Brandel, I. W., reviews some of the literature relating to oil of 
rose, its production, properties, and composition. — Pharm. Rev., Mil- 
waukee, 1906, v. 24, pp. 15-16, 39—10. 
Schimmel & Co. assert that the U. S. P. VIII upper limit for 
specific gravity of oil of rose is too low and should be 0.86T, at 25° C. 
The upper limit for the congealing point, they believe, might be 23.5° 
C., and they assert that they have observed pure oils with saponifica- 
tion numbers ranging from 8.5 to 19. — Semi-Ann. Rep., 1906, Apr.- 
May, p. 75. 
The} 7 point out that the limits for the specific gravity of oil of rose, 
at 30° C., are 0.849-0.862. — Ibid., Oct.-Nov., p. 87. 
Parry, Ernest J., says from the experience of many years’ crops 
and from samples taken from all over the rose-gathering areas he is 
convinced that a pure otto of rose never (that is, when distilled in 
normal Bulgarian fashion) has a specific gravity over about 0.855. 
It usually falls between the limits 0.850 and 0.853 at 30° C., and 
anything over this is at once suspicious. — Chem. & Drug., Lond., 
1906, v. 69, p. 230. 
Francis, John M., says it is well to remember that while the finer 
brands of synthetic otto of rose are splendidly fitted to be used with 
the natural oil they are not by any means fit substitutes, and he who 
forgets this will come to grief with his cherished cream or lotion. — 
Bull. Pharm., Detroit, 1906, v. 20, p. 141. 
Schimmel & Co. discuss the production of oil of rose in Bulgaria, 
and the efforts that are being made to increase the cultivation and the 
yield of oil of rose and to control adulteration. — Semi-Ann. Rep., 
Schimmel & Co., 1906, Oct.-Nov., pp. 65-67. 
Simmons, W. H., reports meeting with two samples of oil of rose 
contaminated with ethyl alcohol. As in both cases only a very small 
quantity of alcohol was present, he is inclined to believe that it was 
an accidental rather than an intentional contamination. — Chem. & 
Drug., Lond., 1906, v. 68, p. 20. 
OLEUM ROSMARINI. 
Schimmel & Co. point out that they have met with good oil of 
rosemary with an ester content as low as 1.2 per cent and a total con- 
tent of borneol down to about 10 per cent. — Semi-Ann. Rep. Schim- 
mel & Co., 1906, Apr.-May, p. 75. 
Gane, E. H., asserts that the pharmacopceial requirements are too 
high, as evidenced by the fact that no oil of U. S. P. standard is 
obtainable in the New York market. Reports on 5 samples which 
were found to contain from 2 to 2.6 per cent of ester and from 8 to 
12.6 per cent of total borneol. — Proc. Am. Pharm. Ass., 1906, v. 54, 
p. 342.
