Magnetic Disturbances in Russia.

The Russian province of Kursk proves to be one of the most remarkable areas of magnetic disturbances yet known. Mr. Moureaux reports that the differences between theory and observation are so great that it is not possible to draw isomagnetlc lines, and the magnetic force is as great as it would be in the immediate vicinity of the magnetic poles. The dip of the needle ranges from 48 to 79 degrees. At two points, about 450 yards apart, the declinations are minus eleven degrees and plus forty-five degrees, and the variation at two places about a mile and a quarter apart is from minus thirty-four degrees to plus ninety-six degrees. Nothing near the surface to cause these anomalies is known to exist.
