We learn from the preceding results that the Japanese 
fish manure constitutes an essentially nitrogenous fertilizer 
with a rather low content of phosphoric acid, and that the 
difference between sliime kasu and hoshika is considerable, 
the former being richer in nitrogen but poorer in fat than 
the latter. Their average contents in those components 
upon which their value depends is, according to the above 
analyses, as follows :
