rhage ; two cases of paralysis, with atrophy of one hemi 

 sphere of the cerebrum and one hemisphere of the cerebel- 

 lum ; nine indefinitely described cases, with paralysis ; three 

 cases of abscess, with paralysis ; one case of cyst and one of 

 abscess, with paralysis ; fifteen cases of tumor, with paraly- 

 sis ; seven cases, associated with disease of the cerebrum and 

 paralysis ; nine very indefinitely described cases, associated 

 with convulsions. Of the remaining cases observed by An- 

 dral, we can discard one, with hemiplegia and convulsions ; 

 one, with hemiplegia and subsequent haemorrhage ; one, 

 with hemiplegia ; one case of cyst, with paralysis and con- 

 vulsions ; one, of tubercle, with hemiplegia. We can also 

 discard one case of five small tubercles in one hemisphere 

 of the cerebellum ; one, of a tuberculous mass, the size of a 

 hazel-nut, on one side ; one, of a cyst, the size of a hazel- 

 nut, on one side. These last cases do not present sufficient 

 destruction of the cerebellar substance to lead us to expect 

 any disorder in the movements. 



Thus far we have discarded eighty-five cases, leaving 

 eight to be analyzed. Of these eight cases, in five, it is 

 simply stated that the movements were unaffected, and that 

 " one of the lateral lobes of the cerebellum was the seat of 

 abscess " (Andral, op. cit., p. 500). In view of this bare state- 

 ment, and the fact that, in animals, recovery of coordinating 

 power takes place when half of the cerebellum has been 

 removed, we may throw out these cases as incomplete. It 

 must be remembered that the abscesses were probably of 

 slow development ; and if they did not destroy a sufficiently 

 large portion of the cerebellum to influence the coordinating 

 power permanently, it is not probable that the functions of 

 this organ would be at all affected, as there would be no 

 shock, as in the sudden removal of substance by an operation. 



We are thus reduced to three cases ; and in all of these, 

 the movements were more or less affected. These cases we 

 will now study as closely as is possible from the details given.
