Charts IX and X, the anticyclone and cyclone tracks, for the months October 1955 through February 1956, and published in the issues for those months, are incorrectly registered with the blue base map. The error amounts to about 100 of latitude and up to 70 - 80 of longitude in the extreme northwestern and northeastern corners of the map, and up to 350 of longitude in the central areas north of

650N. In the center portions across the United States the error is small.

The tracks for March 1956 in this issue are correct.

New corrected maps will be printed for October through

February and forwarded to all subscribers in the near future.
