206 THE DISEASES OF THE DOG. 



head bathed constantly with cold water, leeches may be 

 applied to it, and in cases taken early, even small doses 

 of Liq. Ammonias given. The injury should receive the 

 most careful attention, it should be fully explored with a 

 view to the detection of fracture and removal of the de- 

 pressed portions with the elevator and trephine, sec. art. It 

 should then be treated antiseptically and so as to control any 

 tendency to inflammation. The supervention of Encepha- 

 litis will be indicated by excitement, and convulsions, 

 followed at a short interval by coma and paralysis, 

 according as the meninges and the brain-substance are 

 gradually involved. An interesting case of injury to the 

 brain and its membranes is recorded in the ' Veterinarian/ 

 1843, from M. Leblane. Although given in extenso by 

 Touatt and Hill it will bear summary here. Autopsy 

 showed that the meninges of the left cerebral lobe were 

 not thicker than one membrane usually is, and the corre- 

 sponding brain-substance seemed firmer than normal. The 

 cerebral fissures and vessels of the left lobe were small. 

 The patient was three years old and subject to epilepsy. 

 His final fit was followed by a loss of the usual lively 

 appearance of the eye, and the eyelids being often closed 

 and the animal spiritless, drowsy, and subject to clonic 

 spasms of the muscles of the head and chest. He always 

 lay on his left side, and in walking he exhibited a marked 

 propensity to turn to the left. He latterly gyrated to the 

 left and kept walking until worn out. He continued his 

 course regardless of obstacles, and at last he seemed to 

 simply turn as on a pivot to the left. He became very 

 thin. Messrs. Gowing ( f Veterinarian,' 1870) relate a case 

 of effusion of pus into the left arachnoid sac, probably the 

 result of injury. The dura mater was diseased and there 

 was a recent haemorrhagic clot in the left corpus striatum . 

 The patient had lost his sight, both pupils being dilated ; 

 he advanced cautiously, inclining neither to right nor left, 

 and was obedient to his master's call. He slightly 

 recovered use of the left eye. He fell somewhat suddenly 

 on the left side after this improvement, and the muscles 

 of his neck became rigid, and his nose pointing upwards.
