- 
position of the several cresol solutions and to control the identity of 
the official cresol. — Pharm. Zentralh., 1906, v. 47, p. 809. 
Schneider, Hans (Zeitschr. f. Hvgiene u. Infectionskrank, 1906, v. 
53, pp. 116-139), discusses the preparation of ortho- meta- and para- 
sulphonic acids of cresolsulphonic acid, phenolsulphuric acid ester, 
etc., and their value as disinfectants. In Part II he discusses the 
unequal value of commercial cresol soap preparations. — Abstr. in 
Biochem. Centralbh, Leipz., 1906-7, v. 5, p. 253. 
Puppe (Dtsch. Med. Wocli., 1906, p. 424) compares different cases 
of l} r sol poisoning with varying outcomes and reports the post-mortem 
findings in two of his own cases. — Ibid., v. 5, p. 205. 
Blumenthal, F. (Dent. Med. Wchnschr., Berk and Leip., v. 32, Xo. 
32) , states that about 100 cases of lysol poisoning are treated annually 
in Berlin. — J. Am. M. Ass., 1906, v. 47, p. 1062. 
Buckley, J. P., uses cresol and formalin in the treatment of pu- 
trescent pulps. — Dental Cosmos, Phila., 1906, v. 48, pp. 537-544.
