 vicinity of my usual country abode. 



Two being taken on the twenty-fourth 

 of September, were carefully preserved in a 

 glass vessel, and for some time regularly 

 supplied with water from the place whence 

 they had been removed. Both were of a 

 beautiful uniform grass green colour, at- 

 tended by a pellucidity at the extremities 

 denoting the investing integument. In 

 six days, the interior began to darken ; and 

 in seven more, four dusky ovuli were per- 

 ceptible within the larger of the planariae, 

 for the two animals were of unequal size. 

 On the eleventh of October, they had in- 

 creased to the number of six, and some 

 were also at that time visible in the 

 smaller animal. They were differently 

 disposed, however, in their respective ova- 

 ries ; all belonging to the latter being ran- 

 ged on one side of the lower extremity, 

 while those of the former were distributed 

 in both.
