This publication, though not a medical treatise, contains much data, observations and deduction, of the background of tropical medicine, considering the factors which make for success or failure of white colonization in the tropics.
A foreword suggests the timely appearance of this book when intolerance in Europe is forcing many refugees to seek homes in new environment; that science and improved communication are gradually converting white “sojourners” into “white settlers” with permanent homes in some areas of the tropics. The text is less hopeful of the availability for colonization of other areas.
This book is unusually comprehensive in its scope, not dealing with particular problems of specific regions but delving into historical, economic, social, administrative, medical, climatic, geological and geographical problems in many tropical and subtropical regions.
The scientific invaders of the tropics still face three great obstacles: disease, climate and the colored races.
