Vive and Budde (Chem. Zt g., Rep., 1905) have experimented with 
mixtures of mercurous chloride and sodium chloride, and find that at 
ordinary temperatures and even at the temperature of the human 
body there is no interaction between these two chemicals. At higher 
temperatures and in concentrated solution there is decomposition. 
They conclude that calomel tablets, made up with perfectly dry pow- 
ders and preserved in a dry place, are indefinitely stable and remain 
unchanged. — Pharrn. Zentralh., 1906, v. IT, p. 485. 
Caspari, Chas. E., reports thirteen samples examined : Eight U. S. 
P. ; four contained mercuric chloride, and one other metals. — Proc. 
Missouri Pharm. Ass., 1906, pp. 51, 99. 
Hemm, Francis, comments on the necessity for testing calomel, and 
does not concur in the opinion that the English product is superior 
to the American. — Ibid ., p. 99. 
An editorial calls attention to the fact that calomel is not wholly 
eliminated by the feces when given by the stomach. Xo conversion 
of calomel into corrosive sublimate occurs in the dog's stomach in an 
hour and a half, and it appears that the absorption due to the pan- 
creatic secretions occurs only in the ileum or large intestine. — X. York 
M. J., 1906, v. 84, p. 754. 
Pisek, G. R., advises the use of calomel or castor oil to run on the 
decomposing food in infantile diarrhoea. — J. Am. M. Ass., 1906, v. 47, 
p. 401. 
Lambkin, F. J., (Lancet, Lond., Xov. 3) advises the intramuscular 
injection of calomel in so-called virulent cases of syphilis; he injects 
it until physiologic effects are obtained, after which he substitutes 
mercurial cream. — Ibid., v. 47, p. 1859. 
The author of an unsigned article states that Metchnikoff and Roux 
prevented the development of syphilis in monkeys, inoculated with 
virulent human material, by inunction with calomel and lanolin. 
Similar results were obtained on a healthy medical student. — Ibid., 
v. 46, p. 1779. 
Metchnikoff and Roux (Ann. de l’Inst. Pasteur, Par., xx, Xo. 10) 
reiterate their former assertions regarding the prophylactic value of 
calomel in lanolin against syphilis. The student inoculated with 
human virus and treated with the calomel ointment has now remained 
free from syphilis for a year. — Ibid., 1907, v. 48, p. 84. 
Gottheil, William S., calls attention to the advantages of treating 
syphilis with intramuscular injections of an insoluble salt of mercury 
which is slowly converted into a soluble salt and absorbed. The 
salicylate is preferred by nearly all syphilographers, calomel being 
the only competitor in this particular. Liquid petrolatum is pre- 
ferred as the suspension fluid for this purpose. The technic of the 
treatment is detailed. — X. York M. J., 1906, v. 83, pp. 1340-1343.
