The Illinois Biological Station

In Europe there are twenty-seven or more marine biological stations, one in Japan and five in the United States. The attention of biologists has been given mostly to the study of marine life, but some of the inland scientists are taking to the fresh water, leaving the marine life to be salted down by those near at hand. But it is only of late years that a few zoologists have bethought themselves to halt in their rush to the marine stations and cast a microscopic squint at the myriads of forms dashing and crowding through the water of the lakes and streams, and even inviting the hauls of a net in order to relieve the pressure of an overabundant surplus of population
