It will be seen in this table that three of these five lobsters were 

 very young and that the other two were more mature, hut in no in- 

 stance had the regenerating limbs attained the normcd size cU the first 

 moult. Moreover, in the case of the last lobster. No. 108, it may be 

 observed that both members of the second pair of legs were regener- 

 ating at the same time. But even then, at the next moult, the new 

 pair of legs were not the same size when compared with each other 

 and differed by as much as fifteen mms. in length. 



These data are characteristic of a large number of similar obser- 

 vations, so the conclusion seems evident that the walking legs do not 

 always attain the normal length at the first moult; it also follows, 

 therefore, that the interpretation that the walking legs regenerate 

 to a normal size at the first ecdysis for functional or other purposes 

 is not necessarily true. 



A word might be added with reference to Brooks's observations. 

 It is quite probable that his results may be explained in another way. 

 It should be observed that my experiments were made during the 

 summer months. Now, if a limb were removed during the winter, 

 in which case the next moult would not occur for a comparatively 

 long time, it is possible that under such conditions the given limb
