Excerpt from Eclips Metrology and Allied Problems The following report on the operations of the United States Weather Bureau in connection with the observations of the total eclipse of the sun, May 28, 1900, is based upon the records of the expedition to' Newberry, S. C.; upon the special meteorological observations at sixty-two Weather Bureau stations located within 500 miles of the center of the track of totality; upon a considerable number of voluntary special observations executed within the belt of the umbra, in accordance with the instructions of the Washington office: and upon a study of various problems in solar and terrestrial meteorology. As the outcome of this work there have been made special studies, (1) on the apparatus planned to obtain a large-image picture of the inner corona, while yet employing a telescope of comparatively short focus; (2) on the shadow band phenomena, which appear to be due to meteorological conditions exclusively, and are not to be associated with diffraction on the edge of the moon; and (3) on the variations of the pressure, temperature, vapor tension, and wind caused by the passage of the shadow cone, together with a computation on the number of calories of heat absorbed per kilogram of air.
