 kala, then gives some to the one whose love is desired. Straightway 

 he adores her. Limu awikiwiki ( Gymnogongrus vermicularis) was used

CHEMICAL ANALYSES AND COMPARATIVE EOOD VALUES OF 



SEAWEEDS. 



The algse when gathered are very succulent and contain a large 

 amount of water. Considerable of this moisture is lost in the various 

 methods of preparation for the table or for other uses. A number of 

 specimens of Hawaiian algse were analyzed by Mr. R. A. Duncan, food 

 chemist of Hawaii, in connection with the writer's investigation of this 

 class of plants, and the results are given in the table below, together 

 with some similar analyses which have appeared in earlier publications 

 of the Office of Experiment Stations and elsewhere. All the samples 

 analyzed were air dry.
