Abstract

1. 1. All fish serum transferrins studied were more acidic than human serum transferrin. 2. 2. Trematomus borchgrevinki serum transferrin was more heat labile than human serum transferrin. 3. 3. Antarctic fish serum had less albumin and more lipoprotein than sera of non-Antarctic fishes and of man, and contained freezing-point-depressing glycoproteins which were absent in all other sera studied. 4. 4. The bloods of two cold-adapted fishes, T. borchgrevinki and trout, clotted faster at 0°C than did the blood of two other non-cold-adapted fish species studied. Bloods of the two mammalian species studied, rabbit and man, had very prologned clotting times at 0°C. 5. 5. The blood of T. borchgrevinki had an apparent minimum clotting time between 25 and 30°C and its capacity to clot was destroyed by incubation at 38-40°C.
