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.

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.
