_Sir William Herschel_ (Vol. ii., p. 391.).--Your correspondent gives
the quotation about the star observed in Virgo, which he supposes
identical with Neptune, quite correctly, except in one very material
point--the observer's name. The passage in question will be found in
Captain W. H. Smyth's _Cycle of Celestial Objects_, vol. ii. p. 264.,
and is extracted from a letter addressed to him by M. Cacciatore of
Palermo, in 1835, many years after the death of Sir William. H. C. K. is
not the first person who has suggested the identity of the objects; but,
as pointed out by Captain Smyth in a paper on Neptune, in the _United
Service Journal_ for 1847, Part II., Neptune must, in 1835, have been
fully 120[degrees] from the position assigned by Cacciatore to the star observed
by him.
