E. The Serum of the Pollock — The solids in the serum of the pollock 

 amounted in one determination to 7'095 per cent. The total salts in 

 another estimation were 1"2934 per cent., and the A for the salts of this 

 determination was — 0"737° C, while the A for the serum was — 0'825° C. 

 The analyses of the ash gave :
