Autopsy. — On the body of the first lumbar vertebra was found a hard 

 spherical tumour, the size of an egg, measuring two and a quarter 

 inches from before backwards, and two inches across. It chiefly occu- 

 pied the right part of the vertebra, the transverse process of which it 

 entirely surrounded, and was formed of two lobes, one developed on the 

 right surface of the body of the vertebra, the other (which covered the 

 inferior surface from one transverse process to the other) extended 

 beyond the left transverse process, above which on the vertebra a large 

 osteophyte was visible. The upper lobe of this tumour was in contact 

 with the last dorsal vertebra, which it had thrust backward and some- 

 what to one side. Its low^er lobe covered a portion of the lower 

 surface of the second lumbar vertebra. 



On exposing the spinal cord in the lumbo-sacral region the cha-

racters and relationships of the tumour could be clearly made out. It 

 formed in the spinal canal a distinctly marked prominence about one 

 and a quarter inches in length, above which the spinal cord was com- 

 pressed and reduced to half its normal thickness. Its consistence 

 varied according to the point chosen : the part within the neural canal 

 was relatively soft, yielded to pressure, and was easily divided with the 

 point of the bistoury, but towards the centre the appearances were 

 those of bony tissue. 



On microscopic examination the tumour appeared formed _ of 

 fusiform cells and tracts of osteoid tissue, pierced with branching 

 cavities provided with canaliculi, and offering the appearance of osteo- 

 blasts.

10. Eleven-year-old gelding. Entered hospital on the i8th July, 

 1898. Four months before the eyelids of the right eye were found to 

 be glued together each morning by muco-pus. A veterinary surgeon 

 who was consulted thought this due to simple conjunctivitis, and 

 prescribed boric acid lotions. The discharge continued, the lower 

 eyelid became thickened, vegetations developed on the conjunctiva, 

 thrusting aside the eyelid and soon extending beyond the free margin .
