OXYGEN CONSUMPTION OF OYSTERS 
507 
6. Oxygen consumption of oysters can be increased by adding glucose to the 
water. 
7. Green pigment of oysters is not a hemocyanin or copper proteinate of any 
kind. The compound exists in a highly dissociated state. 
8. Copper content of normal oysters varies between 8.21 to 13.77 milligrams per 
100 grams dry weight, or from 0.16 to 0.248 milligrams per oyster. Copper content 
of green oysters analyzed during the investigation varied between 121.71 and 271.91 
milligrams per 100 grams dry weight, or from 1.24 to 5.12 milligrams per oyster. 
9. Green oysters show a slight increase in oxygen consumption over normal 
oysters. The significance of this difference is, however, doubtful.
