The oil is a bland, sweet oil with a comparatively high melting 

 point and is light yellow in color. Prof. A. G. DuMez has 

 examined the oil for its physiological properties. He states: 



The oil appears to resemble olive oil very much in its physiological action. 

 Administered to dogs in doses of 1.5 to 3 cubic centimeters per kilogram 

 body weight, it acts as a mild laxative. It is nontoxic and has no 

 irritating action. It can be used in the same manner as olive oil and 

 should be especially useful for culinary purposes. 



Canarium pachyphyllum Perk. — The genus Canarium is widely 

 distributed in the Philippine Islands and is represented by many 

 species. The pili nut of commerce comes from some of these. 

 The Tagalog name is pagsainguin. Two varieties of nuts from 

 Canarium pachyphyllum were examined by us, the long and the 

 short variety. Their description is given in Table VI :
