Abstract
THE published records respecting the use of dredges for natural history purposes carry us back to scarcely more than a century and a quarter ago, when Otho Frederick Müller, a prominent Danish naturalist, began his studies of the aquatic life inhabiting the coasts of Norway and Denmark below the shore-level. The dredge he used, a very simple affair, was, so far as we know, the first one ever devised for the special needs of the naturalist ; and yet, with only a single important modification as to the shape of the frame, it has been handed down to our time as the most efficient appliance for the ordinary purposes of dredging.
