Cooke It seems hard to realise that there is a world of animal and vegetable life, which is scarcely dis- cernible by the naked eye, and was quite unknown, except in a few particulars, to our ancestors of one hundred years ago. And yet the perfection of the microscope, and the accession of such a crowd of manipulators, has rendered the study of pond life, as well as that of other minute organisms, one of the features of the age. In works which treat of the natural history of any district it is no longer permissible to ignore the " infinitely little," and leave the noble army of field workers with the microscope out of consideration. It is undoubtedly true that there are a large number of earnest amateurs in science, who trouble little about our Forest quadrupeds or birds, except for their hairs or feathers, and the parasites which flourish amongst them ; or for our trees and wild flowers, except for the spots and distortions of their leaves, and the objects which cause them. The lover of nature is no less interested in the hidden mysteries of the ponds, pools, and swamps of the Forest, than in its beech and hornbeam, and is as anxious for the preservation of objects almost invisible, as of the monarchs of the Forest and the beauties of the glade. For such as these there are ample fields of research, without in the least de- tracting from the general utility of the Forest to those who care for none of these things. The water area of the Forest is considerable, in addition
