 from being perplexed by them, will assuredly, amidst 

 all their varieties of form, very soon detect the true

 that no species whatever exists in nature, but that every, 

 even the remotest form, may be evolved from the other 

 by intermediate links, — till then we must be allowed to 

 rely upon the course already indicated. Let the master
