DISEASES OF THE NERVOUS SYSTEM. 27 1 



a circular direction he turned aside, but always to the left. 

 The nearer he approached his end the smaller were the cir- 

 cles that he took, and, in the latter period of his existence, he 

 did little more than turn, as he would on a pivot. When the 

 time arrived that he could walk no more, he used to lay him- 

 self down on his left side, or, if we put him on the right side, 

 he turned his head always to the left. During the whole of 

 the case I did not observe any very evident signs of palsy. 

 For a considerable peripd he had eaten with appetite ; but 

 nevertheless he grew thin from day to day, although he was 

 too well fed by the owners, who continually crammed him 

 with food, notwithstanding my efforts to prevent it. 



" At the post-mortem examination I found a remarkable 

 thickening of the meninges on almost the whole of the left 

 lobe of the brain. 



" The dura mater, the two layers of the arachnoid mem- 

 brane and the pia mater, did not constitute more than one mem- 

 brane of the usual thickness, and presented a somewhat yel- 

 low covering. The cerebral substance of the left lobe ap- 

 peared to be a little firmer than that of the right lobe. 



The fissures of the cerebral circumvolutions were here 

 much less deep than those of the other side. The bloodves- 

 sels which ran in the fissures were of smaller size, and in some 

 places could scarcely be discovered." 



The following interesting case, recorded by Messrs. Gowing 

 and Son, in the " Veterinarian " for May, 1870, may be classed 

 under the head of meningeal disease : 



" On the 2d inst, our attendance was requested at Brook 

 Street, Grosvenor Square, in respect of a white terrier 

 dog, eighteen months old. The history of the case is as 

 follows : 



" The owner stated that the dog had been brought from 

 Oxford, and that he had recently lost his vision. On exami- 

 nation it was found that the pupils of both eyes were some- 

 what dilated, and therei was no power of recognizing objects ; 

 the other special senses did not appear to be interfered with,
