osterr. Apt oh.- Yer., Wien, 1906, v. 44, pp. 267-270. 
Moerk, Frank X., points out that the tincture of cinchona repre- 
sents but 18.75 per cent of the alkaloids of cinchona instead of repre- 
senting 20 per cent of the drug as is generally supposed. — Proc. Penn-

CINCHONIDINE SULPHAS. 
Keichard, C., (Pharm. Ztg.) has investigated the reactions of 
quinidine and cinchonidine with various metallic salts, iodic acid, 
potassium ferrocyanide, ammonium persulphate, molybdic, chromic, 
and vanadic acids, etc. He believes that the two bases may be dis- 
tinguished from each other by their reaction with sodium iodate. A 
description of the reactions is given. — Proc. Am. Pharm. Ass., 1906, 
v. 54, pp. 933, 934. 
CINCHONINE SULPHAS.

and the cinchona alkaloids during the year 1905. — Pharm. Rev., Mil-

Herder, M., (Arch. d. Pharm., 244, Xo. 2, 1906, 120) in discussing 
the use of calcium- and barium-mercuric iodides, asserts that when 
cinchonine is treated with the calcium salt in solutions of 1 : 10,000, 
and the barium salt in solutions of 1 : 12,000, a precipitate is formed 
similar to that produced when quinine is treated in the same way. —

CINNALDEHYDUM. 
Schimmel & Co. point out that cinnamic aldehyde is not colorless 
but bright yellow ; they also assert that the statement of the specific 
gravity is not correct — it should read “ 1.048-1.052 at 25° C.’ 1 They 
also call attention to the fact that commercial cinnamic aldehyde is 
usually produced synthetically, as the production from oil of cinna- 
mon or from oil of cassia would be too expensive. — Semi-Ann. Rep., 
1906, Apr.-May, pp. 73, 78. 
They give the following as being characteristic of cinnamic alde- 
hyde: Color, bright yellow; specific gravity at 15° C., 1.054 to 1.058; 
optically, inactive; boiling point, 252° C. with partial decomposition;
