sulphuric acid solution of morphine. — J. Am. Chem. Soc., 1905, v.

Frankforter and West outline a method for the gasometric de- 
termination of formaldehyde, which depends on the liberation of 
hydrogen from a mixture of formaldehyde, caustic alkali, and hydro- 
gen peroxide. — Ibid ., pp. 714-719. 
Lyons. A. B.. proposes a modification of Hehner’s test so as to 
make it applicable for the detection of formaldehyde in liquids 
other than milk. The test depends on the presence of proteids, which 
he proposes to introduce in the form of beef peptone. He asserts 
that the test will show the presence of 1 : 4000000 parts of formalde- 
hyde. — Proc. Am. Pharm. Ass., 1905, v. 53, pp. 326-329. 
Linclet (Apoth. Ztg.) proposes the use of casein, dilute ferric chlo- 
ride solution, concentrated phosphoric and sulphuric acids for de- 
tecting formaldehyde in alcohol. — Drug. Circ. & Chem. <4az.. 1905, 
v. 49, p. 390. 
Puckner, W. A., discusses the L T . S. P.. VIII, test for formaldehyde 
in witch hazel extract, and concludes that the official test when prop- 
erly applied will show the presence of 1 gm. of formaldehyde in 
10000 cc. of a 15 per cent alcohol solution. To avoid possible failure 
he suggests that the test be made to read : 
If 1 cc. of liamamelis water be added to 5 cc. of a freshly prepared solution 
of 0.01 gm. of salicylic acid in 100 cc. of sulphuric acid, no red color should ap- 
pear on standing (absence of formaldehyde). — Am. J. Pharm.. Phila., 1905, y.
