Etheridge was always absorbed in his science, and shunned ordinary social life, so that his real good nature could be appreciated only by a very small circle of intimate friends. His scientific worth, however, was widely acknowledged, and he received the Wollaston Fund from the Geological Society of London in 1877, the Clarke medal from the Royal Society of New South Wales in 1895, and the Mueller medal from the Australasian Association in 1911. His name is also associated with the Etheridge goldfield in North Queensland, a high peak on the Kosciusko tableland, and a glacier in Antarctica.



report of observations of a gigantic dinosaurian reptile in the Congo region of Africa, which was made the subject of sensational articles in December last, proves, as we surmised (, December 18, p. 396), to be without foundation. Mr. Wentworth D. Gray, Acting Representative of the Smithsonian African Expedition in the Katanga, writing from Elisabethville on January 21 to the Times of February 23, says:—"I am authorised to contradict the statement that the members of the Smithsonian African Expedition who proceeded to this territory came here to hunt the Brontosaurus.

The first meeting since 1914 of the International Council for the Exploration of the Sea will be held in London on March 2. Delegates will be present from Belgium, Denmark, France, Finland, Holland, Norway, and Sweden. Russia and Germany are not represented, and France sends delegates for the first time. The German investigations, it is now known, have been resumed, and the steamer Poseidon has been working at sea since last September. The council, it is expected, will consider arrangements for the resumption of the pre-war investigations, and will devote special attention to tracing the effects of the restrictions on fishing during the war period on the abundance of fish in the North Sea. Proposals for the closing of certain North Sea areas against steam-trawling are, it is understood, to be considered. Arrangements are being made by the British Fishery Departments for an early beginning of an extended programme of research. The question of the inclusion of Germany has not yet been considered, but it is believed that there is a growing feeling in this country that she should be invited to participate.
