Publisher's Synopsis
Excerpt from Discussion of Meteorological Phenomena Observed at the U. S. Naval Observatory, Washington: From June 30, 1842, to January 1, 1867
From the establishment of the Depot of Charts and Instruments, in 1842, to January, 1867, a portion of the working force attached to this institution - now known as the United States Naval Observatory - has been employed 'in making and reducing meteorological observations obtained with the Barometer, the Dry and the Wet bulb Thermometers, the Sun Thermometer, and the Rain-gauge, including for a portion of the time a series of Magnetical observations.
In the volume of Washington Astronomical and Meteorological Observations, for 1861, occurs the following announcement The meteorological observations made between July 1, 1842, and January 1, 1861, will be published in separate volumes as rapidly as they can be prepared for the press - but the pressure of other duties during the late war prevented the prosecution of this scheme, and though a portion of the work was transcribed from the original records, and partially prepared for the press, no investigation of the character of these observations was attempted until 1867.
In this investigation it was proposed, first, to ascertain, if possible, the adopted methods of observation from 1842 to 1861 - second. To learn how far the observations were made m accordance with the adopted plan, and third, to deter mine the character of the several series of observations.
