Referee's report by Henry John Stephen Smith, on a paper 'Introductory memoir on plane stigmatics' by Alexander John Ellis Not recommended for publication in the 'Philosophical Transactions of the Royal Society'. The term 'clinant' is new, but the concept is not. If the paper is, as suggested, the first in a series, then the current paper might be published as an introduction to the proposed future installments. Subject: Mathematics [Published in the Proceedings of the Royal Society of London, 1865] 14 September 1865
