FUNCTIONS X>F THE CEEEBELLUM. 381 



marrow bore a dull,- white aspect, were of greater consist- 

 ence than is natural, and had lost about a quarter of their 

 size ; the nerves arising from them appeared to us also 

 to be in a state of atrophy near their origin" (Larrey, 

 op. cit., p. 207). 



CASE VIII. Another patient was struck by a piece of 

 wood on* the right side of the head. He was found dead a 

 little over three months after the injury. " The right hemi- 

 sphere of the cerebellum was entirely disorganized by an 

 abscess which pervaded its whole substance " (Larrey, op. 

 cit., p. 210). No disturbances of movement were noted. 



CASE IX. Another patient had erysipelas following a 

 fall on the side of the head, and abscess. He lived for three 

 or four months. Five or six weeks after the injury, he had 

 severe pains in the occiput, and, " when standing he could 

 with difficulty only preserve his equilibrium." On post- 

 mortem examination, the deep-seated vessels of the cere- 

 brum were found injected. "We found, in the left lobe 

 of the cerebellum, about three tablespoonfuls of pus of a 

 whitish and gelatinous aspect, which had encroached upon, 

 or rather displaced entirely, the hemisphere of the cerebel- 

 lum ; this purulent substance was enveloped within the pia 

 mater, which had acquired a somewhat firmer consistence, 

 and, as in the subject of the preceding case, assumed a pearly 

 color. The other half of the cerebellum was shrivelled, and 

 the medullary substance forming the arbor vitse was of a 

 grayish color and very dense " (Larrey, op. cit., p. 211). 



The first of these cases was found by Larrey to be asso- 

 ciated with extinction of sexual appetite, and atrophy of the 

 organs of generation. In the first two cases, judging from 

 the results of experiments on animals, there was not enough 

 injury of the cerebellum to necessarily influence the power 

 of coordination. In the last case, there was difficulty in 

 equilibration, but also some paralysis. 



A number of cases, which it is unnecessary to detail 

 fulry, are cited by Wagner, in the Journal de la physiologic,
