DISEASES OF SHEEP. 



-»♦*- 



The followino^ 

 is an Essay, for 

 which the United 

 States Agricultural 

 Society awarded 

 their medal and di- 

 ploma, in the year 

 1861, to Robert 

 McClure, of Phila- 

 delphia^ Pa. 



The diseases of sheep which are laid under contribution 

 are : — First Those that are the most frequent and destruc- 

 tive, therefore of the greatest interest and concern to the 

 sheep farmer. Second. Those in which treatment and 

 ^preventative means can be employed with profit and suc- 

 cess. Third. Those the pathology of which has been in a 

 measure or entirely misunderstood, therefore wrongly 

 treated, and the preventative measures neglected or mis- 

 applied. 



These diseases will embrace a large number of maladies 

 that have been treated of separately in the work by the 

 late Wm. Youatt as independent affections, when literally 

 a great many diseases alluded to by this indefatigable 

 writer are but different degrees and conditions of the same 



morbid phenomena.
