These Photographic slides contain some astronomical events of planetary nebula named NGC 2346 and NGC 6894 in Cygnus and the solar system and 10 billion years life cycle of our Sun. These slides look like negative photographs.

This item was about the discovery that was made by the Nobel physicists S Chandrasekhar and William A. Flower. It outlines the award was presented to Subrahmanyan Chandrasekhar and Flower for their distinguished work in astrophysics. The research involved the theoretical studies of the physical processes important to the structure and evolution of the stars by S Chandrashekar and the theoretical and experimental studies of the nuclear reactions of matter in the formation of chemical elements in the universe by William A. Flower. The prize was shared equally between the two of them. The article also mentions that the announcement of the award was made on S Chandrashekar's birthday, which is considered as a birthday gift to him for his Nobel work.

The letter was about discussion on Schwarzehildd calculation for gravitational field round a small particle.

This letter discusses for comments on real justification on Newtonian principles predictions.

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.

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.
