“ It is hardly necessary to say that the evidence as to the identity of the flame and comet spectra is almost overwhelming; the peculiar ill-defined appearance of the cometary bands at the time of the comet's greatest brightness is, however, something which I have not yet succeeded in imitating with the flame spectrum. The comet spectrum on July 25th certainly presented a general appearance quite different from that of the later observations, as regards the definition of the bands. ”

“ The spectrum of the nucleus was found to be for the most part simply continuous; but on several occasions, especially June 25, July 1, and July 12, it showed distinct bands, coinciding with those of the spectrum of the coma. When brightest the spectrum could easily be followed from the neighborhood of B to a point well above G ”

“ Art. XXV.—Spectroscopic Observations upon the Comet b, 1881; by Professor C. A. Young.
While the Comet was brightest the weather at Princeton was very tantalizing. From June 25 to July 3, the comet was seen and observed on every night except June 30, and on none of them, except July 2, more than an hour at a time, the work being invariably interrupted by clouds or fog. ”
