[Laughter.] Dr. Cooke said that when he heard of this subject being brought before the Club it struck him as an excellent opportunity to nudge the elbows of the Conservators, and tell them a little of what they as naturalists thought about the conditions under which the protection of public property was being pursued, not only in Epping Forest, but in other places, to the great detriment of those individuals who went puddling in dirty pools to find something to study under the microscope. It was a complaint which had been urged in every instance in which any amount of land had been conserved for the use of the public. In every instance it had been to a large extent destroyed for naturalists, especially those who devoted themselves to the study of minute life. The reason of this might perhaps be traced to ignorance on the part of those who had the control of these works rather than to any wish to injure the wild animals of minute dimensions. They did not measure by inches and feet the animals whose cause they had to advocate. [Hear, hear.] He was not about to propose that they should go to Parliament for a Bill for the Preservation of Bugs and Beetles. [Laughter.] But he did propose that they should try to prevail upon gentlemen who were placed in the position of Mr. Johnston —he was sorry that he should have been compelled to leave before he could whisper a word in his ear—he thought they should try to give them some little information about the work that was being done. To come down to detail. The organisms that he specially advocated were those which were as small, or smaller than a pin's head. These were the organisms that were most injured by the usual plans for the preservation of land for public purposes. They were also the class of organisms which were now exciting the greatest amount of interest among naturalists, who were seeking to solve the problem of life very much through the study of the life-history of the lower and more minute forms. And hence every minute organism which was found in a puddle might teach a great lesson [hear, hear], and a lesson which we could not learn by staring at a lion or rhinoceros. There were in London, as well as in Essex, a large number of people associated together in societies for the study of forms of microscopical life. He had the honour to be the president of one society of 200 members, and the vice-president of another which contained over 600 members ; and the general feeling amongst those, nearly a thousand individuals, was that every year they had to go further from London in search of the organisms they studied. The excursion parties of the Quekett Club had found it no longer of any use to go to Wimbledon Common in quest of minute life—the place had been given over to the tender mercies of the volunteer and drain-maker. Hampstead Heath was another instance—and a very good instance—of a heath which had been preserved for the benefit of the Cockney ; but it had been now nearly destroyed for the purposes for which the London naturalist particularly desired it to be preserved, Then Battersea was a third
