The item contains data on the meantime of the Moon in 1864. Observations result from January to December are tabulated in this note.

The item contains observation notes titled 'approximate places of star reduced to' from 1825 to 1868 by N. R. Pogson. The documents have the observation notes of minor planets: Hestia, Asia, Iris, Europa, Thalia, Alexandra etc.

The item contains observation notes titled 'Madras zone reduced to' from 1825-1867 by N. R. Pogson. The documents have the observation notes of minor planets: Hestia, Sylvia, Sappho, Camilla, Iris, Ariadne, etc.

The notes are used to determine the apparent polar distance of the stars. The records contain observations of seven stars, including Polaris, Draconis, and Cephei.

The note includes information about planet observation between 1862 and 1865. Around 29 planets have had their observations recorded.

The item comprises observations made as Madras Equatorial Observations of transit of Mercury occurred on the 11th and 12th of November 1861 by N.R. Pogson. The document contains observational data and critical notes about the astronomical event. Mercury's transit across the Sun occurs when the planet Mercury passes directly between the Sun and a superior planet.

The item contains Madras equatorial observations of the occultation of Venus that occurred in three different dates; 18 July, 1865, 3 November 1872 and 2 may 1875 recorded by N. R Pogson from Madras Observatory.

The letter is from the Director General of stores to Charles Michie Smith regarding volumes of the mural circle and transit observations. It consists of a copy letter from the Royal Astronomical Society and a list of 6 folio volumes presented to the Royal Astronomical Society.

The letter was a appreciation for John Evershed discovery of spectral shift of light from the edge of the solar disc is really double of Einsteins's value. He mentioned about failure of Einstein's relativity. Further he provided 6 points on Newtonian principles, equation for the motion of a light, spectral shift of light.

The letter discusses on comparison on graphs that gives the difference between the shift of line at the various points, and the shift at the centre to be compared with his formula. At the backside of this letter S. M. Sulaiman's handwritten explained the formula.
