With regard to the methods applied in the present 
researches, the organic part of the manures was analyzed 
in the same way as described in Bulletin No. 2 (p. 5-6) for 
the feeding stuffs, and the ash according to E. von Wolffs 
“Anleitung zur Untersuchung landwirthschaftlicher Stoffe.” 
The nitrogen was estimated by Kjeldahl’s method, and the 
phosphoric acid in the fish manure and sea animalsw as 
determined after oxidation of the substances with strong 
nitric acid and fusion with carbonate and nitrate of soda by
