intestines of dogs or cats,

found a representation of 

 the Teenia Echinococcus, a very frequent 

 and dangerous guest of the interior parts of 

 the dog. 



In Fig. 1419 is shown the scolex, or head, 

 of this formidable-looking creature .detached from its membrane, 

 and in Fig. 1420 the same, greatly enlarged, adhering to the mem- 

 brane to which it is attached when generated.

 senting, as respect-
