Walker and Schreiber have made a comparative study of a number 
of methods proposed for the detection of artificial coloring matter in 
whisky. The authors finally recommend (1) removing the color by 
chloroform, (2) determining the color insoluble in water, (3) de- 
termining the color insoluble in water and extracted by ether, and (4) 
an amyl alcohol test. In addition, they recommend noting the 
character of the solid matter, applying an iron alum test, and a lead 
subacetate test. — Proc. Ass. Off. Agric. Chem., 22 Ann. Conv., pp. 
60-62. 
Crampton, C. A., reports a comparative study by a number of 
analysts of four samples of whisky or distilled liquor. The results 
obtained by the several analysts are given in a table. Some additional 
comments by the several referees are also included. — Ibid ., pp. 45-60. 
SPIRITUS GLYCERILIS NITRATIS. 
Wilbert, M. I., questions the advisability of changing the name of 
this spirit, the word “glonoin” having become well established. — 
Am. J. Pharm., Phila., 1905, v. 77, p. 360. 
Binz, C., discusses the therapeutic application of glyceryl trinitrate, 
reviews the literature regarding its use, and reports a study of the 
decomposition of the compound, with some suggestions on the more 
desirable method of using or of prescribing it. The word “ glonoin ” 
is given as being derived from the initial letters of the constituents: 
glycerin, oxygen, nitrogen, and oxide, with the terminal ending in. —

An editorial discusses the 66 value of nitroglycerin,” and a second, 
“ tolerance to nitroglycerin,” and asserts that when 
Given in well-made gelatin-coated pills or compressed tablets, the pill or tablet 
is so slowly absorbed that the physiological influence persists over a consider- 
able period of time. — Therap. Gaz., 1905, v. 29, pp. 382-383 and 525-526. 
Loomis, H. P., discusses the limitations of the value of nitroglycerin 
as a therapeutic agent. — Med. Pec., N. Y., 1905, v. 67, pp. 411^113 ; 
reference from Inch Med., 1905, p. 355.

Hehner, Otto, discusses the proper application of the word brandy,

employed in the manufacture of Cognac brandy, and defines the terms 
used in the industry. He also discusses the changes in composition 
due to ageing, etc. — J. Am. Chem. Soc., v. 27, 1905, p. 522 (from
