C. llie Serum of the Dogfish. — Two determinations of the A of the serum 

 gave — 2"035°, and two of that of the salts of the serum gave — 1'075° and 

 — 1-0725° the mean of the two being -1-0737°. The total salts of the 

 serum in these two cases amounted to 1"775 per cent, and 1-7729 per cent., 

 and the mean was 1-7739 per cent. The total solids, as ascertained in 

 one determination, were 5-956 per cent. The analyses gave :

D. The Serum of tlie Cod. — The solids of the serum of the cod gave in 

 three different determinations 7-165, 7-1006, and 7'170 per cent., the mean of 

 which is 7-1452 per cent. In one determination the total salts were 

 1*2823 per cent., and this gave a A of —0-71° C, while that of the blood of 

 two very large cod, ascertained within two and a-half hours after their 

 ■capture, was —0-765° C. The chlorides of sodium and potassium present 

 amounted in three determinations to 1-1326, 1-1349, and 1-1293 per cent., 

 the mean of which was 1-1322 per cent. The results of the analyses of the 

 ash were :
