ponification value of 91.9, and the other had an acid value of 83.97 
and a saponification value of 88. — Analytical Notes for 1906, E., L. & 
W., Lond., 1907, p. 12. 
TERPINI HYDRAS. 
Robinson, Frank P., presents a formula for the preparation of 
terpin hydrate from oil of turpentine by nitric acid and hydrogen 
dioxide. — Bull. Pharm., Detroit, 1906, v. 20, p. 155. 
Riedel’s Berichte (Berl., 1906, p. 27) points out that on rapid 
heating terpin hydrate melts uniformly at 116° C. On drying, even 
over sulphuric acid, the substance loses water and melts at 101.5° C., 
or in an air bath at 102° C. 
Utz asserts that terpin hydrate melts at 102° C. in place of 116°, as 
quoted in the Ph. Germ. IV. — -Apoth. Ztg., Berl., 1906, v. 21, p. 930. 
THYMOL. 
Riedel’s Berichte (Berk, 1906, p. 27) asserts that thymol recrys- 
tallized from glacial acetic acid and thoroughly dried, melts at 51° C. 
The anaemia commission reports the use of thymol in anaemia 
(caused by “ uncinaria ”) with excellent results.— J. Am. M. Ass., 
1906, v. 46, p. 1231. 
Quiart (L’Union Pharmaceutique) records the experiences of a 
number of years with thymol as an anthelmintic. Outlines methods 
for its administration. — J. de pharm. d’Anvers, 1906, v. 62, p. 822. 
Cook, George W., considers thymol dissolved in oil of eucalyptus 
a valuable agent in the treatment, especially of the mild forms, of 
chronic blind abscesses (Western Dent. J.). — Dental Cosmos, Phila., 
1906, v. 48, p. 1166. 
Kirk., Edward C., recommends equal parts by weight of thymol 
and phenol crystals in the treatment of pulp cavities and as ideal for 
canal dressing, it being, he claims, sedative, nonirritant, and germi- 
cidal. — Ibid ., v. 48, p. 793. 
Kirk yields to Herman Prinz’s claim to originality in the above 
method.— Ibid., v. 48, p. 1277. 
Schimmel & Co. quote an assertion by Schill that thymol is a good 
remedy against gnats. It is used in the form of a solution of thymol 
in 50 per cent alcohol (2: 100) which is rubbed on the hands, neck, 
and face by means of a cotton wool pad or a piece of woolen rag. — 
Semi-Ann. Rep., 1906, p. 92. 
THYMOLIS IODIDUM. 
The Ph. Belg. Ill includes thymol iodide as “ Biiodobithymolum.” 
Niece, Frank E., presents a formula and outlines the method of 
making thymol iodide. — Proc. Pennsylvania Pharm. Ass., 1906, pp. 
151, 152.
