Telescopic Appearances of Donati's Comet, as seen from the Cambridge Observatory, Sept. 25, 7.30p.m, 1858. 'As it but seldom happens that such a favourable opportunity occurs for examining the changes which take place in the head and nucleus of a large comet approaching to and receding from the sun as in the magnificent object which has just disappeared from sight, a few particulars respecting those may not be misplaced in the columns of the Illustrated London News...On Sept. 25...the luminous sector had become greatly expanded, and was completely merged into the head, which was now much broader. The nucleus on this occasion had a bright planetary disc, and appeared to show a phase as if half-full'. From "Illustrated London News", 1858.
