CHAP. IT. JUMPING OP CATERPILLARS. 117 



partially scattered among other animals. Cuvier has 

 truly remarked*, that they exhibit those of every other 

 species of animal, such as walking, running, and jump- 

 ing, with quadrupeds ; flying with birds ; gliding with 

 the serpents ; and swimming with the fish. Hence, it 

 is not poetical to assert that " the universal movement 

 of these restless little creatures " gives " life to every por- 

 tion of our globe, rendering even the unfrequented desert 

 interesting." f This feeling was felt by the venerable 

 Derham, when he expatiates on "the admirable me- 

 chanism in those that creep ; the curious oars in those 

 amphibious insects that swim and walk; the incom- 

 parable provision made in the feet of such as walk or 

 hang upon smooth surfaces; the great strength and 

 spring in the legs of such as leap ; the strong-made 

 feet and talons of such as dig ; and, to name no more, 

 the admirable faculty of such as cannot fly, to convey 

 themselves with speed and safety, by the help of their 

 webs, or some other artifice, to make their bodies lighter 

 than the air,":f: To attempt a description of all the 

 different motions discernible in this innumerable class 

 of animals, would here be impossible ; for it would be 

 interminable. " How wonderful are thy works, O Lord! 

 The earth is full of thy riches ! " When, on a bright 

 summer's day, we look around and see the air, the earth, 

 the waters, nay, every pendant leaf and blooming 

 flower, instinct with life, and teeming with creatures, 

 each of whom has habits and movements peculiar to 

 itself, how should our minds be struck with astonish- 

 ment, and warmed with gratitude to that overruling 

 Power, in whose sight this globe is but a grain of sand, 

 yet whose watchful care is over the least of his crea- 

 tures ! 



(138.) Different motions belong to each of those 

 states through which most insects pass before they reach 

 maturity. In the larva or caterpillar form, none 

 are more curious than the jumping, although footless,
