Schimmel & Co. discuss the work done by R. Firbas, on the quanti- 
tative estimation of mustard oil and point out that mustard oil de- 
terminations carried out exactly in accordance with the instructions 
of the Ph. Germ. IV, without heating, give results which were about 
8 per cent too low, and according to these no mustard oil would sat- 
isfy the requirements of the pharmacopoeia. They outline a method 
of procedure which they believe to be satisfactory. — Semi-Ann. Rep., 
Schimmel & Co., 1906, Apr.-May, p. 45. 
Brandel, I. W., reviews some of the literature relating to oil of mus- 
tard, its estimation, and its properties. — Pharm. Rev., Milwaukee, 
1906, v. 24, pp. 11—15.

Weigel, G., reviews the current literature on oil of turpentine and 
points out the possible new sources of supply. — Pharm. Zentralh., 
1906, v. 47, pp. 866, 867. 
Francis, John M., calls attention to a turpentine oil distilled from 
sawdust, pine roots, chips, and other refuse of the lumber mills; so 
far little is known as to its characteristics. * * * It will be safer 
to let the painters try it out first. — Bull. Pharm., Detroit, 1906, v. 20, 
p. 142. (See also Proc. Am. Pharm. Ass., 1906, v. 54, p. 343.) 
Lorenz. H. W. F., reviews some of the processes now in use for ob- 
taining products from wood and outlines a method for obtaining 
products from pine wood, particularly wood turpentine, by means 
of a vacuum process. — Oil, Paint and Drug Rep., 1906, Mar. 26, p. 38. 
Schimmel & Co. assert that it would be more correct to fix 0.858 
as the lowest limit for the specific gravity of oil of turpentine. They 
also point out that the U. S. P. VIII lower limit for the specific 
gravity of rectified oil of turpentine applies to a temperature of 15° 
C. ; for 25° C. it is 0.853. — Semi-Ann. Rep. Schimmel & Co., 1906, 
Apr.-May, p. 77. 
Brandel, I. W., reviews some of the recent literature relating to 
American oil of turpentine and to some of the foreign oils of the 
same type. — Pharm. Rev., Milwaukee, 1906, v. 24, pp. 318-320. 
Schimmel & Co. review some of the recent literature relating to 
oil of turpentine, its composition and possible derivatives. — Semi- 
Ann. Rep. Schimmel & Co., 1906, Oct.-Xov., pp. 75-79. 
Herty, Charles H., discusses the composition of oil of turpentine 
and the chemistry of some of its constituents. — Chem. Eng., Phila., 
1906-7, v. 5. p. 233. 
Sundvik, E., points out the distinctive features of so-called “ oil of 
turpentine ” obtained by dry distillation, the differences existing 
between this and the product obtained by distillation with steam, and 
enumerates some of the contaminating substances. — Biochem. Cen- 
tralbl., Leipz., 1906-7, v. 5, p. 701.
