And so on vvith otter creatures which happen to ingest the ova of different and appropriate parasites. To hares and rabbits the dog thus communicates another bladder-worm disease ; and we ourselves are also liable to become infested with hydatids from the same source. Another parasite of this class is described as follows by Dr. Cobbold : " The largest tapeworm liable to reside in the dog is a parasite chiefly derived from the sheep ; that is to say, the sheep acts as the principal intermediary bearer of the larval cestode, which latter acquires tapeworm maturity when it is taken into the stomach and intestines of the dog along with ilesh food. The entozoon in question is the margined tapeworm. This worm {Tcenia marginatd) reaches a length of from five to eight feet. It is an abun- dant species, occurring, probably, in fully 25 per cent, of English dogs that are not less than one year old. In.
