The Pasteur monument was dedicated at Lille, France, the city in which the subject of the memorial performed his earlier more important researches, April 9th. The ceremony was witnessed by a large assembly, which included many eminent scientific men of France and foreign countries, among whom men engaged in similar researches to Pasteur's were especially represented. The monument, the fruit of a public subscription, represents Pasteur standing on the summit of a column of Soignies stone, holding in his right hand an experimental flask. At the foot of the column a woman presents her child, which has been bitten by a mad dog, for treatment. To the left is a group representing inoculation--a woman, personifying science, injecting serum into a child she holds on her knees. Three bas-reliefs represent respectively Dr. Roux inoculating a sheep for anthrax, Pasteur studying fermentation, and the first antirabic inoculation of the young Joseph Meister, who is held by his mother, wearing the broad-flapped Alsatian bonnet. The statue is in light bronze, and with the gilded bas-reliefs harmonizes well with the gray of the stone. Addresses were made by M. Armand Gautier and M. Duclaux, who said that the improved laboratories now enjoyed by scientific institutions in Paris were largely due to Pasteur's efforts. The minor planet recently discovered by Witt, remarkable as having an orbit that comes within that of Mars, and provisionally known as DQ, has been named Eros. An examination by Professor Pickering and Mrs. Fleming of the Harvard photographs has revealed traces of this body on twelve plates taken in 1893 and 1894, and on four plates of 1896. By the aid of these plates it has been possible to determine its elements with greater accuracy than would otherwise be possible. Its mean distance from the sun is 1.45810, its shortest distance 1.13334, and its greatest distance 1.78286 that of the earth; the eccentricity of its orbit is 0.222729, and its period is 643.10 days. Its synodical period is such that it has three oppositions in seven years. The next opposition will be in the last months of 1900, and will be a moderately favorable one for observation.
