OF THE ROYAL VETERINARY SCHOOL AT LYONS, 
DURING THE SCHOLASTIC YEAR 1834-5.

Founder. — We recorded a certain number of cases of 
founder in the last year, and which we attributed to the heat of 
the season, and the heat and hardness of the soil. The same 
affection has reappeared this year in a great many horses, doubt- 
less from the influence of the same causes in some of them, but 
in others being evident instances of relapse. In almost all of 
them it attacked the four feet at once. Although some writers 
have stated that founder is most serious and obstinate when it 
attacks the hind feet, we have always seen the pain and inflam- 
mation cease comparatively quickly in these feet, while it has 
continued longer, and in many instances has become incu- 
rable, in the fore feet. However, after the disappearance of 
inflammation of the laminae in the hind feet we have seen a very 
considerable glistening painful tumour appear in one of them 
which no medical treatment could remove. 
Thrush. — There is a disease situated between the lobes of 
the frog, termed, in its mildest form, inflammation of the frog 
( fourchette echauffee ), in its more advanced stage, rotten frog 
{fourchette pourrie ), and which at length degenerates into the 
affection called crapaud . Although this disease has been ne- 
glected by some practitioners, and treated contrary to all common 
sense by others, it has for many years been the subject of our 
study. It commences with considerable pain in the back part 
of the foot — lameness quickly follows, then a purulent discharge 
from and a fungous softening of the two lobes of the frog. 
To remove this disease, which may be followed by a cancerous 
degeneracy of the frog and the loss of the horse, the ulcerated 
and softened portions are cut away, even from the pyramidal body 
itself, and as far as the plantar aponeurosis (the aponeurosis of 
the flexor perforans tendon), if the disease should have pene- 
trated so far. A simple dressing with diluted spirit of wine, and 
pressure carefully made on the part by means of longitudinal 
and cross splents (au moyens d’eclisses et d’une traverse) , will 
usually effect a cure. We have no instance of a return of the 
disease, although we have operated on more than twenty horses. 
Strains of the Scapulo-humeral Joint. — A prac- 
titioner has lately boasted much of the employment of a long
