EXTRACTS FROM EXCHANGES. 
is now no longer the property of the old-fashioned gelder; it 
has entered in the domain of veterinary surgery, where it always 
belonged, and now the operation thoroughly taught in vet¬ 
erinary schools is performed by veterinarians with as much will¬ 
ingness as in days gone by it was declined as too dangerous 
to'the patient, too difficult for the surgeon and too risky for the 
interests of the owner. Yet the operation has received many 
modifications since the first days of its introduction in the 
schools. Prof, kabat, of Toulouse, has also published in the 
Revue Veterinawe the results of a long series of operations 
which he has performed, and which, with one exception only, 
proved successful in all the others. The 53 cases upon which 
he operated were as follows: ist. Eight cases of double abdom¬ 
inal cryptorchidy, 8 recoveries. 2d. Thirty-seven cases of unilat¬ 
eral abdominal cryptorchidy, 36 recoveries and one death. In 
this case the operation was complicated by an eventuation, with 
peritonitis, that killed the horse in three days. 3d. Eight cases 
of inguinal cryptorchidy, with 8 recoveries. The results of the 
operations as far as the character and disposition of the patients 
were all most satisfactory. 
Plantar Neurotomy. —How much has been said against 
the propriety of the operation of plantar neurqtomy, and how 
near has the discovery of Sewell been of being pushed entirely 
aside from the therapeutics of some peculiar forms of lameness. 
In onr days, on the contrary, specially on the Continent, it has 
been more thoroughly studied, its indications, its applications, 
its sequelae, are familiar to all. And yet there are still some 
practitioners who hesitate. In the Journal of Zootechnie^ Prof. 
Cadeac brings another word of encouragement to the hesitating 
surgeons. After considering and criticising the objections and 
the complications, after showing the proper way of nenrotom- 
izing, viz.: a free incision, the removal of a piece of nerve, not 
less than five inches^ and a cicatrization by first intention, through 
proper antiseptic measures. He concludes his remarks by say¬ 
ing : Nenrotomize always for navicular disease, never for 
chronic laminitis. 
Foreign Body in the Pharynx of a Cow. —Mr. Mathes 
reports in the Journal of Zooteclinie a very interesting case of 
this class of lesion, in which a cow presented all the indications 
of a severe traumatism of the left guttural region, characteripd 
by swelling, phlegmonous inflammation, difficulty of mastica¬ 
tion, abundant salivation, etc. A first examination of the fauces 
with the mouth kept open by speculum, revealed nothing at
