In order to complete my resume of the facts of parasitism 

 shown to occur in the sheep, it is needful to speak of the 

 part played by the nematodes, or round worms ; and 

 chiefly so, since one or two of the numerous species of 

 strongle are productive of severe epidemics amongst ovine 

 bearers. What is commonly called " the lamb disease " 

 is simply the equivalent affection of husk, or hoose, occur- 

 ring in cattle ; and it may also be said that essentially the 

 same verminous luug-disease, though brought about by 

 the injurious action of other forms of the round worm 

 group, carries off various domesticated animals, and even
