OF THE PROFESSION.

A complete revolution has been formed in the opinion of vete¬ 
rinarians respecting cataract, by the communications of Messrs. 
Cartwright, Clay, Hale, Harris, Percivall, Spooner, and others. 
It may be produced without apparent previous inflammation—it 
may come almost of a sudden—it may not necessarily impair 
vision—it may, and does frequently, disappear; and we are 
beginning to have a conception—perhaps, as yet not a very cer¬ 
tain one—of the circumstances which may guide our prognosis 
as to its serious character, and its probable duration. 
Some experiments, almost invaluable, by M. Leblanc, respect¬ 
ing the effects of wounds penetrating into the chest, have been 
laid before the British public. 
That which will hereafter be considered as one of the noblest 
improvements in our practice, the use of the chloride of lime in 
many cases of grease, and in all fistulous wounds, has found 
powerful advocates in Mr. Simpson and Mr. Holford. 
Chrochles in cattle.’^—We are indebted to Mr. Tate for the 
first intelligible account of this singular disease. Mr. Cooper 
and Mr. Corbet on the chords in cattle must not be forgotten ; 
nor the explication of grass-ill by the latter. 
The division of the flexor tendons has been considered by 
various contributors ; Mr. Young’s cases of successful division 
of them are gratifying ; the explication by Mr. Dick is luminous 
and conclusive: and there is no doubt that if the operation is 
undertaken with proper selection and precaution, and the horse 
is not set to work too soon, or cruelly abused, it will be generally 
successful. The accounts of the rupture of the perforatus and 
perforans, by M. Pattre, do him much credit: and Mr. W. C. 
Spooner’s case of division of the flexor tendons of both legs is 
a most valuable addition to our surgical practice, and reflects on 
him much credit. 
Mr. Friend, and Mr. Harrison, have illustrated the mechanism 
and functions of the stomachs of ruminants. It is an important 
subject, and the want of definite knowledge with regard to it 
is often the source of sad annoyance to the practitioner on 
cattle. 
Mr. Friend’s frog-pressure shoe has peculiar value in all cases 
of sunk soles, and when it is desirable to relieve the lamina) as 
much as possible. The shoe is both sim])lc and ingenious, and
