CANCER OF THE TESTICLE — UNSUCCESSFUL ATTEMPT TO INOCULATE. 407 



where these tracts were of some thickness, they contained hnes of 

 epitheHal cells. 



With the owner's consent an attempt was made immediately after 

 operation to inoculate with the new growth on the left side of the neck. 

 The skin, having been shaved and disinfected, was incised for a distance 

 of one inch, and a small pocket formed by blunt dissection, into which 

 a fragment of the tumour, about three eighths of an inch square, was 

 introduced. The skin was united with two sutures and covered with 

 collodion, protected by a fragment of taffeta. Healing occurred by first 

 intention. The trifling swelling which formed disappeared in a few days, 

 leaving an indurated patch, which finally became entirely absorbed. 



The patient left hospital on the i6th February, and returned to 

 work a few days later. At first it was brought back weekly, and later 

 once a month. In spite of hard daily work, and the fact that the 

 growth under the lumbar vertebrae increased in size, the animal's con- 

 dition markedly improved for several months, and work was continued 

 without interruption until the 3rd November. 



On that day the animal was brought for examination on account of 

 loss of strength and appetite. It had worked as usual on the previous 

 day. The symptoms were those common to all wasting diseases : the 

 conjunctiva was very pale, the pulse small, the circulation and respira- 

 tion markedly accelerated, the temperature 38*9° C. Auscultation of 

 the heart revealed a systolic murmur. On manipulating the abdomen 

 peritoneal exudate was recognised. The sublumbar tumour had 

 become enormous. The condition being regarded as due to gene- 

 ralisation of the cancer no treatment could be advised. 



The animal returned home, and died during the night. Next day 

 the cadaver was sent to us for examination. The abdominal cavity 

 contained a large amount of blood-stained exudate, though the large 

 vessels were normal. The intestines appeared healthy. The upper 

 part of the right spermatic cord was ver}' large and moniliform (with 

 expansions and contractions, like a string of beads) ; it exhibited a 

 chain of new growths, varying in size between that of a hazel-nut and 

 a walnut, and extending as far as the sublumbar tumour. The latter 

 was sixteen inches in length by ten in breadth, and showed numerous 

 rounded projections, some as large as an apple. It weighed sixteen 

 and a half pounds. Pyramidal in form, its base partly obstructed the 

 anterior opening of the pelvis ; its summit, which was slightly inclined 

 towards the right, was in contact with the corresponding kidney ; its 

 upper surface adhered to the sublumbar region; its inferior was 

 ulcerated, and showed an irregular tear with ecchymosed margins, 

 from which the bleeding had occurred. In front of the tumour the 

 right ureter was dilated ; the walls of that portion contained within 

 the tumour were hardened and thickened, while their lumen was 

 considerably diminished ; the right kidney was slightly dilated. The 

 left ureter was obliterated, and the corresponding kidney showed 

 lesions of hydronephrosis. No secondary tumours were found in any 

 of the viscera.
