be raised somewhat, as an otherwise pure lard was found to require 
upwards of 47° C. — Abstr. Pharm. Ztg. Berlin, 1905, v. 50 , p, 672. 
Wesson and Lane discuss commercial lard and lard compounds, and 
outline the several tests that are useful or needed. — J. Soc. Chem.

An abstract from the Helfenberger Annalen says that of 15 sam- 
ples of lard examined, 5 were objectionable ; 2 because of cotton-seed 
oil, and 1 because of an abnormally high percentage of water. —

Francis, John M., calls attention to the fact that at the present time 
every conceivable quality of wool fat is being marketed, from the 
highest grade to a very crude “ degras.” Some of the lightest 
colored stock that he has seen was distinguished by a terribly offen- 
sive and persistent odor, which rendered it absolutely unfit for any 
salve or ointment. — Bull. Pharm.. Detroit, 1905, v. 19, p. 318. 
Lifschutz, J., discusses the water absorbing properties of wool fat.

An abstract from Seifensieder discusses some of the uses of wool 
fat as a toilet article, its use in soaps, and in various creams designed 
for the prevention and cure of chapped skin. — Deut.-Amer. Apoth.

According to Riedel’s Berichte, Schmitt and Beilstein give the 
boiling point of ether as being from 34.6° to 34.9°, and the experi- 
ments recorded by Riedel would also appear to indicate that the Ph. 
Germ., IV, requirement 35° C., certainly the U. S. P., VIII, require- 
ment 35.5° C., is too high for an ether having a specific gravity of 
0.720 at 15° C.— Riedel’s Berichte, Berlin, 1905, p. 43. 
Rossolimo, A. J., reports complications arising from the use of im- 
pure ether as a solvent in analytical work. — Ber. d. deutsch. chem. 
Gesellsch., 1905, v. 38, pp. 774-775. 
Ditz, H. (Chem. Ztg., 1905, v. 29, pp. 705-710), points out that 
compounds, such as ethyl peroxide and hydrogen peroxide, are formed 
in ether on exposure to air, and that the use of such peroxide ether 
may produce unexpected phenomena when used as a chemical reagent. 
In illustration of this assertion the author recounts a number of ex- 
periments with various modifications of Kreis’s reaction for decom- 
posed or insolated fats. — Abstr. J. Soc. Chem. Ind., Lond., 1905, v. 
24, p. 816. 
An abstract calls attention. to the statement that the contamination 
of ether with hydrogen dioxide is thought to be more frequent than
