656 INTRACELLULAR GROWTH OF BACTERIOPHAGES. I 



When 5-methyltryptophan replaced cyanide as the metabolic inhibitor, 

 similar results were obtained. The curves were, however, displaced several 

 minutes to the left on the time axis. 



The results are compared with Latar jet's (16) data on x-radiation of infected 

 bacteria and with Foster's data (18) concerning the effect of proflavine on in- 

 fected bacteria. Essential agreement with both is apparent.
