1906, v. 23, p. 419. 
Ibid., p. 475, a little boy died while under the influence of ethyl 
chloride for operation purposes. 
Barden, A., (Key. gen. de l’Art Dent., Paris, April, 1906) shows 
that entirely too much confidence has been placed upon innocuous- 
ness of ethyl chloride, which, according to statistics collected up to 
date and referred to in his article, is responsible for 20 fatal cases. — 
Dental Cosmos, Phila., 1906, v. 48, p. 788. 
Long, Eli H., says that the chief objection to ethyl chloride is that 
it is still a new agent ; he thinks it safer than chloroform and com- 
pares favorably with ether. — Ibid., v. 48, p. 817. 
An editorial calls attention to the discussion of ethyl chloride, and 
to the fact that it is far from being the safe agent that some supposed. 
Serious damage to the heart was found to have resulted in a number 
of fatal cases. — Brit. M. J., Lond., 1906, v. 1, p. 1058. 
ALCOHOL. 
Lackey, R. H., quotes a correspondent who points out that the 
U. S. P. requirements are for what is practically known as 190° 
alcohol, and asserts that it is still a common practice to send out 188° 
alcohol. — Proc. Pennsylvania Pharm. Ass., 1906, p. 115. 
Thurston thinks the manufacturers have overlooked the change in 
strength of alcohol, as alcohol of the U. S. P. 1890 strength is being 
generally supplied on orders. — Proc. Ohio Pharm. Ass., 1906, p. 67. 
Vanderkleed, C. E., asserts that all alcohol stamped 190 proof, that 
he has examined, answered the IT. S. P. requirements. — Proc. Penn- 
sylvania Pharm. Ass., 1906, p. 122. 
Ziegler, J., commends the modification of the official, German, 
process for the demonstration of acetone in alcoholic preparations, 
proposed by Eschbaum. — Apoth. Ztg.. Berl., 1906, v. 21, p. 72. 
Klason and Xorlin (Arkiv. Kem. Min. Geol., 1906, v. 2, No. 24, pp. 
1-7) describe a method for preparing a chemically pure ethyl alcohol 
and give its specific gravity as 0.794130 at 15° C. ; the value 0.79429, 
on which Windisch's tables are calculated, indicates that the alcohol 
used by this author contained 0.05 per cent of water. — Abstr. in J. 
Chem. Soc. Lond., 1906, a t . 90, pt. 1, 921. 
Buchner and Meisenheimer discuss the chemical changes that take 
place in the course of alcoholic fermentation, and the products that 
are formed (Chem. Ber., 1906, v. 39, pp. 3201-3218). — Biochem. 
Centralbl., Leipz., 1906-7, v. 5, p. 743. 
Mannj E. A., discussing a possible new commercial source of 
alcohol, gives the yield from various materials in proof gallons per
