%* ' There is a struggle for existence leading to the preservation of 

 each profitable deviation of structure or instinct.' 



' If one species has any advantage over another it will, in a very lirief 

 time, wholly or in part supplant it.' 



'The very process of Natural Selection constantly tends, as ha< been 

 often remarked, to exterminate the parent forms and the intermediate ,iuks.' 



' All the intermediate forms between the earlier and later slates, us well 

 at the original parent species itself, will generally tend to become extinct." 



' The whole history of the world as at present known, although of a 

 length quite incomprehensible by us, will hereafter be recognised as a mere 

 fragment of time, compared with the ages which have elapsed since the 

 first creature, the progenitor of innumerable extinct and living descendants 

 was created.' 



Innumerable species, genera, and families of organic beings have all 

 been descended, each within its own class or group, from COMMON PARENTS.' 



' I believe that animals have descended from at most only four or five 

 progenitors.' 



' Analogy would lead me one step further, namely, to the belief that all 

 animals and plants have descended from some ONE prototype.' 



4 1 should infer from analogy that probably all the organised beings 

 which have ever lived on this earth, have descended from some ONE 

 primordial form. 1

" I venture to think that no system of Philosophy that has ever been 



taught on earth lies under such a weight of antecedent improbability." 



THE DUKE OF ARGYLL, in the Contcnqwrary Jtevicw. 



" With minds off their balance, inconclusive arguments, confidently pre- 

 sented and reiterated, very easily pass for proofs. The history of human 

 thought is full of baseless speculations, which nevertheless in their day 

 attracted crowds of enthusiastic disciples." 



LORD SELBORNE, LORD CHANCELLOR OF ENGLAND. 



" Dogma often rages where we least expect it. Among scientific men 

 the theory of evolution is at present becoming, or has become, a dogma. 

 What is the result ? No objections are listened to, no difficulties recognised, 

 and a man like Virchow, who has the moral courage to say that the descent 

 of man from any ape whatsoever is, as yet, before the tribunal of scientific 

 zoology, 'not proven,' is howled down." Professor MAX MULLER, in the 

 ftorary Itcriac. 



" While facts should be taught, conjecture should only be mentioned as 

 conjecture. The production of the first organism out of inorganic 

 matter has never been proved, and the connection between monkeys and 

 men is unintelligible to those who are content t :<>m what comes 



under their observation. Every attempt to form our problems into 

 doctrines, to introduce our hypotheses as the bases of instruction by a 

 religion of evolution be assured, gentlemen, every such attempt will make 

 shipwreck, and in its wreck will also bring with it the greatest perils for 

 the whole position of science.
