Method of stabbing Hoven Cattle. AS 
pitch spread on brown paper,* about the size of a crown 
piece. All the danger incidental to the common mode 
of stabbing with the knife is effectually prevented by 
the canula being left in the incision when the trocar is 
withdrawn. | 
‘he small expense of the instrument, its portability, 
the ease with which it can be used by an individual, its 
safety and efficacy in use, as it has not in any instance fail- 
ed of complete success, will, I hope, be sufficiently evi- 
dent to recommend it to the attention of the society. A 
great saving would arise to the owners of cattle, and to 
the country at large, from a general adoption of its use. 
A feeding ox will thrive as well after the operation | 
as if it had never been affected by the disorder. Cows 
in calf are in no danger from its use. It has been found 
particularly beneficial in preserving rearing calves and 
young cattle, when afflicted with this disorder, which 
~ had heretofore been fatal to great numbers of them. 
I beg leave to add certificates of a few of those gen- 
tlemen who have witnessed the utility of this method, 
and whose recommendations have stimulated me to 
submit it to the society, in hopes that by their liberal 
patronage it may be rendered more soot beneficial 
to the public. — 
I have the honor, &c.
