Leach, Albert E., reports that all but 1 of 54 samples of solution 
of formaldehyde examined were found to contain from 36 to 40 per 
cent of formaldehyde. The samples classed as adulterated con- 
tained 29.68 per cent of formaldehyde, determined by means of the 
immersion refractometer. — Rep. Massachusetts Bd. Health, 1906, 
p. 402. 
The Ohio Food Com. finds 27 samples of formaldehyde, out of 31 
examined, to be inferior. — Proc. Am. Pharm. Ass., 1906, v. 54, p. 337. 
Smith, Kline & French Co. report on the examination of 16 sam-

McClintic, Thomas B., discusses . the limitations of formaldehyde 
gas as a disinfectant, with special reference to car sanitation, re- 
ports a series of experiments with various methods and a special 
study of the production of formaldehyde gas by the action of potas-

Base, Daniel, reports a study of formaldehyde disinfection and 
the determination of the yield of formaldehyde in various methods 
of liberating the gas for the disinfection of rooms. — J. Am. Chem.

He also discusses the conditions necessary to accomplish success- 
ful disinfection with formaldehyde gas, among these a temperature 
of 68° to 77° F. and an atmosphere nearly saturated with moisture. —

Higley, H. A., (Med. Rec., X. Y., Oct. 20) calls attention to the 
use of formaldehyde as a disinfecting agent and to the fact that its 
penetrating power is practically nil; hence it affects only the sur- 
faces with which it comes in contact. He investigated different forms 
of apparatus for generating the gas. — J. Am. M. Ass., 1906, v. 47, p. 
1512. 
Evans, H. D., is reported to have stated that good disinfection can 
be obtained by using 500 c. c. of formaldehyde solution to which
