Life with Boswell

Boswell and Dr Johnson met young Mackinnon upon their arrival on Raasay on September 8, 1773. Boswell described him as "a young man of small size, delicate constitution, feebleness of voice and nearness of sight, but I was told had great knowledge, and hurt himself by too much study, particularly of infidel metaphysicians."
