OLEUM ROS.E. 
Umney and Bennett point out that the U. S. P., VIII, is the first 
pharmacopoeia to include the saponification value for oil of rose. 
They also assert that — 
Given that the physical and chemical characteristics indicate purity, then it is 
advantageous not to have a higher congealing point than 20° C., as a higher 
boiling point indicates naturally a greater proportion of odorless stearopten. — 
Pharm. J., Lond., 1905, v. 21, p. 147. 
An abstract quotes the limits of composition and the constants of 
Bulgarian oil of rose as given in Schimmel & Co.’s report for 1901,

OLEUM ROSMARLNX 
Umney and Bennett are disposed to think the minimum percentage 
of borneol, 15 per cent, somewhat high, and suggest that 12.5 per 
cent would have been quite high enough. [U. S. P., VIII, 1907, 
reduced to 10 per cent.] — Pharm. J., Lond., 1905, v. 21, p. 147.
