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 item was about the hand-colored picture of the Sun, as observed by N.R. Pogson at Masulipatnam with the Smythian five-foot Telescope from the Hartwell observatory, which has a power of 52. In the picture, Pogson has made two sketches of the solar eclipse, explaining how the Sun was seen immediately after the disappearance and how it was seen immediately before the reappearance.

This item was about total solar eclipse of 18th August 1868. At Masulipatnam Pogson detected the hydrogen line emission, with a spectroscope. He saw a bright yellow line near the position of D lines of Sodium. The line originated from hitherto unknown element later termed as helium after the source of earliest detection. Hand coloured sketch of the solar spectrum during the Total Solar Eclipse of 1868. Hand coloured picture of the sun before and after the total solar eclipse 1868.
