Abstract
VARIATIONS OF THE MARTIAN CANALS.—During the 1903 opposition of Mars, Mr. Lowell observed changes in the canals which he believes were the results of artificial interference. Among the canals mapped by Schiaparelli in 1877 were three, situated on the eastern edge of the Syrtis Major, which met at a common point, the Lacus Tritonis, and which he named Thoth, Triton and Nepenthes respectively. In 1882 and 1884 Thoth appeared double, but was undoubtedly seen, and in 1884 Nepenthes was also distinctly double.
