Fig. 56.—Tænia echinococcus, from the pig.
Leuckart has made some very interesting experiments on the echinococci. In [Fig. 57] is shown a tænia which proceeds from an echinococcus.

There is yet another tape-worm harboured by man, the Tænia lata, better known under the name of Bothriocephalus.
We give in Figs. [58], [59], and [60] representations of this worm in the state of a colony, also the scolex or head separately, and an egg. Its history is very curious, especially with reference to its geographical distribution.
