This item was about the 1977–1978 UGC Hari Om Trust awards. M.K.V. M. K. Vainu Bappu, an IIA scientist, was also one of the recipients of awards on this list. Along with him many scientists from different fields were also the recipent of this award as mentioned.

This letter was about M. K. Vainu Bappu's critical condition after undergoing heart by-pass surgery at Munich's University Clinic.

This item was about the French Father Richaud made the first astronomical discovery on Indian soil. In 1689, when he discovered the double star Alpha Centauri using a 12-foot telescope in Pondicherry. He also determined the latitude and longitude of Pondicherry.

This item was about the description of minor planet named as 87 Sylvia. This was discovered on 16th May 1866 by N.R.Pogson. The comparison stars employed have all been observed with the Meridian Circle of the Madras Observatory.

Fond provides a comprehensive overview of microscopy, covering introductory concepts and various aspects, including lenses and light phenomena. It delves into the construction, theory, and practical use of microscopes. Beginning with a historical perspective, it navigates through the significance of lenses and optics, shedding light on the interplay between light and microscopic observation. Detailed discussions on microscope construction and theoretical foundations are included.

The fond contains observations of the meridian circle reductions ( refers to the process of correcting the observed zenith distances measured by a meridian circle instrument ) taken from the Madras Observatory from the year 1862 to 1887. Meridian circle reductions refers to a process in astronomy and celestial navigation that involves observations made with a meridian circle instrument.
