meat extract, which, he finds, does not always have the same composi- 
tion. — Chem. Centralbl., Berl., 1906, v. TT, II, p. 117. 
Ohliger, Willard, reports beef extract made from meat furnished 
by one of the large Chicago packing houses, which turned decidedly 
red after a time, due to red coloring matter added, probably, to main- 
tain the original flesh color of the meat. The extract gave tests for 
appreciable amounts of analine dye. — Proc. Michigan Pharm. Ass., 
1906, p. 46.

glycerinated calf lymph to temperatures below freezing point. —

XANTHOXYLUM. 
Henkel, Alice, mentions Xanthoxylum americanum Mill., also 
known as Xanthoxylum fvaxineum Willd., commonly known as 
xanthoxylum, northern prickly ash, and toothache-tree, as common 
in woods and thickets, and along river banks from Virginia, Mis- 
souri, and Nebraska northward to Canada. — Bull. Bur. Plant Ind., 
U. S. Dept. Agric., 1906, No. 89, p. 76. 
Gordin, H. M., reports a study of the crystalline principle found 
in prickly ash bark and particularly of the difference, if any, exist- 
ing between xanthoxylin of the northern prickly ash and the corre- 
sponding principle found in the southern prickly ash bark. — J. Am. 
Chem. Soc., 1906, v. 28, pp. 1649-1657. 
ZINCUM. 
Coblentz, Virgil, says that while the presence of sulphates and 
chlorides may be ignored in the alkali salts, it must be restricted in 
such zinc salts as the bromide, iodide, and valerate, which are given in 
fair-sized doses, extending at times over greater periods. — Am. J. 
Pharm., Phila., 1906, v. 78, p. 395.
