THE RELATION OF GEOLOGY TO DISEASE. 

 By G. W. Hawes. 



Mr. J. T. Gardner, in his address before the American Public Health Association at 

 Boston,* has drawn attention to the intimate connection between geology and health. 

 He indicates that controlling causes of some of our most fatal diseases are to be found 

 in local structural and lithological conditions, which are of even greater weight than 

 the condition of the air. In some regions above the palisades of the Hudson malarial 

 diseases are very prevalent. This region is underlaid by dense basaltic rocks, through 



Boston, October 6, 1876.
