PLANARIA FELINA. G3 



others, was of small size ; its tail was bifid, 

 and out of the cleft grew a body, quite se- 

 parate and distinct from the main trunk of 

 the animal, and preserving an erect pos- 

 ture, while the two tails were applied to the 

 plane of position below. In reasoning from 

 simple appearances, two conclusions might 

 be deduced : first, that the posterior extre- 

 mity of this planaria had been accidentally 

 cleft into three parts, but all having sepa- 

 rated by spontaneous division, only two 

 were renewed by the ordinary course of re- 

 production ; and the third, situate between 

 them, had, by some strange and anomalous 

 process, been developed into a body, sur- 

 mounted by a head, smaller than the princi- 

 pal body, indeed, but lively ai?d well defined. 

 Secondly, if the parts had not been cleft asun- 

 der by accident, so as to give birth to this 

 inexplicable renewal, the peculiarity could 

 probably be ascribed to an original mon- 

 strous conformation of the germ, or foetus, 

 whether expanding in an egg or in the bo-
