salts make the use of these appear as promising remedies. But 

 Rogers cautions against the assumption of a too optimistic at- 

 titude, as he regards the problem as still unsolved. On the 

 other hand, it seems likely that antileprol and the neutral oil 

 should be more effective than they have been found to be, if 

 cures result from the use of the free acids and of the sodium 

 salts. Consequently the inactivity of antileprol and of many of 

 the commercial chaulmoogra oils should make practitioners cau- 

 tious about accepting a remedy as specific for leprosy until it is 

 proved to be such. 



SUMMARY 



The constants of ten samples of chaulmoogra oil are given. 

 A chemical examination of chaulmoogra oil is included. The use 

 of various fractions of chaulmoogra in the treatment of leprosy is 

 discussed, and the desirability of chemical investigation accom- 

 panying the medicinal administration is pointed out.
