and bars opened or preserved, the frog pared or left, the hoof rasped 
thinner or left untouched, the seat of corns pared out or not;—how 
the shoe should be fitted, whether it should be longer than the 
points of the heels or not, according to the degree of obliquity of the 
foot—whether the shoe should be seated even throughout the whole 
circumference, or be sprung at one or both heels—the kind of feet 
that require a bar shoe ; in the crust, whether the nails should be 
driven high or low, that is, more or less obliquely—whether the 
toe will bear shortening or the heels lowered :—all this an intel¬ 
ligent farrier can tell with tolerable correctness at a glance ; and if 
he can, knowing nothing of the structure of the parts, why should 
not a veterinary surgeon know it also 1 There is no mystery in all 
this; it is perfectly easy when properly taught. Let a teacher 
demonstrate these points, and examine the student by putting a foot 
before him, and, if he is wrong in his idea, let it be pointed out : 
plenty of feet can always be procured from the slaughterers, and a 
few lessons of this description would soon make an important altera¬ 
tion in this necessary branch of our art. 
In my next communication I shall inquire more particularly into 
the nature and results of Mr. Gloag’s experiments, and endeavour 
to trace how far they agree with the facts as daily exemplified in 
the forge and oil the road.

MAGENDIE’S EXPERIMENTS—THE INFLUENZA IN 
HORSES. 
By Edw. Mayhew, M.R.C.V.S. 
SINCE I last had the pleasure of addressing you, I have received 
a letter inviting m£ to meet M. Magendie at the house of a well- 
known physician. It would have been my wish to seize any 
opportunity of shewing courtesy to a foreigner; and any little 
information I may possess is, in my eyes, only a trust held for the 
general benefit of mankind. I have no secrets, and desire to prac¬ 
tise no reserve; but there are individuals towards whom I cannot 
stoop to pretend respect. M. Magendie has made himself noto¬ 
rious by his cruelties. He has lived amid the cries of the animals 
he has, under the sanction of science, tortured. Vivisection has 
been the life-pursuit of the man, and his deeds have taught
