 pages have ever been written." — Liverpool Chamber of Commerce Journal,

 which he deals ; for he is not only Dean of the Liverpool School of Tropical 

 Medicine, but he has been the leader of some of the expeditions which that 

 School has despatched to tropical countries, . . . The natural histories of ail 

 the maladies referred to are well and succinctly stated by Sir Rubert upon 

 unimpeachable authority."— 7)^ Times. 



"Sir Rubert, writing with much lucidity and not a little spirit, follows the 

 course of medical research in the Tropics from strength to strength, accompanying 

 his narrative with many elucidatory statistics and a number of striking photo-
