ON THE RESPIRATORY FUNCTION OF THE BLOOD OF THE SEA LION

MARCEL FLORKIN 1 and ALFRED C. REDFIELD 1

1 HOPKINS MARINE STATION, PACIFIC GROVE, CALIFORNIA

The blood of a sea lion, Eumetopias stelleri, was found to have an oxygen capacity of 19.8 volumes per cent.

The erythrocytes composed 29 per cent of its volume.

One volume of erythrocytes combined with 0.68 cc. oxygen, indicating a hemoglobin concentration 50 per cent greater than that found in domestic mammals.

The oxygen dissociation curves constructed at various pressures conform to the usual mammalian type, but indicate that oxygen may be held at slightly higher pressures than in the case of dog blood.

The carbon dioxide equilibrium is in no way remarkable and exhibits the usual difference between oxygenated and reduced blood.
