The percentage of C14 activity in the glycogen fractions had increased during the 96 hours from 1 or 2% to 5 or 6% at the low salinities. The C14-activity associated with lipids increased slightly with salinity at the 3 hour interval (Fig. 8), but did not show any variation with salinity at the 99 hour period ('Fig. 9). As pointed out in Table III the loss in the total tissue activity after 75 hours ranged from to , depending on salinity. This loss of activity was not accounted for by an increase in the media activity, thus the C14 must have been expelled as C14Oo, indicating metabolism of labeled compounds. 951 90- co 85- Z O U 80J CO 75- 25. 20- PROTEIN GO Z) o CO •z.
