quite as many cases of lameness as spavins; and the know- 
ledge of this fact enables me at once to decide on the true seat 
of obscure lameness of the hind extremities ; and I would ven- 
ture, at any time, to wager three to one, that if the animal die, 
or is killed, the post-mortem examination would prove my 
assertion. 
I am sorry to find my friend, Mr. C. Spooner, has stated 
that “ the cases of disease of the articulation between the tibia 
and astragalus are few indeed and I can only account for this 
opinion being entertained by such an acute observer and excel- 
lent anatomist, by supposing that it is in country practice where 
such cases most abound. Every one must be aware of the great 
uncertainty that attends the treatment of spavins. Why is this 
the case ? Because, in the curable cases, there is only simple 
exostosis, while in the others there is also ulceration in the articu- 
lating surfaces of the joint. I could enlarge on this subject as 
well as on that of firing, 8tc., but must, at present, content 
myself with the few remarks that I have thus hastily thrown 
together. 
[We beg leave to tender our thanks to Mr. W. C. Spooner 
for his kind and valuable present of the specimen to which he 
alludes in this Essay. It came too late for us by any possibility 
to obtain an engraving of it for the present number ; but at no 
distant period it shall appear in The Veterinarian. It will 
be seen that there could be no doubt as to the friction between 
these bones being the cause of lameness in this instance, and we 
are disposed to go very far with our friend as to its being a fre- 
quent cause. — Y.]

The words Icterus and Jaundice do not properly designate any 
particular disease, but a symptom of many diseases, the seat of 
which is variable. All who are concerned in the practice of 
medicine well know this. The symptom is a yellow discolora- 
tion of the skin and the mucous membranes, of greater or less 
intensity. I have no intention of writing a monograph of this 
stain of the integument, but will confine myself to .jaundice in 
the dog, of which in my infirmary I have had opportunity to 
study numerous cases.
