This was a reply letter to W. Huggings kind letter of Sept.8th saying that it is very encouraging to know that our work here is appreciated by you. Then he wrote about radial motion in Sunspots, suggestion of Huggings in 1885, inclination of spectrum and finally climate conditions of Kodaikanal.

This letter was to inform John Evershed regarding holding the Pan-Pacific Science conference in Australia in August, 1923, and on behalf of the Council, the council desire to extend the invitation to the Madras Observatory.
