alkali, (cl) the combined alkali, (e) the average molecular weight of 
the fatty acids, also the amount of water and the amount of insoluble 
material. — Ztschr. f. ang. Chem., Berl., 1906, v. 19, pp. 385-388. 
Cohn. Robert, makes a contribution to the knowledge of hydrolysis 
of soap, and reasserts that the amount of free alkali may be deter- 
mined titrimetrically in aqueous solutions without the addition of 
alcohol. — Ztschr. f. offentl. Chem., 1906, v. 12. 
The Ph. Brit. Committee of Reference in Pharmacy would intro- 
duce a test for the nature of the fatty acids in soap. — Chem. & Drug.. 
Bond., 1906, v. 69, p. 864. 
Patch, E. L., found a sample of powdered castile soap 54 per cent 
insoluble in alcohol, 34 per cent talc. Another sample was 30 per 
cent insoluble in alcohol and contained 20 per cent talc. — Proc. Am. 
Pharm. Ass., 1906, v. 54, p. 346. 
Ohliger, Willard, finds castile soap quite commonly adulterated 
with animal fats. — Proc. Michigan Pharm. Ass., 1906, p. 47. 
Sayre, L. E., reports that two samples of powdered soap, supplied 
on an order for Conti, contained animal fats. One sample of Conti 
bar was free from annual fats, while a sample of Mazzini bar con- 
tained animal fat. — Bull. Kansas Bd. Health, 1906, v. 2, p. 175. 
Vanderkleed, Charles E., asserts that very few samples of pow- 
dered soap on the market will conform to the U. S. P. VIII limit of 
alkalinity for soap. — Proc. Pennsylvania Pharm. Ass., 1906, p. 123. 
MacFadden, IV. Lester, considers certain soaps to have a distinct 
value in adjusting bases. In ointments proper (those of a fatty base) 
thev are usually immiscible, but in creams containino- a considerable 
amount of water they are frequently a very happy addition. — Bull. 
Pharm., Detroit, 1906, v. 20, p. 204. 
Rodet, A., ( J. de la parfum. et savonn. franc. 1905, 1906) records 
some experiments on the antiseptic value of soap. — Abstr. in Bio- 
chern. Centralbl., Leipz., 1906-7, v. 5, p. 406. 
SAPO MOLLIS. 
The Ph. Brit. Committee of Reference in Pharmacy would require 
a limit for water in soft soap. — Chem. & Dims:., Lond., 1906., v. 69, 
p. 864. 
Graves, A. (Apoth. Ztg. XXI, Xo. 92, 1906, 990) suggests a process 
for the preparation of soft soap of satisfactory quality. — Proc. Am. 
Pharm. Ass., 1907, v. 55, pp. 683, 684. 
SARSAPARILLA. 
Gelie & Co. point out the marked decrease in the amount of Hon- 
duras sarsaparilla brought to the port of Xew York, and discuss some 
of the reasons for this decline.— Handels-Ber. Gelie & Co., 1906, p. 46.
