sick horses, 3476 entered during the first period, and but 2146 
during the second ; leaving an excess of 1330 for the former. This 
may be owing to the purchases being made principally in winter, 
which causes the number of horses actually in depot to be much 
greater in the first six months of the year. 
Tracheotomy Tube and Trocar, invented by T. W. Gowing, 
M. R. C. V. S . , Camden-town. 
That our science is not stationary, but that as we write the 
spirit of progress and improvement is actively at work among its 
members, no facts more clearly demonstrate than the repeated calls 
made upon us to notice novel inventions connected with the prac- 
tice of veterinary surgery. Numerous, however, as have been the 
recent adaptations and additions made to our means of alleviating 
the sufferings of our patients, we yet think there remains a fair 
field on which ingenuity may be displayed. The pocket-case now 
in use sadly requires that some gentleman, as ready to conceive 
and as able to perfect as Mr. Gowing, should overhaul its contents, 
one-half of which are rarely employed, and the other half of which 
are too small to prove effective upon so large a patient as the horse. 
The French veterinarians long ago felt that the means at com- 
mand were disproportioned to the end desired, and they have 
attempted to remedy the defect ; but, unfortunately, while they 
obtained size, they did not likewise combine it with convenience, 
since a French pocket-case must strongly remind him who beholds 
it of a diminutive portmanteau. Thus, while greater magnitude 
is felt to be desirable, no greater bulk or weight can be tolerated ; 
and how such opposite properties are to be made to harmonize, 
is a problem which those who are endowed with the mechanical 
skill possessed by Mr. Gowing alone can hope'to solve. 
We have, on former occasions, had to speak favourably of 
Mr. Gowing’s talent for invention, and we hear excellent report 
of the practical advantage gained by the teeth-instruments of 
which that gentleman is the author, and which may be found 
figured and explained in “ Mayhew on the Horse’s Mouth.” The
