Abstract
THESE charts are issued in the form of an atlas, and deal in a very complete manner with the barometer means and range of all oceans. The months for which separate charts are given are February, May, August, and November, which have been selected to represent the mean values for winter, spring, summer, and autumn respectively in either hemisphere. In addition to the large charts, which give the material in considerable detail, there are four index charts, on a smaller scale, which exhibit for the same months the isobars, or lines of equal pressure, over the entire globe. These are followed by four charts, on the same scale, showing the range of barometrical pressure. The observations have been derived from logs and documents deposited in the Meteorological Office; logs and remark-books of Her Majesty's ships, furnished by the Admiralty; published narratives of various voyages, and various published results of other nations; also observations at coast stations and islands obtained from all available sources. The number of observations obtained from the Meteorological Office logs for the several oceans are: the Atlantic Ocean, 339,300; the Indian Ocean, 162,000; the Pacific, 88,300.
