I believe that the eye of every living creature was produced by 

 natural selection, although in some species it consists of 4,000 lenses, 

 in others 12,000, 17,000, or 25,000, and in others of various other vast 

 numbers. 



I believe that my theory is right, although I allow that according 

 to it " all nature" ought to be " in confusion" instead of the species 

 being, as we see them, " well denned." (Darwin.} 



I believe " there seems to me no great difficulty in believing" 

 (Ddrichi) that the swim-bladder in fishes "though originally constructed 

 for one purpose," has been " actually converted" " into a lung or organ 

 used exclusively for respiration." 



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

 by " natural selection," although it is " impossible to conceive 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 cases of luminous insects. 



I believe that the most simple parts of species are due to natural 

 selection, although I see that their "importance does not seem suffi- 

 cient to cause the preservation of successively varying individuals. 1 ' 



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

 "fly-flapper" (!), although I cannot explain how the species did with- 

 out it in previous countless ages before it grew to its present length, 

 when, no doubt, there were just as many flies in those hot countries, if 

 not more, than there are now. 



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. 



I believe that long tails are necessary to animals in hot countries 

 to give them the " power of resisting the attacks of insects," although 

 I see that sheep have heavy tails which they cannot and do not 

 make use of for any such purpose, and are especially attacked by flies on 

 their heads, which, if their tails were ever so light they could not 

 possibly reach. 



I believe that as I hold that the swim-bladder in creatures of the 

 sea is modified into lungs in their descendants changed into land 

 animals -the tail, having been so useful to the former as a means of 

 locomotion, still proves its origin in the latter, though of so little use 

 to them. 



I believe that the green colour of the green woodpecker is due to 

 selection by the male or female bird, because I see that there are black 

 and pied woodpeckers also. 



I believe that it is not the case that many structures have been 

 created for beauty in the eyes of man. or for mere variety, although I 

 ' fully admit that many structures are of no direct use to their 

 possessors." 



I believe that there is "110 logical impossibility in the acquire- 

 ment of any conceivable degree of perfection through natural selec- 

 tion," although I must admit that the case of the eye is "more than 

 enough to stagger any man." 



I believe that the Imerican ostrich "is not yet perfect," although 

 I can give no proof whatever that it is in the process of becoming 

 so. 



I believe that the " most wonderful of all known instincts," that 

 of the hive bee, can be explained by rne, as a Darwinite, and the
