A digest of the regulations and instructions concerning the denatur- 
ing of alcohol is presented. — Sci. Am. Suppl., 1906, v. 62, pp. 25754- 
25755, 25758-25759, 25778-25779. 
Baskerville, C. (Amer. Mo. Rev. of Reviews, 34, 1906, No. 199, 
pp. 211-214), discusses briefly the uses of alcohol, its manufacture, 
and denaturization. Also suggests certain social and economic condi- 
tions likely to result from the removal of the tax upon denatured 
alcohol. — Exper. Sta. Rec., 1906, v. 18, p. 191. 
Diedericks, H. (Internat. Mar. Engin., 1906, pp. 263-270), gives 
a very complete resume of the use of alcohol as a fuel for gas engines, 
discusses the fuel value of alcohol generally, and presents some infor- 
mation on the denaturing agents used in different countries, this 
information being drawn mostly from German practice. He con- 
siders the fuel value and physical properties of alcohol and the 
details of the alcohol engine wherever they may be different from 
the gasoline or crude oil engine. — Exper. Sta. Rec., 1906, v. 18, 
p. 190-191. 
Ladd, E. F., urges the association to use its influence to have dena- 
tured alcohol designated by some other distinctive name that could 
not be mistaken for alcohol, as now used ; this, he thinks, would pre- 
vent serious mistakes. — Proc. Xortli Dakota Pharm. Ass., 1906, p. 39. 
Thurston savs the use of wood alcohol, internally or externallv, 
should be seA^erely condemned. He has found it in a number of 
preparations, such as liniments, bay rum, spirit of camphor, tincture 
of iodine, and witch hazel. — Proc. Ohio Pharm. Ass., 1906, p. 67. 
Coblentz, Virgil, having found, in Xew York, many samples of 
tincture of arnica, iodine, and some of camphor made up with pure 
wood alcohol, presents an abstract of Schmidt’s article in Arch. d. 
Pharm., 243, 555, with additions. — Apothecary, Boston, 1906, v. 18, 
p. 910. • 
Scudcler and Riggs discuss the detection of methyl alcohol and 
outline a modification of the Shangle-Ferriere-Cumiasse test. — J. Am. 
Chem. Soc., 1906, ax 28 , p. 1203. 
Voisenet, E., describes a method of detecting methyl alcohol in 
ethyl alcohol, consisting in the obtaining of a violet coloring matter 
Avhen an albuminoid substance is treated with hydrochloric or sul- 
phuric acid slightly nitrous in the presence of traces of formic alde- 
hyde. It is very sensitAe (1 : 20.000), simple, and rapid. — Bull. Soc. 
de cliim. Par., 1906, v. 35, pp. 748-760. 
ALOE. 
The Pli. Brit. Committee of Reference in Pharmacy asserts that no 
aloin-assay method is accurate. The monographs for aloes require 
complete revision. — Chem. & Drug., Bond., 1906, ax 69, p. 862.
