|Title||Paper, 'The spectrum changes in β Lyrae. Preliminary note' by Norman Lockyer|
|Description||Lockyer writes: 'The spectrum of this well known variable star was first investigated photographically by Professor Pickering, at Harvard College Observatory, and a preliminary account of the results was published in 1891. Dark and bright lines were found to be associated in the spectrum, and further, the bright lines were found to change their positions with respect to the corresponding dark ones according to the interval of time which had elapsed since the preceding minimum.'|
