n8 Polywog Problems [THIRD WEEK 



from now on it is an easy matter to watch the daily growth. 

 There is no greater miracle in the world than to see one of 

 these aquatic, water-breathing, limbless creatures trans- 

 form before your eyes into a terrestrial, four-legged frog 

 or toad, breathing air like ourselves. The humble polywog 

 in its development is significant of far more marvellous 

 facts than the caterpillar changing into the butterfly, 

 embodying as it does the deepest poetry and romance of 

 evolution. 



Blue dusk, that brings the dewy hours, 

 Brings thee, of graceless form in sooth, 



EDGAR FAWCETT.
