CHLORALTJM HYDRATUM. 
Siedler, P., points out that the Ph. Germ., IY, requires a melting 
point of 58° C. ; his experiments would appear to indicate that 
hydrated chloral melts at 57°, — Pharm. Post, Wien, 1905, v. 38, 
p. 568. 
Kebler, Lyman F., reports a sample of hydrated chloral which 
melted at 51° C. and contained chloride and chloral alcoholate. — 
Proc. Am. Pharm. Ass., 1905, v. 53, p. 183. 
Schoorl and van den Berg give some account of investigations made 
to determine the nature of the decomposition produced in hydrated 
chloral, under varying conditions, more particularly under the in- 
fluence of air and light. — Ber. d. pharm. Gesellsch., Berlin, 1905, 
v. 15, p. 414. 
Enklaar, J. E. (from Recuil des Trav. Chirn., v. 23, pp. 419^38), 
presents a study of the action of alkalies on hydrated chloral. — 
Pharm. Weekbl., 1905, v. 42, pp. 170-174. 
Bhode, E. (Centralbl. f. Physiol., 1905, v. 19, pp. 503-504), reports 
some observations on the toxic action of hydrated chloral on the 
frog’s heart. — Biochem. Centralbl., 1905, v. 4, p. 546. 
Kabbagliette (Le Monde Dent.. Paris, 1905) discusses the treat- 
ment of odontalgia with a 15 per cent solution of hydrated chloral 
in glycerin. — Dental Cosmos, Phila., 1905, v. 47, p. 1137. 
CHLORALFORMAMIDUM. 
An editorial, in discussing the additions to the U.' S. P., VIII, 
says of chloralformamidum : 
The chemical term for chloralamide. More prescribed, on the continent of 
Europe than in the United States, where its use is decreasing. — Drug Topics, 
1905, v. 20, p. 196. 
CHLOROFORMUM. 
Francis, John M., points out that too much care can not be exer- 
cised in procuring chloroform of proper quality, and, more important 
still, that its peculiarities should be recognized and that adequate 
precaution be taken to insure that it reach the surgeon's hands in 
good condition. A sample which conforms to all of the requirements 
of the pharmacopoeia may, he asserts, become unfit for anaesthetic 
purposes within a month bv bad usage. — Bull. Pharm.. Detroit. 1905, 
v. 19, p. 364. 
Riedel’s Berichte quotes Schmidt as giving the boiling point of 
chloroform as varying from 59° to 61° and points out that this con- 
forms very closely with the results recorded by Riedel, who finds that 
the higher requirement of the Pli. Germ., IV, 62° is too high, while 
the lower 60° is not sufficiently low. For varying barometric pres-
