Paper, 'On supersaturated saline solutions' by Charles Tomlinson Tomlinson provides a definition of supersaturation followed by a 'historical sketch' of research on the subject, noting that the phenomena of supersaturation have been studied chiefly with reference to solutions of Glauber's salt [sodium sulphate]. He goes on to discuss in detail the action of nuclei, the formulation of the modified salt. Note on front reads 'The paper published in Phil Trans is a revised condensation of this.' Followed by an appendix dated 13 August 1868. Subject: Chemistry Received 21 May 1868. Read 28 May 1868. A version of this paper was published in volume 158 of Philosophical Transactions as 'On supersaturated saline solutions'. 18 April 1868-13 August 1868
