 indicate certain abnormal changes in the tissues of the i)uppies fed boiled milk. 



An effort was made to determine if injufious substances are developed in 

 tlif process of heating. Milk heated for 150 minutes over a naked flame 

 showed the presence of (t.tn2t; ]ht crut of anmiouia. The same process resulted
