In the course of some inquiries into the affinity and structure of the Greek and Latin languages, I was led to analyse the superlative degree of both, and to trace, as I thought, some connection between it and the word Sublimis. While engaged in the investigation, I was naturally led to examine the common theories respecting the etymology of this remarkable word, and, in particular, the origin assigned to it by the late Dr Parr, and to weigh, with more attention than I had previously done, the arguments and proofs he had advanced in support of his opinions. All that I knew of them, till lately, was by verbal report, as I had not seen the abridged statement of them in an Appendix to the Notes of the 2d edition of Mr Stewart's Essays.
