THE SPINAL CORD AND CEREBELLUM 135 



removal of the cerebellum there is any loss of power 

 in the heart corresponding to that so clearly marked 

 in the case of the voluntary muscles. 



In another case* the cerebellum of a bitch was 

 completely removed. Four months after the operation 

 the animal gave signs of 'heat,' was impregnated, 

 and ' was allowed to survive until she had whelped, 

 nearly a year after.' Parturition was regular and the 

 maternal instincts normal. The general health of 

 the animal was good, and she had increased in 

 weight. A small fragment of the right lobe of the 

 cerebellum alone remained after death, which was 

 caused by the administration of chloroform. The 

 motor mechanism was more seriously affected than in 

 the previous cases, the animal being only able to 

 move by * butting forward,' but there were few, if any, 

 signs of inflammation. 



It will probably be admitted that the evidence in 

 the first case is distinctly more favourable to Luciani's 

 view than to that of Perrier. As regards the second 

 case, there is, perhaps, more room for doubt. It is 

 true, on the one hand, that the nutritive condition of 

 the animal was good, that it had even improved, and 

 Ferrier assumes at once on the strength of this fact 

 that the evidence of malnutrition in the first case may 

 be entirely disregarded. With respect to this, how- 

 ever, certain matters deserve further consideration. 

 We have spoken of the cerebellum as a centre for the 

 increase of impulses, but are we sure that it is the
