Manuscript, 'Addendum to the note on the spectrum of Nova Aurigae' by Joseph Norman Lockyer Lockyer writes: 'On account of continued bad weather, no further photographs or observations of the Nova have been obtained since February 7. It then appeared to be slightly brighter than on February 3, when the star was first observed at Kensington. With the 10-inch refractor and Maclean spectroscope, C was seen to be very brilliant, and there were four very conspicuous lines in the green. Several fainter lines were also seen, and a dark line was suspected in the orange. I noticed that some of the lines, especially the bright one near F, on the less refrangible side, appeared to change rapidly in relative brightness, and this was confirmed by Mr Fowler.'
