This manual of veterinary operations by Professor Hering, 
of the Royal Veterinary School of Wurtemberg, is now com- 
plete ; the third and concluding part having just been received 
by us. It is a comprehensive work, admirably illustrated 
with numerous woodcuts of the various instruments used in 
veterinary surgery, and also lithographic plates of the parts to 
be operated upon. It gives a full description of every operation 
the veterinary surgeon can be called on to perform, either to 
relieve the sufferings of his patients or to increase their 
value and usefulness. It likewise gives full directions as to 
the preparing of the different animals previous to the per- 
formance of the operation, the fittest time in the day, and 
the season of the year to undertake great or dangerous ope- 
rations; the best means of securing the patient; the acci- 
dents that are likely to occur in the casting, &c. The value 
of anaesthetic agents is inquired into, and the quantity of 
each given necessary for the production of insensitiveness in 
different animals ; the best manner of administering them, 
the dangers to be guarded against, and the means to be re- 
sorted to, so as to restore the animal should an overdose be 
administered. 
The author adds a list of all the works on the same subject 
that have been published in other countries, and after each 
chapter an account is given of similar operations performed 
by members of the profession in different countries, with 
their success or failure. 
The following translation will perhaps give a better idea of the 
style and value of the work than a more laboured description :
