PRESENTATION COPY OF THE FIRST EDITION FROM THE CO-AUTHOR, inscribed on half-title to 'Mr. Allum with Mr. Macqueen's best respects.' MacQueen first confronted Speke in a meeting of the R.G.S. in June 1859, questioning the accuracy of his quoted latitudes relative to vegetation. Speke was evasive and Macqueen's suspicions took root.
