 must accept the occurrence of such phenomena as 

 established facts — ^just as we are compelled, and are 

 now quite accustomed, unhesitatingly to believe in the 

 reality of other equally inexplicable phenomena. When 

 we are able really to explain the reason of the processes 



fish, and another into an insect, we may then with a 

 little more show of reason think of rejecting other more 

 or less similar facts because they are incomprehensible! 



However

be the views set forth in this 



chapter, it might reasonably be expected that others 



mor 



could be shown that many facts long known— though 

 difficult of explanation — were now more easily to be 

 understood. Let us, therefore, briefly glance at a few 

 of these old difficulties. 



We have already alluded, on more than one occasion, 

 to the general accordance between our views and the
