This memoir is divided into four sections preceded by a preface in which Dr. Charles Wilcocks, Director, Bureau of Hygiene and Tropical Diseases, gives a most satisfactory biography of the author.

Section I: Historical, presents a survey of tropical medicine in 1898 which shows the times were ripe for the establishment of such a school. The author then describes the small beginnings from which, due to Sir Patrick Manson's firm lead, the backing given him by Mr. Joseph Chamberlain, Secretary of State for the Colonies and the munificent gift of the Rockefeller Foundation, the imposing school of today has evolved. As the history of the school proceeds Sir Philip keeps the reader abreast of the continuing development and great expansion of the field of tropical medicine, due in no small part to the unselfish devotion and unremitting labor of the men connected with the school.
