dependence upon each other, must be studied. 

 Going lower still, the conditions that suit these 

 conditions, even to their chemical and microsco- 

 pical analysis, peep out, and a grand scheme of 

 a new science, a new phase of creation, is, as I 

 have said, dimly foreshadowed, in which the 

 food of man is the dependent consideration. 



Were we to study to understand the position 

 in creation which every insect fills, the great 

 secret would not be to us the jumble which it is, 

 and we should begin to appreciate the beauty 

 and harmony of the works of the Creator, and 

 to see the wickedness and absurdity of interfering 

 to disarrange them. The aquarium has hitherto 

 been an interesting scientific trifle ; henceforth 

 it should be a link in this great chain of obser- 

 vation. It will be seen, by the few remarks I 

 have made, that this science requires to be, and 

 is capable of being, widely popularized. I shall 

 touch further on these matters in the body of 

 my work as I find occasion. 



It may be urged that, in the succeeding pages, 

 I have taken somewhat too wide a range of sub- 

 jects into the study of Pisciculture. I do not
