Drawings of the Sun for 4 October 1851 - 10 April 1860, showing sunspots, with positions of axis and equator, and usually also the Earth's longitude and position of ecliptic. The drawings of 1860 are delineated 'with a view to detecting Lescarbault's planet', with a note that nothing unusual was visible on the Sun's disc on 2 April 1860. There is a letter at the beginning from Airy to Robert Main, 29 January 1852, on procedure for observations.
