Waskom.—Bulls run daily with cows and are doing service. 
College Station.—All the heifers appear to be pregnant. 
Kruger.—The oldest heifer produced a good calf 9 months 
after inoculation. 
We have but little data as to the dangers of abortion follow¬ 
ing inoculation. Only one case has occurred in our experi¬ 
ments. This one in a Hereford heifer recently inoculated at the 
Missouri Experiment Station. On this point Dr. J. S. Hunt 
(Pathologist to the Department of Agriculture, Queensland, in 
Annual Report for 1897-98, page 87), says: “The risk is 
greater in cows that are in calf ; abortion frequently follows 
inoculation when considerable fever occurs.” 
DOUBLE NEURECTOMY FOR SPAVIN. 
By Adolph Eichhorn, D. V. S., House Surgeon, American Veteri¬ 
nary Hospital, New York. 
There is hardly a veterinarian who has not met cases of 
lameness caused by bony spavins, which resisted the most 
heroic treatment, beginning with a liniment, followed by blis¬ 
tering, firing and blistering, or even the perforating iron, and 
being in every way unsatisfactory to both owner and veteri¬ 
narian. For the last few months foreign veterinary literature 
has contained many articles, reports and results of an operation 
called the “ Double Neurectomy for Spavin,” and in which I 
took a great deal of interest. Speaking about it to several veteri¬ 
narians, I have been requested to describe this operation, which 
was introduced by Prof. Bosi, of the Bologna Veterinary School, 
and whose successes surprised the profession. 
The operation of neurectomy in veterinary surgery is by 
far of much greater importance than in human surgery, for in 
the latter this operation is only in very rare instances indicated, 
as in cases of neuralgia. But in the horse the indications are 
much more numerous ; taking in consideration the chronic in¬ 
curable diseased conditions of the bones, ligaments, tendons and 
joints of the lower extremities, which, by producing continual 
pain, interfere with the usefulness of the animal.
