It went on falling to 0.052 per cent, and never even regained the 

 initial value. 



In a normal cat morphine and insulin were administered at 

 the same time. A marked hyperglycemia developed, the blood 

 sugar sinking from 0.13 per cent, to 0.033 per cent. A similar 

 experiment was performed on a cat whose right adrenal had been 

 excised and the medulla of the left destroyed by a drill, the left 

 gland being then denervated, 19 days before the experiment. 

 The result on the blood sugar was the same as in the normal cat, 

 the percentage falling from 0.103 to 0.040, with no attempt at 

 return towards the initial value. The general symptoms were 

 the same in the two cats, which presented a characteristic mix- 

 ture of hyperexcitation (due to the morphine) and depression. 

 In both animals the paradoxical pupil reaction was strongly 

 marked in the left eye throughout the experiment (the left su- 

 perior cervical ganglion had been previously excised), and quite 

 as pronounced in the cat whose epinephrin secretion had been 

 abolished as in the normal cat. The usual hyperthermia pro- 

 duced by morphine in cats was absent in both cases. Except for 

 a slight temporary rise in the animal with the adrenal operation, 

 the rectal temperature went on falling throughout the experiment. 

 In this respect the insulin apparently caused the morphinized 

 cats to behave like dogs or rabbits.

The relation between chronic irritation of peritoneal mesothelium 

 and the formation of adhesions. 



By R. S. CUNNINGHAM. 



[From the Department of Anatomy, Johns Hopkins University,

During a systematic investigation of the normal and patho- 

 logical reactions of the peritoneal mesothelium, certain rather 

 surprising facts have been revealed which are interesting because 

 of their bearing on the question of adhesions. 



Elsewhere 1 experiments have been reported in which rats re-
