PLAIN TEACHING. 



the shell only covers the front 

 half of the body ; the other organs 

 are gradually developed during 

 successive moultings. 



The cyclops, 19, is so-called 

 from possessing one eye only.

These little creatures, which 

 abound in standing waters, are 

 seldom more than one-eighth of 

 an inch long, and may be observed 

 frequently jerking about by the 

 aid of their long tails. In their 

 forms they somewhat resemble a 

 lobster. The abdomen is forked 

 at the extremity, and the eggs 

 are carried by the female in two 

 large sacs attached to the byfid 

 tail. The eggs, which are of a 

 brown, blue, or green colour, 

 varying according to their age, 

 become transparent when nearly 

 ready to produce the young. A 



female cyclops m the space of 

 three months gives birth to not 

 less than ten distinct broods. 

 There are marine, as well as 

 fresh water species. 



The interest attaching to the 

 study of the habits of various 

 animals has led to the intro- 

 duction of the aquarium, in 

 which collections of fresh and 

 ocean water animals and plants 

 may be kept and observed. 



" I know of nothing " (3ays Mr. Noel Hum- 

 phreys) " more likely to stimulate the mind to 

 healthy exertion, and take it out of the imme- 

 diate track of common interests and pleasures, 

 the monotony of which is so oppressive, than 

 the study of natural v^tory in some of its 

 least explored fields, especially its extraordinary 

 [development in conne^nn with the waters of 

 [the river* and ocean... And yet, how few there 

 [are who seek that charming mode of dissi- 

 pating the dreary monotony of social life, such 

 as it is made by the routine of fashion and 

 habit >" 



A love of Nature is, to our 

 minds, one of the strongest indi- 

 cations of a love cf God: — 



" See through this al:* ( this ocean, and this 



earth, 



All matter quick, and bursting into birth. 

 Above, how high progressive life may go! 

 Around, how wide! how deep extend below! 

 Vast chain of Being ! which from God began, 

 Nature's ethereal, Inman, angel, man; 

 Beast, bird, fish, insect, what no eye can see, 

 No glance can reach ; from infinite to thee 

 From thee to nothing ! On superior powers 

 Were we to press, initrior might on ours , 

 Or in the full creation leave a void, 

 Where, one step broken, the great scale's 

 destroyed ; 



From Nature's chain whatever link you 

 strike, 



Tenth, or ten thous<u.:!th, breaks the chain 



alike. * 



All are but parts r* one stupendous whole, 

 Whose body Nature is, and God the soul J"
