THE STUDY OF COPRA AND OTHER COCONUT PRODUCTS » 



By Alvin J. Cox 

 (From the Bureau of Science, Manila) 



For several years the chemists, assisted by the botanists, of 

 the Bureau of Science have been employed, as time permitted, 

 in a study of the products of the coconut. Many investigations 

 have been made and published by the Bureau of Science on the 

 subject. 2 Coconut oil as such and in the unpressed copra ranks 

 among the three most important exports from the Philippine 

 Islands and, therefore, warrants careful study. There are two 

 large operating vegetable oil plants in the Philippine Islands,
