“ T. R. H. Thomson, the surgeon, published, in two volumes, ‘A Narrative of the Expedition sent by H.M.'s Government to the River Niger in 1841.’ In 1849 he travelled through Syria and Palestine, and published the results in two volumes (1855) under the title of ‘The Dead Sea, a New Route to India, with other Fragments and Gleanings in the East,’ in which he advocated the construction of a canal between the Mediterranean and Red Sea by the Jordan Valley and Dead Sea, entering into elaborate comparison between that route and the proposed Suez Canal by the Nile. ”
