Francis. John M., comments on the addition of lime water to the 
formula, and the old pharmaceutical puzzle as to why bichloride of 
mercury is not precipitated by lime water in the presence of acacia. — 
Bull. Pharm., Detroit. 1906, v. 20. p. 98. 
Bedall, C., suggests that mucilage of acacia be made with distilled 
water that has been boiled and allowed to cool in a closed vessel 
so as to exclude as much as possible the absorption of air. The 
mucilage is to be made in a bottle that is completely filled bv the 
i ; i. t 
mixture of acacia and water, the object being to exclude air and 
prevent decomposition of the acacia. — Apoth. Ztg., Berl., 1906, 
v. 21, p. 852. 
TCippern, Franz, recommends the making of mucilage of acacia 
with recently boiled distilled water. He asserts that when made with 
distilled water free from micro-organisms, air. and carbon dioxide 
mucilage of acacia is clear and keeps \£ell. particularly if preserved 
in small, well-stoppered bottles. — Pharm. Ztg.. Berl.. 1906, v. 51, 
p. 807. 
Beckstroem. R.. suggests that the Ph. Germ, require that mucilage 
of acacia be made with freshly boiled and cooled water. — Ber. d. 
pharm. Gesellsch., Berl., 1906. v. 16. p. 326. 
Buhrer. C.. discusses the preparation of mucilage of acacia and 
points out that all acacia contains an oxydase which may be destroyed 
by heating for twelve minutes or more on a water bath. The steril- 
ized mucilage is opalescent, but is otherwise not changed. — Schweiz. 
Wchnschr. f. Chem. u. Pharm., 1906, v. 44, p. 543. 
Alpers, IV. C., points out that mucilage of acacia can readily be 
prepared by means of circulatory displacement and outlines the 
method that he uses. — Proc. Am. Pharm. Ass., 1906, v. 54. p. 506. 
IV atson. IV. H., suspends the acacia in a cheese-cloth or other suit- 
able strainer in the lime water with an equal amount of water and 
places the apparatus on ice or in the cool for a few hours, then with- 
draws the strainer and adds water to make the required weight. — 
Drug. Cir. & Chem. Gaz. X. Y., 1906, v. 50. p. 133. 
ACETANILIDTJM. 
The Ph. Austr. VIII. and the Ph. Belg. III. include antifebrinum 
as the synonym for acetanilide. 
Riedel's Berichte points out that the melting point of acetanilide 
is variously given as being 113, IT. S. P. VIII; 113-114. Ph. Germ. 
IV; 112, Ph. Austr. VIII; 112-113, Ph. Helv. ; 113.5, Ph. Brit.; 114, 
Ph. Fr. Riedel points out that for concordant results it is. neces- 
sary to dry the acetanilide carefully over sulphuric acid. TVith re- 
crystallized material he found the melting point to be 113.5° C.. and 
in an air bath. 114.5° C. — Riedel's Berichte, Berk, 1906, p. 21.
