{continued). 



Experiments. 



A. Weismann, 



using 

 Lacerfa viridis. 



Avoided 

 ridis. 



by L. 



E. B. Poulton, 



using three species 



of Lizards and 



Hi/la. 



Eaten by Tery hun- 

 gry L. miiralis, 

 and, I believe, by 

 L. viridis, and yet 

 evidently disliked 

 by all. 



How far support given to 

 Wallace's suggestion, 

 that brilliant and conspicu- 

 ous liir\£e would be 

 refused by some at least 

 of their enemies. 



Strong support. 



Strong support. 



How far support given to 



Poultons suggestion, 



that a limit to the success of 



this method of defence 



would result from the 



hunger which the success 



itself tends to produce. 



No evidence. 



Strong support. 



Strong support in JennerWeirs 

 observation ; and Butler's 

 shows that the hairs are much 

 disliked. 



No evidence, for the Missel- 

 Thrush appeared to relish the 

 larvae. 



L. inuralis, when 

 hungry, bit the 

 larva, retaining it 

 for a long time, 

 but in the end re- 

 jected it, and much 

 irritated by hairs. 



Strong support, on the whole. 

 It is impossible to decide 

 whether the Sky-Lark was 

 killed by the larvtB. If so, it 

 strongly opposes the theory of 

 any instinctive knowledge. 



It is certainly a support to the 

 suggestion that a Lizard when 

 hungry enough should make 

 such a determined attempt to 

 eat the larva, which it evi- 

 dently disliked. 



Entirely disregard- 

 ed by L. viridis 

 until after another 

 similar but pala- 

 table larva had 

 been introduced ; 

 then tasted, but 

 rejected. 



Seized and relin- 

 quished by hun- 

 gry L. muralis, 

 Probably eaten 

 later ; but insuf- 

 ficient evidence. 



Strong support. 



It is certainly a support to the 

 suggestion that a Lizard when 

 hungry enough should make 

 such a determined attempt to 

 eat the larva. 



Devoured by L. vi- 

 ridis, "but not 

 exactly relished." 



Support. 



Strong support. Eaten, al- 

 though unpleasant in some 

 way.
