mortem examination, " in place of the cerebellum there was 

 a cellular membrane, gelatiniform, semicircular, from eigh- 

 teen to twenty lines in its transverse diameter." There was 

 no trace of the pons Yarolii. Combette states that Alex- 

 andrine Labrosse was able to walk for several years, always, 

 it is true, in an uncertain manner ; later, her legs became 

 more and more feeble, and finally she ceased to be able to 

 sustain her weight. She had the habit of masturbation. Com- 

 bette further states that this observation is not in accord 

 "with the experiments of Flourens, which tend to show 

 that the cerebellum is the regulator of movements." The 

 encephalon was also examined by Guillot, who noted ab- 

 sence of the cerebellum and of the pons. 



This case is somewhat imperfect, as it was not seen by 

 Combette until the patient had kept the bed for three 

 months. By some writers, it is quoted in favor of, and by 

 some, in opposition to the view that the cerebellum coordi- 

 nates the muscular movements. It was not a case of simple 

 disease of the cerebellum, as the pons and the posterior pe- 

 duncles were also absent. It was noted, before the case was 

 seen by Combette, that the patient walked in an uncertain 

 manner and often fell. 



Several cases of injury of the cerebellum are reported by 

 Larrey. 1 



CASE YII. One case is described, in which the patient 

 was struck by a ball from a blunderbuss, which grazed the 

 occipital protuberances. There was no disturbance of move- 

 ment. The patient died on the thirty-ninth day, in opisthot- 

 onos. On post-mortem examination, "the occipital bone 

 had sustained a considerable loss of substance ; the slit into 

 the dura mater, to which we have alluded, corresponded to 

 the centre of the right lobe of the cerebellum, which was 

 sunk downward and was of a yellowish color, but free from 

 suppuration or effusion. The medulla oblongata and spinal
