These figures show that the gilt surroundings have much more powerful effects than 
the white surroundings in producing gilded pupae. 
It will now be of interest to place the percentages of these various colours below

In the above lists the effects of blinding and snipping off the bristles are also 
recapitulated. The transference experiments and the conflicting colour experiments 
have been already systematised as far as it is advantageous to do so ; for the details 
are of paramount importance, being absolutely necessary for the interpretation of the
