HYDRARGYRI IODIDUM FLAYUM. 
Szilard, B. (from Gyogyzs Ertes, 1905, Xo. 46), suggests that 
mercurous iodide may be readily prepared by shaking the mercury 
with chloroform and gradually adding the iodine previously dis- 
solved in another portion of chloroform. The reaction progresses 
rapidly, and should, therefore, be conducted with care; the resulting 
iodide may be washed in the usual way.— Pharm. Ztg., Berlin, 1905, 
v. 50, p. 1009. 
HYDRARGYRI IODIDTJM RUBRUM. 
Penzoldt, F., reviews the use of mercuric iodide in solution with 
potassium, and commends the use of this simple and generally effica- 
cious combination. — Therap. d. Gegenw., 1905, v. 7, pp. 23-25. 
HYDRARGYRI OXIDUM FLAVTJM. 
Pinchbeck, G., presents a number of interesting facts dealing with 
the history of the introduction of yellow mercuric oxide into oph- 
thalmic practice. In connection with this discussion he suggests the 
following general formula: Yellow mercuric oxide, 0.1 to 1.0; an- 
hydrous wool fat, 1.0; spermaceti ointment, or paraffin, a sufficient 
quantity to make 10.0. — Pharm. J., Bond., 1905, v. 21, p. 359. 
Knapp recommends that for the preparation of the ointment of 
yellow mercuric oxide a freshly precipitated yellow oxide be used, 
and suggests that the water may be eliminated by washing first with 
water, then alcohol, and finally ether, and allowing the latter to evapo- 
rate.— Bull. Sc. Pharmacol., Paris, 1905, v. 12, p. 18. 
HYDRARGYRUM. 
Bupp and Xoll record some experiments to adapt a thiocyanate 
solution to the titrimetric determination of mercury in organic com- 
binations. They outline a method that has been adapted to the 
salicylate and the succinimide of mercury. — Arch. d. Pharm., 1905, 
v. 243, pp. 1-5. 
Rupp, E., outlines a method for the titrimetric determination of 
mercury by reducing the respective salts by means of formaldehyde 
and soda solution, converting the mercury to iodide and titrating the 
superfluous iodine with sodium hyposulphite. — Ibid., p. 300. 
Tarugi, X., points out that by the action of mercury vapor on 
metallic aluminum, aluminum amalgam is formed, and that this 
reaction may serve as a sensitive test for mercury. — J. Soc. Chem. 
Ind., Bond., 1905, v. 24, p. 334 (from Gaz. chim. Ital., 1905, v. 34, 
pp. 486-492).
