This great question of the Geography of Health and 

 Disease introduces the mind into a prolific arena of medi- 

 cal dynamics. " Man is a cosmopolite." He modifies the 

 agency of the elements upon himself, but those agencies 

 modify him. They have rendered him, in his organization, 

 different in different regions, physiologically, pathologically. 

 The great physical formula of natural elements, called "cli- 

 mate," is, as far as man is concerned, only the generalized 

 synthesis of the great librations or internecine warfare of 

 ponderable and imponderable. 



Reflect on the vastness of the problem the indigenous 

 diseases of climates ! It embraces the physiology and pa- 

 thology of geographic zones : as, the calorical boilings and 

 roastings of organs and tissues, of malarial poisons of such 

 intensity that they destroy tigers and snakes, and produce 

 congestive and quickly-destructive diseases in man, meta- 

 morphosing healthy organs into pools of disorganized 

 and dissolved blood, followed by infectious emanations, 

 which characterize the tropics ; also of plastic inflamma-
