The Eiffel Tower.
The daily movement of the Eiffel Tower, due to expansion and contraction, has been studied by Colonel Basaot, who recently explained to the Academy of Sciences that the expansion of the metallic components of tho structure produces a torsion movement from sunrise to sunset which traverses a curve of ten centimeters. This movement is repeated in an inverse direction during the night, as the column becomes cooled, so that the lightning rod on the summit of the tower is in constant motion. In summer tho expansion is superior to that in winter, and the movement reverses at night, owing to contraction due to the cooling 1 down of the mass. Yet this twisting, this torsion, iv no case compromise the solidity of the .structure,, which jls absolute, '
