DIGESTIBILITY OF SOME BY-PKODUCT OILS. 9 
oil, Lewkowitsch reports 1 that melon seeds form an article of com- 
merce on the Slave Coast and Gold Coast of West Africa. In studies 
of the relative commercial value of unutilized oil-producing seeds 
and nuts as possible sources of oil, H. S. Bailey, oil specialist of the 
Bureau of Chemistry, gave some attention to this oil. A sample of 
cantaloup-seed oil was expressed from cleaned, dried cantaloup seed 
in a continuous-process-expeller type of oil press under conditions 
approximating those of the commercial oil mill. The cold-pressed oil 
which was obtained was of a light-yellow color without characteristic 
odor or flavor. Since this oil seemed to possess the desirable char- 
acteristics of a table oil, it was decided to determine its digestibility, 
and accordingly three tests were made, the results of which are re- 
ported in the following table :
