reproduction of the Legs in Crabs and Spiders. 291 



in the following experiments, "mutilated," Avithout noticing the mode* 

 or situation, (at least half were at the suture,) and here, as well as previ- 

 ously, I have paid no attention to the regular sequence of dates. They 

 happen, from the mode in which the notes were registered at the time, to 

 be mixed ; and as the only thing of consequence is, that each experi- 

 ment should be consistent in its own individual dates, I have not taken 

 the trouble of further arrangement.
