The Ph. Brit. Committee of Reference in Pharmacy suggests that 
the iodine value for lard be introduced and saponification omitted. 
The monograph should be rewritten. — Cliem. & Drug., Loud., 1906, 
v. 69, p. 862. 
Kuhn and Bengen discuss the testing of lard for cotton seed oil, 
point out the conditions under which the Halphen test fails to indi- 
cate the presence of this adulterant, and suggest the use of Bomer's 
phytostearin acetate test in doubtful cases. — Ztschr. f. Unters. d. 
Xaln*. u. Genussm., 1906, v. 12, pp. 145-153. 
Evans, John, comments on the testing of lard for beef stearin and 
cotton seed oil; for the latter he mentions the Ph. Brit, and the 
Halphen tests. — Apothecary, Boston, 1906, v. 18, p. 907. 
Dunlop, H., gives a number of tables showing the results of his 
experiments. He thinks the Keating- Stock method not altogether 
conclusive or satisfactory, and quotes with approval Plehner's re- 
marks on the Belfield test. J. Soc. Chem. Ind., Lond., 1906, v. 25, 
pp. 458-461. 
Barnard, H. E., reports that of 42 samples of lard examined dur- 
ing the year 15, or 35.6 per cent, were adulterated, either by the 
addition of cotton seed oil or beef stearin. — Rep. Indiana Bd. Health, 
25th Ann., 1906, pp. 292, 293. 
Dieterieh, Karl, reports on a total of 30 samples of lard. The 
melting point of these samples was found to vary from 38° to 46° C., 
the samples prepared by Dieterieh himself melting at from 42° to 45° 
C. The acid number varied from 0.44 to 3.75 and the iodine number 
from 44.21 to 65.27. — Helfenberger Annalen, 1905, 1906, v. 18, pp. 
64, 65. 
Smith, Kline & French Co. report on the examination of 4 samples 
of benzoinated lard. One sample was rancid, having an acid num- 
ber of 18.6. Another sample which was claimed by the manufacturer 
to be pure proved to be a vanillated lard, or one odorized with vanil- 
lin. — Lab. Rep. S. Iv. & F., 1906, p. 18. 
Dott, D. B., thinks a combination of the German process, with the 
addition of a simple and direct method of imparting a suitable odor, 
seems likely to give the best result. He has found 60 grains of 
benzoic acid and 40 grains of prepared storax to the pound of melted 
lard give a good result, and he approves the U. S. P. idea of adding 
a little white wax. — Pharm. J., Lond., 1906, v. 23, p. 431. 
Taylor, S., finds Dott's product somewhat dark in color, and still 
requiring to be strained. — Ibid., p. 669. 
The Ph. Brit. Committee of Reference in Pharmacy suggests that 
benzoinated lard be prepared with Sumatra benzoin. — Chem. & Drug,, 
Lond., 1906, v. 69, p. 862.
