MacFadden, W. Lester, discusses the disadvantages and difficulties 
in the use of lard, none of which, he thinks, can be wholly overcome. 
Chemical action is very likely to take place, bringing about decompo- 
sitions that carry on further disintegration, or cause reactions with 
basic substances that ruin the final product utterly. Zinc ointment 
is notorious in this latter respect, and ointments containing mercury 
oxides are positively dangerous. — Bull. Pharm., Detroit, 1906, v. 20, 
p. 204. 
ADEPS LAM. 
The Ph. Austr. YIII includes Lanolinum anhydricum as the 
synonym for Adeps Lanae and Lanolinum as the synonym for Adeps 
Lanae Hydrosus. The Ph. Belg. Ill designates Adeps Lame as 
Lanolinum and Adeps Lanae cum Aqua as “ Lanolinum cum Aqua.” 
The Ph. Brit. Committee of Reference in Pharmacy report that 
Elborne’s modification of the cholesterin test for wool-fat is unneces- 
sary. The iodine value is not of much use. — Chem. & Drug., Lond., 
1906, v. 69, p. 862. 
Endlicher (Pharm. Ztg., li, No. 28, 1906, 321; from Pharm. Post, 
1906, No. 7) points out that commercial adeps lanae should always 
be identified by the pharma copceial cholesterin test, since it is fre- 
quently substituted in the (Austrian) market by products intended 
for cosmetics, which contain no wool-fat at all. — Proc. Am. Pharm. 
Ass., 1906, v. 54, p. 805. 
Lifsclhitz, J. (N. Erfind. u. Erf.), has been able to separate from 
wool-fat the constituents which give it its water-absorbing properties 
by treating a solution of wool-fat in benzine with animal charcoal. 
The latter appears to have the property of absorbing a portion of the 
wool-fat that is not readily soluble in the benzin, but is soluble in 
alcohol, ether, acetone, chloroform, carbon tetrachloride, and carbon 
disulphide. It is asserted that 2 parts of this substance mixed 
with 98 parts of paraffin ointment give to the latter a high degree of 
water absorbing property. — D.-A. Apoth. Ztg., N. Y., 1906-7, v. 27, 
p. 23. 
Dieterich, Karl, reports the examination of a total of twenty sam- 
ples of wool-fat. The residual ash varied from 0.00 to 0.07 per cent, 
the acid number from 0.11 to 0.87, and the water-absorbing prop- 
erty from 130 to more than 250. — Helfenberger Annalen, 1905, 1906, 
v. 18, p. 133. 
Caspari, Charles E., reports two samples examined; both contained 
fatty acids. — Proc. Missouri Pharm. Ass., 1906, p. 101. 
MacFadden, W. Lester, considers the virtues of wool-fat to be 
threefold : Its unique property of taking up water, its textureless 
nature, and the property of ready absorption. By its use ointments 
become directly and genuinely curative media. Medicaments soluble 
in water are easily incorporated, as are also solid extracts, fluid ex-
