This letter was a reference to John Evershed letter that discusses regarding the spectral lines

The letter disusses on John Evershed's paper which was written 18 moths ago saying that he gone through the paper and a good deal about the factor 2 and the red-shift. A. S. Eddington said that he now more or less concerned that Einstein's theory is wrong on this point, and the true theoritical red-shift is twice his value as you find. Further he mentioned that the Thomas Royds confused him on the desirable value as the eclipse.

This letter was about the M. K. Vainu Bappu's application to National Institute of Science of India. A testimonial from Shapley on Bappu's professional knowledge in observational, analytical astronomy and astrophysics and his work in observatories.

This letter was about M. K. Vainu Bappu should undertake research on "Photoelectric Photometry of Eclipsing Variables".

The letter was a reply to A. S. Eddington acknowledging his work on redshift and his proposal to incorporate factor of 2 in the process. Further he mentioned about Thomas Royds results from the eclipse spectra.

This letter was about the appointment of Dr.M. K. Vainu Bappu as a "Teaching Fellow in Astronomy" for one year from July 1, 1950.

This letter was mentioning Sulaiman's excuse and agreeing with his prediction. Further he mentioned about Sulaiman's earlier papers and his "Chapter III".
