result in cats, and that it does so in dogs only because of a 

 different anatomical arrangement. In their opinion, extirpa- 

 tion or ligature of the glands in dogs necessitates damage to 

 nerve fibres, while in cats it may not. 

 According to our experiments there is no such difference

 results, indeed, entirely confirm those of Elliott and apply 

 equally to dogs, cats, and rabbits. We have usually obtained 

 quite satisfactory positive results by simply clamping and 

 unclamping the adrenal veins. Moreover, all necessary dissec-

 the control experiment was performed (see Figs. 49, 50). 



Fig. 51 shows that the results in the cat were similar to those 

 obtained with the dog.
