investigation. — Chem. & Drug., Lond., 1906. v. 69, p. 865. 
Herder, M., recommends calcium and barium-mercuric iodides as 
sensitive reagents for strychnine and its salts. — Arch. d. Pharm., 
Berl., 1906, v. 244, p. 120. 
Wiebelitz, H., asserts that the addition of strychnine to strong 
sulphuric acid causes a partial decomposition of the strychnine and 
that this decomposition is the cause of the light yellow color usually 
produced. He suggests that the test be made more complete by pre- 
scribing actual quantities. — Pharm. Ztg., Berl., 1906, v. 51, p. 1004. 
Hill, J. Butlierford, calls attention to the incompatibility of strych- 
nine salts with medicated waters made with magnesium carbonate. — 
Pharm. J., Lond., 1906, v. 22, pp. 224-225. 
Brown, Orville Harry, discusses a colloidal compound of strych- 
nine and its pharmacology. — J. Biol. Chem., X. Y., 1906-7, v. 2, pp. 
149-157. 
v. Ketlv, Ladislaus, discusses the use of strychnine in the treatment 
of a variety of forms of diabetes. — Therap. d. Gegenw., Berl., 1906,

Giles, P. B., reports 9 cases of heat stroke in which he used strych- 
nine with marked success. — Brit. Med. J., Lond., 1906, v. 2, p. 596. 
Morgan, A. C., states that strychnine is always valuable as a heart 
tonic in pneumonia, combined with nitroglycerin if the arterial ten- 
sion is high and with atropine if the tension is low. — X. York M. J., 
1906, v. 84, p. 745. 
Robinson, William J., states that strychnine is the remedy par 
excellence for loss of tone and functional atony of every character.

but there are a number of disadvantages attending its use. — J. Am. 
M. Ass., 1906, v. 47, pp. 2145, 2146. 
Wells, G. Harlan, finds strychnia a powerful stimulant to the 
heart muscle and its ganglia and to the vasomotor center; on account 
of its general tonic effect strychnia given in moderate doses is valu- 
able in many forms of myocardial weakness associated with general 
malnutrition and depressed nervous conditions. He cautions against 
its continued administration in large doses for more than a few days, 
as the continued stimulation may exhaust the heart. — Hahneman. 
Month., Phila., 1906, v. 41, p. 261.
