Astronomer William Stephen Jacob of India made important advances in the study of Saturn. He made observations of the Sunnian system and reported his findings, which included determining the elements of Saturn's satellites and Jupiter's adjusted mass. In 1852, he and William Lassell observed the transparency of Saturn's "dusky ring" almost simultaneously. In 1861, James Breen truncated Jacob's planetary observations. The Indian government paid for the printing of his books on the Saturnian system. Important new information about Saturn and its moons was made possible by these observations and calculations. One of his best-known pieces is a sketch he made on November 15, 1852, of Saturn. Using the Madras Equatorial, this drawing was created. W. Forrest then etched it. The illustration caught the appearance of Saturn on that specific date, providing valuable insights into the planet's features and characteristics at that time.

This item was donated by Cherry Armstrong Great-Great Grand daughter of N.R.Pogson in 2006. We can see that Mr. Pogson was standing with Lucy Sylvia, An unknown Indian and Louise Camilla. Some small children were also seen in the photo seated infront, who probably be Charles Albion, Isis, and Robert Owen.

The cassette is about a one-day seminar on the world year of physics that is held at IIA Auditorium.

The Book On the discovery of The Periodic Law and on relations among the atomic weights written by John Alexander Reina Newlands was published in 1884. It has 70 pages.

The book was second edition of 'On the connexion of the physical sciences' written by Mary Somerville published in the year 1835. The book contains 494 (i-xvi) pages. The book describes about astronomy, physics, chemistry, geography, meteorology and electromagnetism as they were scientifically understood at the time.

This item was about the observations of thirty one variable stars observed by late N.R. Pogson. In this, he had described the different positions and observations with figured illustrations of variable stars.

This item was about the photograph of painting of Madras Observatory in 1792. It is considered as a postcard.

Observation summaries of July 28 to 31, Aug 1 to 19 and Dec 21 to 31.
