the formation of sodium chloride, neutralizing the excess with sul- 
phuric acid and finally titrating with tenth normal silver nitrate 
solution. — J. d. Pharm. v. Elsass-Lothr., 1906, v. 38, pp. 234, 235. 
(See also Chem. & Drug., Lond., 1906, v. 68, p. 253.) 
Selioorl and van den Berg (Pharm. Weekbld., 1906. v. 43) report 
that continued exposure of hydrated chloral to the rays of incandes- 
cent gas light causes partial decomposition of this substance with the 
formation of distinct traces of hydrochloric acid. — Chem. Centralbl., 
Berk, 1906, v. 43, p. 696. 
Enklaar, Johannes E., (Rec. trav. chim., 1906, v. 25, pp. 297-310) 
has extended his investigations on the rate of decomposition of chloral 
hydrate by the action of bases, and tabulates the values of velocity 
coefficient for mixtures of chloral hydrate and barium hydroxide, with 
and without the addition of neutral barium nitrate, choride, acetate, 
propionate, or valerate. — Abstr. in J. Chem. Soc., Lond., 1906, v. 90, 
pt. 1, p. 929. 
Caspari, Chas. E., reports three samples examined: one U. S. P. ; 
two contained chlorides and alcoholate. — Proc. Missouri Pharm. Ass., 
1906, p. 102. 
Lowe, C. B., points out that chloral is directed to be given in 
“ average doses v of 15 grains, while potassium bromide, a much less 
dangerous drug, is directed to be given in the same quantities — 15 
grains.— Proc. Pennsylvania Pharm. Ass., 1906, p. 102, 103. 
A contributor to the “ Pharmacology " column calls attention to 
the fact that somnos is merely looselv combined chloral and glycerin, 
which is unstable and readily yields chloral. — J. Am. M. Ass., 1906, 
v. 47, p. 696. 
The subcommittee’s report to the Council on Pharmacy and Chem- 
istry shows that the action of somnos is practically identical with 
that of a 5 per cent elixir of hydrated chloral. — Ibid., v. 47, pp. 
872-875. 
An editorial discusses the significance and the value of this re- 
port. — Ibid., v. 47, p. 863. 
Mood. H. C., jr., calls attention to the dangers of bromidia. — Ibid., 
v. 46, p. 1220. 
Schulz, W. A., (Am. J. Physiol., v. 16, pp. 483-501) discusses the 
effect of hydrated chloral on the properties of heart muscle. — 
Biochem. Centralbl., Leipz., 1906-7, v. 5, p. 699, 
Carlson, A. J., presents some observations on the action of hydrated 
chloral on the heart with reference to the so-called physiological prop- 
erties of heart muscle. — Am. J. Physiol., Bost., 1906, v. 17, pp. 1-7. 
Rohde, Erwin (Arch. f. experim. Pathol, u. Pharmakol., v. 54. pp. 
104-21), discusses the effects of hydrated chloral on the character- 
istic heart action. — Jaliresb. u. Tier Chem. for 1906, Wiesb., 1907, v. 
36, p. 481.
