CHAPTER VIII. 



LIKENESSES IN ANIMALS AND PLANTS. 



&quot; The facts of mimicry and of the various lands of homology as ex 

 hibited in comparative anatomy, teratology and pathology, reveal an 

 internal force and dynamic agency, the soul, in each animal, which 

 forms one indissoluble unity with its material frame.&quot; 



IN considering the form and structure of animals and plants, 

 TWO kinds of amongst the different resemblances presented to our 

 considered, view there are two orders of likeness which it is 

 intended here to notice. 



The first of these orders of resemblance is one which is 

 merely external ; namely, the likenesses borne by different 

 animals to others of more or less different nature, to plants 

 or to inanimate objects, and likenesses borne by plants to 

 others of more or less different nature or to animals. This 

 kind of resemblance is termed MIMICKY. 



The second of the two orders of resemblance extends to 

 internal structure, and relates to likenesses of the kind borne 

 by parts of one animal or plant to parts of other animals or 

 plants, and it also relates to likenesses borne by one part of 

 any animal or plant to other parts of the same individual. 



First as to Mimicry : &quot; Mimicry &quot; is a close and striking, 



yet superficial resemblance borne by some animal 



or plant to some perhaps very different object. A 



familiar example of mimicry is seen in the bee and spider 



orchis, and in clear-winged moths, which may be mistaken 



for bees. One of the most perfect examples of mimicry is 



afforded by an insect (of the grasshopper and cricket order) 



which is called, on account of the appearance it presents, the
