the tepid alkaline baths mentioned by Hertwig. At times, at in¬ 
tervals of about eight days, and then during two consecutive days, 
a good friction with blister ointment above the coronet is advan¬ 
tageous, as well as one with Lebas’ ointment. English practitioners 
prefer salines; the better treatment would be to turn the animal 
to grass. Brauell advises iodine internally, and says he has found 
it work well. Others recommend diuretics. Setons in the shoul¬ 
ders or chest, seem to us inexpedient. We prefer the administra¬ 
tion of a purgative ball every eight days. Sewell and Brauell advise 
a seton, running from the hollow of the coronet through the 
plantar cushion, a little behind the tendon of the perforans, and 
within a short distance, therefore, of the diseased capsule, making 
its exit at the anterior third of the frog. This drain is to be main¬ 
tained for two, three, and even four weeks; Sewell,Brauell, Hert¬ 
wig, and several other veterinarians, English especially, claiming 
much benefit from it. This seton is introduced by means of a 
curved frog seton-needle; it has been used but little in France. 
Bruner has recently proposed the puncture of the sesamoideal 
capsule with a trochar, introduced in the hollow of the coronet, an 
operation only practicable if the serous collection can be felt out¬ 
wards. After the puncture he recommends an injection of iodine. 
Lafosse proposes after the removal of the sole, the transversal 
incision of the plantar cushion, with removal of a part of it, 
down to the tendon, following the axis of the sesamoid ; then the 
cauterization of the bone and its cartilage, in imitation of what is 
sometimes done in punctured wounds of the foot. Brauell rec¬ 
ommended as a Useful surgical operation, the section of the perfor¬ 
ans tendon in the metacarpal region, in order to prevent friction 
against the sesamoid groove, and to allow an easier adhesion be-

tween the tendon and the bone. But it is to be feared that this 
section, supposing that it proves successful, might so weaken the 
tendon as to render the animal unfit for fast work. 
' Tf navicular disease should be accompanied with deviation of 
the wall* and contraction, true or false, the treatment will be that 
of this affection iU its simple form. An operation, often recom- 
riiended, has been that of neurotomy, upon the posterior branches 
of the plantar nerves, repeated at intervals of at least fifteen
