if the heating is done in a flask with a funnel in the neck to avoid 
unnecessary loss. He also advises heating the finished solution, in 
a porcelain vessel, directly over the fire, and asserts that this com- 
bined change will materially shorten the time required to make this 
preparation. — Ber. d. pharm. Gesellsch., Berl., 1906, v. 16, p. 339. 
The Ph. Brit. Committee of Reference in Pharmacy report on 
strong solution of ferric chloride says a solution of specific gravity 
1.42 does not yield the quantity of ferric oxide stated. The specific 
gravity might be altered to 1.49 ; the yield of oxide would then be 
1.6 grammes for 5 cc. — Chem. & Drug. Loud., 1906, v. 69, p. 864. 
Lefeldt, Max, suggests that the directions for preparing liquor 
ferri oxychlorati, Ph. Germ. IY, should specify that the washing of 
the magma be done as rapidly as possible. The making of the prep- 
aration should not extend over two days, as the precipitate loses the 
property of dissolving in the prescribed amount of acid. — Ber. d. 
pharm. Gesellsch., Berl., 1906, v. 16, p. 338. 
Yanderkleed, Charles E., found one sample of solution of ferric 
chloride testing 13.1 per cent of metallic iron, and, in striking contrast, 
another sample which assayed only 6.55 per cent of metallic iron 
instead of the required 10 per cent of the U. S. P. VIII. — Proc. 
Pennsylvania Pharm. Ass., 1906, p. 123. 
Barnard, H. E., . reports that of ITT samples of tincture of ferric 
chloride examined, 138, or T8.5 per cent, were below the U. S. P. 
VIII, standard. He concludes that the low percentage of iron may 
be due to the use of impure chemicals, incomplete solution, or care- 
lessness in preparation, as samples prepared according to the U. S. P. 
method complied fully on analysis. — Rep. Indiana Bd. Health, 1906, 
pp. 387-390. 
Brown, Linwood A., reports examining IT samples of tincture of 
ferric chloride which varied from 4.10 to 6.50 per cent of iron, or 
from 89.5 to 136 per cent of the required U. S. P. VIII strength. — 
Rep. North Dakota Agric. Exper. Stat., 1906, Part II, p. 152. 
Nieder, C. F., recommends the use of tincture of ferric chloride and 
quinine sulphate in the treatment of pneumonia. — J. Am. M. Ass., 
1906, v. 47, p. 272. 
Reilly, T. F., states that massive doses of quinine sulphate and 
ferric chloride, lauded as a specific for pneumonia in the Southwest, 
do not give the desired results in the East. — Ibid ., v. 4T, p. 649. 
Lambert, Alexander, states that iron perchloride and silver nitrate 
are much used in gastric ulcer to promote cicatrization, the silver 
nitrate being much the more useful. — Ibid., v. 47, p. 847. 
FERRI HYDROXIDUM. 
Hill and Unmet" suggest a new nomenclature for ferric oxide and, 
incidentally, give an interesting table of 19 official names, together
