Hendrickx \.—Sarcomatous tumors have been observed as prim¬ 
itive lesions in a great number of organs. In many cases they 
have remained isolated and again frequently have become gen¬ 
eralized. There remains an obscure point in their etiology, but 
without allusion to the parasitic or microbian nature, the author 
believes that the nature of the soil (the constitution of the ani¬ 
mal) has much to do with its growth. Still, there are cases 
where the effect of a traumatic action cannot be ignored. The 
following seems to justify this theory. A seven-year-old cow 
receives a violent bruise on the external angle of the ischium, 
which is followed by the formation of an hsematoma. Its 
resorption being very slow, the tumor was opened and treated 
by creolin injections. But, instead of disappearing thus, its 
bottom began to granulate and the spreading tumor increased 
gradually until it became as big as a man’s head. It then forms 
a rounded enormous tumor, very wide at its base and spreading 
with the tissues all round. On its outside there open four ir¬ 
regular fissures or fistulas, from which foetid pus escapes. The 
tumor is not painful and, as proved by the microscope, is of 
sarcomatous nature, belonging to the encephaloid variety. Tak¬ 
ing the condition of the animal in consideration, operation is 
decided upon. A circular incision is made above the base and 
the skin around it dissected to isolate the tumor as much 
as possible. It is then observed that the neoplasm is not en¬ 
tirely subcutaneous, but branches off under the ischio-tibial 
muscles. At any rate by careful dissection it is extracted with 
comparatively very little haemorrhage ; it weighed 16 pounds. 
The broad operated field is then covered with a pad dipped in 
phenicated water and held in place by stitches. During the 
first days, everything seemed to go on very well, but when 
after a month of attentive treatment the wound was consider¬ 
ably reduced, abnormal granulations of bad nature began to 
grow, they resisted all forms of treatment, kept up prolifer¬ 
ating and after a certain length of time the general condition 
of the cow appeared to give way, and, notwithstanding heavy 
feeding, rapid and comple emaciation followed, the animal died. 
At the post-mortem a very great number of sarcomatous enceph¬ 
aloid tumors, from the size of a pea to that of a hen’s egg, 
were found in every parenchymatous organ, lung, liver, spleen, 
kidney. At the seat of the operation a comminuted fracture 
of the external angle of the ischium existed, with a large, loose 
splinter. The author believes that in this case, the visceral 
lesions were developed after the ischial tumor, which had for
