Side-view of the scheme of the cortex 

 of the brain of a dog. The ciphers in- 

 dicate the squares, which were successi- 

 vely stimulated with the induction cur- 

 rent Wheu 15 and 16 are stimulated 

 we see deeper inspiration or less extensive 

 expiration, or quicker superficial respi- 

 ration.

Side-view of the scheme of dog's 

 brain, (as above). 



Side-view of the brain of a dog. If 

 the place, indicated by a circle, is stimu- 

 lated with *n induction current, the in- 

 spiration becomes deeper, the respiration 

 quicker, the expiration less extensive and 

 the pulsation quicker. After the stimula- 

 tion the expiration is lengthened, tlie 

 pulsation slower than before. By stimu- 

 lation «ith a moderately strong induction- 

 current we find stretch-movements of the 

 fore leg and lifting np of the head.
