It was at first intended to identify each organism which was used 

 exiierimentallj^, but this was found to be iniiii-acticable in this country 

 wliere all literature is not available, except in the case of two molds, 

 Aspergillus catenatiis and Aspergillus flavus. It also seems ijrobable 

 that the majority of the other organism found in moldy copra in the 

 Philippines are new and not yet described, and our mycological work is 

 not yet far enough advanced to render descriptions of them possible. 

 However, the main object of the experiments, namely the differentiation 

 between mold and bacterial action on copra, has been accomplished. It 

 is evident that in every tube containing an active mold culture, a decided 

 loss in total weight (dry), ranging from 5 to 11 per cent of the original 

 weight, occurs if the gain or loss in dry coj)ra is first considered.
