Together with Fritz Koch, I2 have made a series of examinations with the object of ascertaining the degree of intra-ocular tension in cases of diabetic coma and of hypoglycemia after insulin injection. Of eight cases of diabetic coma, we found great reduction of the intra-ocular tension in six, while in two cases the tension was normal. Therefore when Heine3 says that "this great reduction in tension seems up to the present to have been observed only in cases of typical diabetic coma, and that
