Referee's report by Robert Bellamy Clifton, on a paper 'Researches in spectrum-analysis in connexion with the spectrum of the sun - No. IV' by Joseph Norman Lockyer Recommended for publication in Philosophical Transactions. The paper seems 'more fit for the Proceedings yet it's scientific importance' gives it a claim to be in Philosophical Transactions instead. The paper is 'not by any means perfect from a literary point of view' and it should be edited before publication. Subject: Physics [Published in Philosophical Transactions, 1874]. 9 June 1874
