8:30 PARASITIC DISEASES. 



the main question. Of the method of prevention, if the Taenia 

 cccnuTus were to be expelled from every dog in the country, and 

 effectually destroyed, the disease " gid," among sheep, would be 

 very rare indeed. 



" In reference to the treatment of the disease we have nothing 

 to urge. Puncture or removal of the cyst in many cases 

 alleviates the distress which the animal suffers, but permanent 

 cure is rare, and, .knowing this, the farmer wisely consigns the 

 animal to the butcher. He should, however, always bargain 

 for the return of the head, which contains the parasite, in order 

 that he may burn, bury, or otherwise destroy it, and thus render 

 thousands of embryos inert." 



The various other diseases caused by taeniae, in different 

 stages of development, and other parasites, almost too numerous 

 to mention, are not intended to be described in the present 

 work ; helminthology being a specialty upon which many works 

 have been written. In connection with this I may refer to one 

 small work, namely. The, Internal Parasites of our Domesticated 

 Animals, by Dr. Cobbold, as being the only book which deals 

 exclusively with the entozoa of interest to the veterinarian. 

 Under the able direction of Dr. Tommasi, an Italian edition 

 of this manual has been published at Florence. 



I may, however, state that I have found areca nut, with 

 the etherial extract of the male shield fern, to be the most 

 certain remedy for the expulsion of tape-worms, a tabular 

 arrangement of which is given on the following page. 



The drawings of the parasites have been mamly taken from 

 Zurn, also from HeUer, Krabbe, Leuckart, Cobbold, Kuchen- 

 meister, and others.
