In the following experiments 1 cubic centimeter of autolyzed 

 material or of bacterial suspensions which had been incubated 

 long enough to allow of self-digestion, was added to 5 cc. of 

 purified egg albumin, to Witte's peptone and to purified proteose. 

 Biuret tests were made after definite periods of incubation at 

 37°C. In each experiment the original biuret reaction is the 

 same for all of the flasks including the control.
