LARGE SYNOVIAL SHEATH IN A COW’S THIGH OPENED. 213 
think the cavity inside has almost grown up, and united to its sides. 
The tumour is in a great measure on the outside of the hock, as 
when she moves about, it slips to that side. Apply occasionally 
some of the ung. hyd. bichlorid. 
13/A.—This morning I found the hock swelled a little, and the 
part where the ointment had been rubbed on was covered with 
blisters. To be left alone for the present. 
1 6th .—Rubbed a little more of the ointment on, since the effect 
of the last has subsided. Tumour less. Took the bar off the shoe, 
and had the heels merely thickened. 
21th .—Tumour a good deal less, and the wounds healed up; 
and she has been out at grass for ten days. By the occasional use 
of the ung. hyd. bichlor. during the following month, the tumours 
became nearly reduced, and in the course of time natural. 
I recollect that, some years ago, a valuable hunter, the property 
of D. Poole, Esq., of Marbury Hall, received a severe cut on the 
point of the hock, clean down to the tendon, which got well in the 
course of three weeks, without any untoward symptom.

been condemned by one of the inspectors of the Mutual Cattle 
Insurance Company, in consequence of her having a large tumour 
on the front of the thigh, brought on, it was said, by her galloping 
about in June, 1847. On the 15th of March, 1848,1 was requested 
to see her, and operate on her. 
j Examination .—The tumour is as large as a man’s head, and is 
situated at the front and sides of the upper part of the near tibia, 
and no doubt is a bursa or synovial sheath. The owner was de¬ 
termined to have it opened, and so to kill or cure, as she cost but 
ten shillings. 
I accordingly had her cast, and with a penknife I made incisions 
at the upper and lower part of the tumour into the sac. At first, a 
quantity of liquid synovia issued out of the wounds, and by using 
greater pressure several quarts of coagulated synovia were squeezed 
out. I introduced my finger into the wound, and I could dis¬ 
tinctly feel some tendons and masses of synovia: the latter I broke
