I. Preliminary report of the joint solar eclipse committee of the Royal Society, the Royal Astronomical Society, and the solar physics committee on the observations of the solar eclipse of April 16, 1893

Abstract

The Joint Committee have requested me to make the following brief report on the observations of the Eclipse. This will be followed shortly by a more complete report. The Joint Committee was formed early in 1892, a grant of money was obtained from the Government Grant Fund of the Royal Society, and preparations were at once begun. After due consideration, it was decided to send out two observing expeditions, one to Fundium, on the Salum River, in Senegambia, and one to Pará-Curu, in the Province of Ceará, in the northern part of Brazil. With the exception of the work undertaken by Professor Thorpe, the whole of the observations were photographic. Three classes of work were undertaken at each station.
