and Dr. Wilson, who traveled nearly one thousand miles, drawing their sleds, after it had been necessary to kill the dogs owing to lack of food. Lieutenant Shackleton, who became ill, returned on the Morning, and is about to publish an account of the expedition. Another expedition headed by Lieutenants Armitage and Skelton went westward, climbing a glacier 9,000 feet high, the ice extending far inland. Other geographical results of interest were the discovery that Mts. Erebus and Terror are on a small island and that MacMurdo Bay is not a bay but a strait. The remaining scientific work of the expedition has not been reported on very fully. Magnetic work was carried on continuously, some 400 magnetograms having been taken; a seismograph was also working regularly; soundings and deep-sea dredgings were made, and undoubtedly valuable zoological and botanical collections were obtained.
THE SO-CALLED MOSQUITO DESTROYER.
The New York Sun of July 13 printed an article to the effect that the Public Health and Marine-Hospital Service had discovered a parasite which would destroy mosquitoes, and from the account it appears as if the service intended to breed these worms in order to use them as a practical means for combating the mosquito plague. As the proposition is one which will doubtless attract popular attention, it will be well to place the exact facts before our readers.
