RECAPITULATION 49 



are probably subject to many the same contagious 

 diseases; if domesticated these forms would vary, 

 and they might possibly breed together, and fuse 

 into something 1 different (from) their aboriginal 

 forms; might be selected to serve different ends. 



Now the Creationist believes these three Rhi- 

 noceroses were created 2 with their deceptive 

 appearance of true, not (illegible) relationship ; 

 as well can I believe the planets revolve in their 

 present courses not from one law of gravity but 

 from distinct volition of Creator. 



If real species, sterile one with another, differ- 

 ently adapted, now inhabiting different countries, 

 with different structures and instincts, are ad- 

 mitted to have common descent, we can only 

 legitimately stop where our facts stop. Look how 

 far in some case a chain of species will lead us. 

 (This probably refers to the Crustacea, where the 

 two ends of the series have " hardly a character in 

 common." Origin, Ed. i. p. 419.) May we not jump 

 (considering how much extermination, and how im- 

 perfect geological records) from one sub-genus to 

 another sub-genus. Can genera restrain us ; many 

 of the same arguments, which made us give up 

 species, inexorably demand genera and families and 

 orders to fall, and classes tottering. We ought to 

 stop only when clear unity of type, independent of 

 use and adaptation, ceases. 



Be it remembered no naturalist pretends to give 

 test from external characters of species; in many 

 genera the distinction is quite arbitrary 3 . But 

 there remains one other way of comparing species 



1 Between the lines occurs : " one (?) form be lost." 



2 The original sentence is here broken up by the insertion of: "out of 

 the dust of Java, Sumatra, these (?) allied to past and present age and 

 (illegible), with the stamp of inutility in some of their organs and conversion 

 in others." 



3 Between the lines occur the words : " Species vary according to same 

 general laws as varieties ; they cross according to same laws."
