by a useless or even successful attempt at their substitution. — J. Am. 
M. Ass., 1905, v. 45, p. 1441. 
Schwarz, Osw., elaborates on the work done by Pollack on the 
antiferment of trypsin and recounts some experiments that he has 
made with pepsin. He finds that on heating a pepsin solution an 
inhibiting body is liberated. This inhibiting body, or antipepsin, 
he believes to be present normally in pepsin. — Chem. Centralbl., 
1905, v. 76, p. 341 (from Beitrage z. chem. Physiol, u. Pathol., 1905, 
v. 6, pp. 524-542). 
PETROLATUM. 
van der Wielen, P., proposes the following formula for a petro- 
latum compound that is said to be capable of taking *up and holding 
as much as 75 per cent of water or of aqueous solutions, and should, 
therefore, be used as an ointment base. For a white cerate he sug- 
gests 5 parts of white wax and 95 parts of white petrolatum and for 
the yellow cerate a corresponding quantity of yellow wax and petro- 
latum. — Pharm. Ztg., Berlin, 1905, v. 50, p. 552. 
PETROLATUM LIQUIDUM. 
Yanderkleed, Charles E., points out that all qualities of liquid 
petrolatum are to be had on the market and that pure goods can 
readily be obtained by paying the right price. The presence of 
traces of free acid and of sulphates should be guarded against. — Proc. 
Pennsylvania Pharm. Ass., 1905, p. 55. 
PHENOL. 
Lyons, A. B., points out that there is an inconsistency between the 
statement of solubility, in water, of phenol and of liquified phenol. — 
Proc. Am. Pharm. Ass., 1905, v. 53, p. 260. 
Riedel’s Berichte points out that Schmidt, Beilstein, Kahlbaum, 
and other investigators give figures, for the boiling point of phenol, 
that range from i82 to 184.1° C., and the experiments recorded in 
Riedel’s Berichte appear to indicate that the upper limit, 182°, of 
the pharmacopoeia is too low. — Riedel’s Berichte, 1905, p. 42. 
Yanderkleed, Charles E., calls attention to the possibility of the 
95 per cent “ carbolic acid solution ” of the chemical manufacturer 
may contain only 91.2 per cent of absolute phenol. — Proc. Pennsyl- 
vania Pharm. Ass, 1905, p. 193. 
Lloyd, S. J., presents an exhaustive study of the attempts to devise 
a satisfactory method for the quantitative estimation of phenol. He 
presents a record of his analyses and some suggestions on the condi- 
tions under which phenol can be accurately determined. — J. Am. 
Chem. Soc., 1905, v. 27, pp. 16-24.
