course of instruction will be adapted to our increasing wants ; 
and, lastly, that these things will, by their combined influence, 
contribute to and promote the extension of and addition to 
veterinary knowledge. 
Such being the remarkable features presented to my mind by 
a contemplation of the past and a review of the present, we 
have next to consider what are our hopes, our intentions, and 
our duty with regard to the future.

INFLUENZA IN THE HORSE.— HOCK DISEASE. 
[In a private letter from my friend, the Andersonian Veterinary 
Professor at Glasgow, are the following paragraphs. At the 
hazard of being accused by him of breach of confidence, I 
will transcribe them ; and if his pen — and I know but few 
that are abler— is employed in lashing me for such transgression, 
still the readers of The Veterinarian will be no losers. — Y.] 
“ In the month of June we had another kind of influenza 
here. It was the same that vou had in London. The horse was 
fevered — the eyelids, muzzle, and legs, anasarcous ; the pulse 
always small and weak , and seldom beating more than 50, some- 
times not exceeding 30. It seemed to be confined to Glasgow 
and its neighbourhood. Only one death in my practice. Se- 
veral horses had it twice. In some it was combined with bron- 
chitis. These were largely bled, as were many of the others. 
More than fifty were not bled. They got aloes in two-drachm 
doses.” 
(i In the discussion on the hock-joint, I think that Mr. Spooner 
is mistaken. Since I read his paper in 1830, I have seen this 
supposed ulceration oftener than I can tell. I do not remember 
to have seen an astragalus without it. You will also find that 
the wedge-like ridge of the tibia never reaches to the bottom of 
the groove in which it works. Friction of the astragular ridges, 
as alluded to by Mr. Dick, is not very rare. I have several 
preparations in which they and the tibia are much worn down, 
and polished, like ivory. The symptoms are not obscure. There 
are always lameness and bursal enlargement. I have a hock 
that belonged to a horse, in whom the bones could be heard 
grinding upon each other/'
