6 All tlie Articles of the Darwin Faith. 



I believe that the " electric organs of fishes " have been 

 produced by " natural selection," although it is " impossible 

 to coi-.ceive by what steps those wondrous organs have been 

 produced." I believe this, although these organs only 

 occur in species " widely remote in their affinities," while 

 we " might have expected " (on Darwinian grounds), that 

 they would all ' have been specifically related to each other. 

 I believe the same in the like case of luminous insects. 



I believe that the most simple parts ol species are due 

 io natural selection, although I see that their " importance 

 does not seem sufficient to cause the preservation of 

 successively varying individuals.'' 



I believe that the tail of the giraffe has grown by degrees 

 into a "fly-flapper" (!), although I cannot explain how 

 the species did without it in previous countless ages before 

 it grew to its present length. 



I believe that every "well-developed tail" in a water 

 animal has been worked in as a "fly-flapper" for land 

 animals, or as a "prehensile instrument," or to "help 

 them in turning ; " although I see that in the dog it is of 

 next to no such use at all, and that the hare " can double 

 quickly enough, though with hardly any tail."
