              This item was about the measurements of spectrum and solar spots. It is divided into two parts. The first part describes the scale division of the spectroscope micrometer that defines the bright lines observed in the spectrum of the southeast by east prominence and the ordinary lines in the solar spectrum that were measured before and after the eclipse. The second part includes a sketch depicting the principal solar spots measured at Masulipatnam on August 18, 1868. The sketch shows four spots: A, B, C, and D.

              This fond contains collection of items that provide information about solar eclipses that occurred during the time period of 1868-2006. The collection includes photographs of total solar eclipses that took place on different dates, and covered from different places as well as sketches that help to illustrate the phenomenon and the path of the eclipses.

              Part of Compilation of Pogson's observations and drawing

              This item was about the Norman Robert Pogson in 1861. N.R. Pogson was appointed the government astronomer at Madras, India. When he arrived he had to work under harsh conditions. He found the instruments in a bad shape and there were no proper staff to assist him. In spite of all these he began a series of observations which terminated with his death 30 year later. He as credited with 50,000 observations most of which were published by Michie Smith after Pogsons death. During his stay in Madras he discoverd several minor planets and detected large number of variable stars. He named his daughters after the minor planets he discovered. He was also well known for his work in comets and solar eclipses.
