macerated, or other ways prepared, and see where the groove made 
by the tendon runs, and compare with a hock that has no deposit 
on it, they will, I think, see it is so. For favorable results I think 
we must have complete anchylosis of the cuneiforms to the head 
of the metatarsal; for I think we will not have a deposit 
large enough to warrant an operation, without we have ulcerations 
on the articular surfaces of the metatarsal and small bones. 
I think if you look at your specimens, you will find it is so. 
I think when we are satisfied we have complete anchylosis of 
those bones and the lameness is due to pressure of the tendon on 
the periosteum, we will have a successful operation ; while if this 
is not the case, we will not. I also think, the lower down and the 
nearer the attachment of the tendon to the small cuneiform bone 
we make our incision and division of the tendon, the better our 
success, while the higher up and the more towards the forward 
portion of the hock, or, as I might say, the nearer the capsular 
covering of the tibio tarsal articulation we get, the more chances 
of synovitis and a failure. 
Hoping to have others express their views on this subject so to 
save other favorite steppers. 
I am yours, &c.,

PROGRAMME AND RESULTS OF EXPERIMENTS 
UPON VACCINATION OF ANTHRAX AT THE FARM OF POUILLY-LE- 
FORT. 
By M. Pasteur. 
The Society of Agriculture of Melun having offered to M. 
Pasteur, to practically test the value of the experiments made by 
him and his assistants relating to anthrax, the following programme 
of experiments relating to preventive vaccination was agreed 
upon: 
1st. The Agricultural Society of Melun places at the disposi¬ 
tion of Mr. Pasteur sixty sheep.
