on to the ground surface of the toe of the shoe. The ol ject ir 
applying this contrivance was to prevent flexion, to keep ‘he di- 
vided ends of the tendon apart, and to guard against direct uniop 
of the same. The operation finally proved successful,

ae given in the “ Veterinary Record:” 
“ This most extraordinary case was observed in September, 1856, 
three months after the inundation of the Rhone, on a farm near 
this river. ‘The subject of the disease was a filly, three months 
old. She was born perfectly straight on her legs, but about fifteen 
days after birth the fore-limbs became bent, and the deformity 
increased so rapidly that when Brachet saw the animal it moved 
onits knees. It was with great difficulty that, by efforts to extend 
the limb, the acute angle formed at the knee could at all be 
widened, and such an experiment gave great pain to the animal. 
The dam being taken out of the stable, Brachet was astonished 
to see the filly walking after her on her knees, almost as fast as if 
progressing naturally. On the front of the knee the skin was hard 
and callous, the tendons behind it were rigid and immovable, and 
Brachet decided on performing tenotomy. The animal was cast 
and the near fore-leg operated upon. An incision was made, about 
an inch in length, at the back of the arm, in a line with the upper 
part of the carpus; the tendon of the flexor metavarpi externus 
was first cut, then one of the medius, and, lastly, that of the inter- 
nal flexor of the metacarpus, when the limb straightened. A 
splint was placed in front of the leg. Eight days afterward the 
off limb was operated upon; fifteen days later the splints were 
removed, and, in the course of a month, the filly stood well, but in 
moving carried her fore-legs forward in a piece. Flexion at the 
knee could not be effected, but the young animal improved rapidly ; 
the limbs became strong, and though slightly bowed, their action 
was perfect. Brachet believes the deformity arose from rheuma- 
tism, induced by the damp on the occasion of the overflowing of 
the river near the farm.” 
The following is Mr. PERCIVALL’s method of performing te- 
notomy foi sprung knees: 
“The operation of tenotomy, though a formidable one for the 
patient, is not a difficult one for the operator. The object is sec- 
tion of the flexor tendons, the effect of which, as we have seen, is ‘e
