✦ Synopsis

FOUR FIQTJRES

I t has been stated that frog muscles in good condition have a low oxygen consumption, whereas those in poor condition show a high rate of oxygen absorption. Apparently, the death of muscle cells involves a, marked acceleration of respiratory metabolism (Fenn, '30). Similar spontaneous increases in the rate of oxygen consumption of surviving frog skin have been reported by Adolph (,29). In connection with these observations, it would be interesting to know whether or not the same phenomenon is exhibited by other tissues. I n the case of the dogfish lateral line nerve Fenn ('27) found that the oxygen consumption was relatively constant during the first 10 or 12 hours following removal of the body, after which the rate began to increase rapidly. This finding was confirmed by Root ( '32). I n this paper an attempt has been made to analyze the factors concerned.
