Few text books are better known to medical men in the tropics than Manson's Tropical Diseases, which has been edited for many years now by Manson's son-in-law, Manson-Bahr, and which is now in its eleventh well deserved edition. Although not a large book—it runs to just over one thousand pages—it cannot easily be carried about by the tropical medical officer and there has long been a need for a pocket synopsis. With the passage of the war into the warm lands of the world and the unexpected entry into these warm lands of hundreds of medical men who must cope with problems unknown at home, the demand for a short synopsis has been enormously increased. This little text meets it. It is of a size which will easily slip into a tunic pocket. It contains an enormous mass of information, compressed into the smallest possible space and selected with the greatest care.
