Evans Sons Lescher and Webb report on 8 lots of cajuput oil 
which yielded from 45 to 56 per cent of cineol by the phosphoric- 
acid method; the specific gravity and rotation of these came within 
the generally accepted limits, and only 2 samples were abnormal and 
only became pasty with phosphoric acid. — Analytical Notes for 1906, 
E., L. & W., Lond., 1907, p. 11. 
Smith, Kline & French Co. report on the examination of 3 sam- 
ples of oil of cajuput. The sp. gr. ranged from 0.913 to 0.922 at 
25° C., the optical rotation from —2° 15' to —3° 50', and the cineol 
content from 33 to 45 per cent. These samples were soluble in all 
j parts alcohol and 1 part 80 per cent alcohol. The cineol content in 
i two was below the U. S. P. standard. Lab. Rep. S., K. & F., 1906, 
p. 21. 
OLEUM CARI. 
Schimmel & Co. point out that the specific gravity of oil of cara- 
way (as originally given, 0.905 to 0.915) applies to a temperature of 
15° C., and that for 25° C. it should read 0.899 to 0.909. — Semi-Ann. 
Rep. Schimmel & Co., 1906, Apr. -May, p. 72. 
The Ph. Brit. Committee of Reference in Pharmac}^ report on oil 
of caraway says at least 40 per cent should distill over 200° C., and 
optical rotation — |— 74° to -{-78 °. — Chem. & Drug., Loncl., 1906, v. 69, 
p. 864. 
Braudel, I. W., quotes Sadtler, who asserts that the carvone content 
of oil of caraway can be determined, titrimetrically, with the normal 
sulphite method. — Pharm. Rev., Milwaukee, 1906, v. 24, p. 113. 
Gehe & Co. discuss the probable crop of caraway seed in Holland 
and point out the acreage as well as the yield of seed for the years 
1901 to 1905, inclusive. — Handels-Ber. Gehe & Co., 1906, p. 30. 
Schimmel & Co. discuss the production of oil of caraway, the area 
cultivated with caraway in Holland during the years 1905 to 1906, 
inclusive, the condition of the fields, the average yield per acre, and 
the exports during the years 1900 to 1905, inclusive. — Semi-Ann. 
Rep. Schimmel & Co., 1906, Oct.-Nov., pp. 21, 22. 
Smith, Kline & French Co. report on the examination of 3 sam- 
ples of oil of caraway, in which the sp. gr. ranged from 0.905 to 
0.913 at 25° C., and the optical rotation from -j-78° 43' to +30° 36'. 
They were soluble in all parts of alcohol and in 8 parts of 80 per cent 
alcohol. — Lab. Rep. S., K. & F., 1906, p. 22. 
OLEUM CARYOPHYLLI. 
|l 
Schimmel & Co. assert that as clove oils with as low an eugenol 
content as 80 per cent are admitted, the lower limit of the specific 
gravity should be reduced to 1.033. — Semi-Ann. Rep. Schimmel & Co., 
1906, Apr.-May, p. 73.
