Method of stabbing Haven Cattle. AS 



pitch spread on brown paper,* about the size of a crown 

 piece. All the clanger 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 withdrawn. 



The 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 generally beneficial 

 to the public. 



I have the honor, &:c.
