From the beginning of European trade and conquest overseas, Europeans
have known they died from the effect of the strange "climate." Later,
they came to understand that it was disease, not climate, that killed,
but the fact remained that every trading voyage, every military
expedition beyond Europe, had its price in European lives lost. For
European soldiers in the tropics at the beginning of the nineteenth
century, this added cost in deaths from disease--the "relocation
cost"--meant a death rate at least twice that of soldiers who stayed
home. This book is partly a statistical exposition of the changing death
rates of European Algeria, the British West Indies, and southern
India--by cause of death from disease--set against the comparable
figures for those who stayed at home in France or Great Britain. About
two-thirds of the book is devoted to a discussion of what Europeans at
the time thought about the possible causes of relocation costs and what
they did to remedy them in actual medical practice in the colonies.
