PARTURIENT APOTLEXY IN THE COW. 
will suppose a client has employed us to give an opinion as to 
soundness, and the animal is believed to be sound, and our 
client purchases him : the horse, in all probability, is shod 
in our forge, and in the course of a few weeks the animal goes 
lame from some cause or other, which, as a matter of course, 
has the effect of ruffling the temper of our client, who either 
complains that the horse has been improperly shod or that 
some mistake had taken place in the examination. In either 
case it is an unpleasant position for a veterinary surgeon to 
be placed in. 
After a careful examination of the limb we come to the 
conclusion in our own mind that the navicular joint has suf¬ 
fered, although we hesitate to advance so much, as the owner 
will at once jump to the conclusion that the case is of long 
standing, and that an oversight had occurred at the examina¬ 
tion as to soundness. It is sometimes difficult to make a client 
believe the disease in question can be, and often is, produced 
in a moment, especially if he learns that the same animal has 
at any former period been the subject of lameness in the 
same foot. I repeat, it is sometimes difficult to make your 
client believe the truth ; there are always, and everywhere, 
kind-hearted (?) persons ever ready and willing to put in a 
good word for us, as it frequently favours them with an 
opportunity of advancing their own opinions to the detriment 
of ours. 
Navicularthritis may be produced in many ways, viz., 
over-jumping, a slip after a jump, a fall, a jar of any 
sort, but more particularly, constant concussion upon irre¬ 
gular and hard surfaces. Before, however, we speak espe¬ 
cially of the causes and symptoms of this disease, it may be 
wise to take a glance at its history. It is both interesting 
and advantageous to do so, as the disease known as navicular¬ 
thritis in the present day, was supposed to be a different one 
altogether, at the beginning of the present century.

Case 1 . —On the 11th of November, 1863, I was called
