specific gravity at 15° C. varied from 0.892 to 0.895. — Proc. Pennsyl-

Patch, E. L., reports on a sample of acetic ether which was only 
83.6 per cent pure. — Proc. Am. Pharm. Ass., v. 54, p. 337. 
Ohliger, Willard, reports a sample of ethyl acetate containing 
over 10 per cent impurities. — Proc. Michigan Pharm. Ass., 1906, p. 47. 
^ETHYLIS CHLORIDUM. 
Webster, W., finds that ethyl chloride, ethyl bromide, ethyl iodide, 
and sonmoform all have practically the same physiological action. 
Such differences as exist between them are only of degree, and appear 
to depend on the extent of their volatility. His results as regards 
the effects of ethyl bromide and somnoform on the vagus are dia- 
metrically opposed to those of Cole (Brit. Med. J., June 20, 1903), 
but in Swale Vincent’s opinion are fully justified by the tracings. — 
Biochem. J., Liverpool, 1906, v. 1, pp. 328-340. 
Hawley, G. F., reviews the literature of ethyl chloride and dis- 
cusses the technic of anesthetization with it. — J. Am. M. Ass., 1906, v. 
47, pp. 502-505. 
Osmond, A. E., illustrates a method of using an ordinary funnel 
for the administration of ethyl chloride for anesthesia. — Ibid., v. 47, 
p. 1655. 
Syme, W. S., describes a simple method of administering ethyl 
chloride, which he has used three or four hundred times and which 
provides for the continuous admission of the air. — Brit. Med. J., 
Bond., 1906, v. 2, p. 197. 
Manwaring, J. G. R., (J. Mich. State Med. Soc., Detroit, Nov.) 
used ethyl chloride for anesthesia in 104 cases. Nausea was as fre- 
quent as it would have been with chloroform. — J. Am. M. Ass., 1906, 
v. 47, p. 2038. 
Luke, T. D., (Lancet, Lond., May 5) refers to 22 fatalities occur- 
ring under ethyl chloride anesthesia. — Ibid., v. 46, p. 1731. 
Friedland, M. M., cites 2 deaths in New York during the decade 
1895-1905 in an estimated number of 2,190,000 administrations of 
nitrous oxide; ethyl chloride, 12,436 cases with but 1 bona fide 
death, though he cites 2 fatalities under ethyl chloride. — Dental 
Cosmos, Phila., 1906, v. 48, pp. 835-839. 
Ware, Martin W., criticises Friedland’s presentation and thinks 
a death rate for ethyl chloride of 1 : 40,000 is more nearly correct. — - 
Ibid., p. 1022. 
Friedland replies. — Ibid., p. 1207.
