 bellies remained unmolested, although they 

 shared a pond in which no other frog or newt 

 could live without being eaten." 



That such advertising of character and qual- 

 ity has proved serviceable to each race practic- 

 ing it is implied in the fact that it is most 

 strongly manifested in those of most decided 

 harmfulness in one way or another. 



Among insects, for example, many are so 

 distasteful to birds that they go about in broad 

 daylight quite fearless of being snatched by the 

 fly-catchers which compel most insects to fly 

 abroad only under cover of night and hide 

 quietly during daylight hours. 



In every case such nasty-tasting insects are 

 now brilliantly colored and are easily recog- 

 nized, which has been gradually brought about 

 through the fact that the brightest the most 

 quickly recognized, the best advertisers sur- 

 vived to perpetuate their kind with an ever-in- 

 creasing tendency toward more perfect protec- 

 tion, while the less well marked suffered acci- 

 dents.
