A CASK OF SARCOMATOUS DISEASE. I07 



tissue ; both forms, however, are always associated in the same subject. 

 The tissue of these new growths is pale grey, without marbling, is 

 firmer and denser than that of other sarcomata, and is composed ex- 

 clusively of fusiform cells. Round-cells never occur. 



Such were not the clinical or anatomical features of the disease in 

 our patient. The skin was altogether unaffected : the tumours were 

 dispersed throughout the subcutaneous and intra-muscular connective 

 tissue ; only a few adhered to the skin, and even they did not penetrate 

 it. Moreover post-mortem examination showed much more extensive 

 visceral lesions than we had anticipated. The visceral lesions pre- 

 -ceded those in the subcutaneous connective tissue, but we were unable 

 to make out any close connection between the subcutaneous and the 

 visceral tumours from the point of view of their origin. No vascular 

 lesions existed to explain the generalisation. 



The patient died at the commencement of the sixth week after 

 admission to hospital. I wish to remind you of its history. The 

 report of the post-inortciit examination leaves no room for wonder at 

 the animal's death. 



A Dutch gelding, about twelve years old, in fairly good condition. 

 Sent to the College on account of subcutaneous swellings in different 

 regions. The largest was situated on the right side of the chest, 

 opposite the fourth, fifth, and sixth ribs, a little above the line of the 

 elbow. Hemispherical in form, it measured nearly six inches in 

 diameter. Another of about the same size lay immediately in front of 

 the cervical angle of the scapula. A third, as large as a fowl's eg^> 

 was noted about halfway up the left side of the chest, opposite the 

 sixth rib. At the lowest part of the same side of the chest, opposite 

 the twelfth rib, was a nodule the size of a nut. On the left side again, 

 over the thirteenth rib, was a tumour as large as a pigeon's egg. All 

 were practically of the same character, being firm, slightly elastic, 

 painless, sharply defined, moveable under the skin and over the sub- 

 jacent parts, or in cases slightly adherent to the latter. 



The temperature, respiration, and circulation were normal. The 

 urine showed considerable sediment, consisting largely of carbonate 

 and phosphate of lime, but contained no albumen, sugar, or bile pig- 

 ments. There \vas no change in the proportion of urea. 



The blood was normal. The number of blood-corpuscles was found 

 to be as follows : 



Red corpuscles . . . 5,602,875 per cubic millimetre. 



White corpuscles . . 5864 ,, ,, 



Proportion . . . . i to 955.
