matter of impossibility. Their presence gives rise to symp- 

 toms \\-hich vary in accordance with the part of the brain 

 substance upon which they cause pressure. Adenoma and 

 sarcoma have each been recorded. 



In the Journal of Comparative Pathology, vol. x., p. 75, Professor 

 Penbertby records a case of tumour about the size of a walnut in the 

 right lateral ventricle of an aged bulldog, and attached only to the 

 vessels of the plexus choroides. This, upon examination by Professor 

 JVIcFadyean, proved to be an adenoma. The patient appeared silly, 

 could see fairly well, but was somewhat deaf. The dog was dull and 

 listless, the pupils were dilated, and, although the appetite was good, the 

 body was emaciated. These symptoms came on suddenly, and were 

 only noticed about a fortnight before admission into hospital. The 

 patient was destroyed. In a second case, translated for the Veterinary 

 Ncvjs and Bulletiti (November 12, 1904) from Annates Beiges, AI. Hebraut 

 records a case occurring in a dog of eight years of age, which had for two 

 months been affected with cerebral symptoms, characterized by difficulty 

 in locomotion. The patient had difficulty in rising, and staggered on his 

 hind-quarters, catching up one hind-leg suddenly and then falling lame 

 on it, dragging it along. He ran up against obstacles, and did not 

 appear to see them ; knee jerks were exaggerated. Later the dog became 

 partly paralyzed, and kept turning to the right. The patient was 

 destroyed, and a post-mortem revealed a small hard tumour, the size of a 

 small pea, on the right side of the base of the cerebellum, and adherent 

 to the pia mater. On microscopical examination it proved to be a 

 sarcoma.
