portion with only traces of oleic acid. Both of these oils differ 

 greatly in melting points from the oils from chaulmoogra and 

 Hydnocarpus reported by Power and his coworkers. 



Pangium edule contains a large amount of olein and smaller 

 quantities of palmitin. 



If hydnocarpic and chaulmoogric esters are specific for leprosy, 

 Pangium edule oil would be an admirable remedy to use, since 

 it would be easy to administer because of its low melting point 

 and consequent fluidity, but would probably be slow in its action 

 on account of the relatively small amounts of these acids pres- 

 ent. On the other hand, Hydnocarpus alcalse oil would be much 

 more difficult of administration because of its being a solid 

 even at the ordinary temperature in Manila (30°C). 



The report of an investigation of the oils from Pangium edule 

 and Hydnocarpus alcalse and of the cyanogenetic glucoside, gy- 

 nocardin, is given. Their properties are discussed in some detail.
