4o EXAMINATION OF HORSES 
reticular tissue, which immediately covers the sheath of 
the extensor tendons. To the latter they are connected. 
firmly, to the skin but loosely. The consistence of their 
contents varies very much, but they seldom communicate, 
with the articular-synovial cavity. If nothing else, they 
are unsightly, being sometimes-as large as cricket-balls, 
or larger. A horse bought with such a tumour would 
have to be taken for better for worse, because, if an un- 
soundness, they are unmistakably apparent. Sometimes 
you will see more than one on the same animal, just as 
you will frequently see several enlarged bursa on the 
same animal. These ganglions impede mobility or not, 
according to their size and position. 
You must remember we are examining the front part 
of the fore leg, and having finished the knee pass our 
hand over the front part of the.cannon bone down to the 
front of the fetlock joint. The bone.all this way is nearly 
subcutaneous, the tendon of the extensor of the foot only 
passing obliquely in front of it. Practically, it is subcu-; 
taneous, so that here we have only the skin, the front of 
the cannon bone, and the tendon, just mentioned, to 
examine; and I might also have said that practically 
we can pass over this part without a thought, as we seldom 
find it affected in any way. 
The front part of the pastern joint comes next. This 
and the pasterns are so intimately connected with, and 
influenced by, the foot, that I shall here make a wide 
digression, and describe all the parts beneath the fetlock 
-joint together.
