typical symptoms of iodism prominent. The dogs were killed by 

 bleeding from the carotids under ether anesthesia, the organs re- 

 moved in the usual manner, hashed, divided into convenient por- 

 tions, mixed with seven parts of saline and allowed to undergo 

 autolysis at 37°C. in the presence of toluol. Kjeldahl determina- 

 tions were made on the half saturated zinc sulphate filtrate and on 

 the acidified saturated zinc sulphate filtrate. 



In all cases the rate of autolysis was found to be considerably 

 faster than that of organs taken from normal dogs. The increased 

 rate of autolysis was noticeable particularly in the liver and kid- 

 neys, and especially during the first twenty four hours.

Dogs were thyroidectomized. Typical symptoms of thyroid 

 removal, appearing at variable intervals after the operation, were 

 prominent in all the animals. From five to ten days after thyroid- 

 ectomy, the dogs were killed by bleeding from the carotids 

 under ether anesthesia, the organs removed, hashed, divided into 

 convenient quantities, mixed with seven parts of saline and allowed 

 to undergo autolysis at 37°C. in the presence of toluol. Kjeldahl 

 determinations were made on the half saturated zinc sulphate 

 filtrate and on the acidified saturated zinc sulphate filtrate. 



In all cases the rate of autolysis of the organs from thyroid- 

 ectomized dogs was slower than that of the organs from control 

 animals. The decreased rate of autolysis was noticeable particu- 

 larly in the liver and kidneys, and especially during the first 

 twenty four hours.
