u. Genussm^, Berlin, 1905, v. 10, p. 242. 
Fendler, G., reviews the literature and the tests bearing on the 
detection of boric acid when used as a preservative in foodstuffs. — 
Apoth. Ztg., Berlin, 1905, v. 20, p. 757. 
Hefelmann, Rudolf, discusses the demand that has been made to 
provide for the quantitative estimation of boric acid in all cases 
where it occurs in foods preserved with salt. The author concludes 
that the amount of boric acid in salt is so minute that it would not 
likely be found as such in the course of the ordinary inspection 
analysis. — Ztschr. f. offentl. Chem. 1905, v. 11, pp. 231-234. 
Vaubel and Bartelt (Chem. Zeit., 1905, v. 29, pp. 630-631), point 
out that sulphurous acid in solution in which boric acid is to be 
determined by titration in the presence of glycerol, using phenolph- 
thalein as an indicator, must be removed by a preliminary treatment, 
otherwise too low results are obtained. To accomplish this they 
recommend boiling the solution after the addition of a strong min- 
eral acid. — Analyst, London, 1905, v. 30. p. 285. 
An abstract (from Chem. Ztg., 1905, No. 46) reviews the several 
tests devised for the quantitative estimation of boric acid. — Pharm. 
Ztg., Berlin, 1905, v. 50, p. 563. 
Windisch, K. (Ztschr. f. Unters. d. Nahr. u. Genuss., v. 9, p. 641), 
outlines a method for the determination of boric acid in wines, fruit- 
juices, etc. — Pharm. J., Lond., 1905, v. 21, p. 230. 
Rost, E. (Deutsch. Med. Wochnschr., No. 2, 1905), discusses the 
effect of boric acid and borax on the animal organism, controverting 
the statements made by Liebreich. — Nouv. Rem., 1905, v. 21, p. 452. 
Rost, E. (Arch, internat. de Pharmacod., 1905, v. 15, p. 291), 
reports a number of observations on rabbits, dogs, and men, bearing 
on the absorption and elimination of boric acid. A comprehensive 
literature of the subject, comprising practically all that has been 
published regarding pharmacologic, bacteriologic, therapeutic, and 
toxicologic properties of boric acid is appended. — Biochem. Centralbl. 
1905, v. 4, p. 447. 
Abstract (from La Nuova Riv. Terap., No. 1, 1905) includes a 
report of five fatal cases of poisoning by boric acid, to which Frank 
H. Pritchard adds a case of alarming prostration from intestinal 
irrigations, but with recovery. — Hahneman. Month., Phila., 1905, 
v. 40, p. 386. 
ACIDUM CAMPHORICUM. 
An editorial, in discussing the additions to the U. S. P., VIII, says 
of camphoric acid : 
Presumably introduced out of deference to German opinion, as it is not very 
extensively used here. — Drug Topics, 1905, v. 20, p. 195.
