CARCINOMA-MELANOSIS. 459 



patient was feverish, with the testicles drawn up, and one 

 enlarged ; he was dull ; but there was no appearance of acute 

 inflammation. The groom, a very intelligent man, was 

 doubtful whether a cancerous tumour did not exist, as he 

 had seen the same symptoms in another horse, who died, and 

 was opened by Mr. Baker, and found to contain a tumour 

 weighing eighty-four pounds ; but there was no bloody urine. 

 Mr. Anderson thought at first he had a case of scrotal hernia. 

 On the 25th he was convalescent, and had got into tolerably 

 good condition. On the 4th February he was attacked with 

 hsematuria. On the hand being passed over the loins, he 

 crouched to the ground, and there was a stiffness about the 

 loins, and he constantly appeared to be in the attitude of 

 staling. Mr. Anderson now thought the case was nephritis. 

 He was bled and clystered, and had fomentations to the loins, 

 and mustard poultices and astringent medicine. — 12th, Still 

 very feverish, and great quantities of coagulated blood have 

 been discharged. — 13th, Hemorrhage continues; but the 

 inflammation is subdued. — 18th, Immense quantities of 

 blood coming away. Ordered sugar of lead, catechu, and 

 zinc internally. — 22d, Has passed a great deal of blood since 

 last visit, and at present it is dropping from him. Testes drawn 

 up. Mr. Anderson had a consultation with Mr. Rowland, 

 V.S., Oton, Notts. They differed in opinion as to the nature 

 and treatment of the disease, though both agreed that it 

 originated in the kidneys ; " but neither of us anticipated the 

 existence of such a voluminous tumour.^^ — On the 23d the 

 horse died. A tumour was found attached to the spleen, 

 left kidney, and super-renal gland. The right kidney and 

 the viscera were all healthy. The tumour weighed one 

 hundred and two pounds ; measured sixty-eight inches in 

 circumference — including the spleen, seventy-three. Mr. 

 Anderson sent off the tumour the same day to Mr. Youatt for 

 examination, remarking only, further, that " two things are 

 certain — previous inflammation, and death by excessive 

 hemorrhage.^' 



Mr. Youatt examined the substance, and found it to con- 

 sist of " a conglomeration of carcinomatous tumourSy rising
