brilliant results, will come, if by the knowledge acquired of the 

 manner of the production of heart-trouble, we can prevent its 

 increase. The public, in the matter, err through ignorance, 

 and it is our place to show them that the heart will not, any 

 more than the brain, endure incessant and exhausting labor 

 and excitement ; that there are heart-weary as well as brain- 

 weary persons; to point out how some occupations predis- 

 pose to the disorder more than others, and how, therefore, 

 the dictates of science, humanity, and true econom}', alike de- 

 mand that they be less continuously pursued ; to make clear 

 to them that certain habits — such as bolting the food, and 

 constantly rushing after cars — may lead, indirectly or directly, 

 to consequences little thought of; and how it may be the heart 

 that bears the brunt of the irregularity and abuse, and not the 

 organs which would appear the ones most likely to suffer. 

 And you and I must make it part of our duty to impress these 

 truths, and thus to prevent those slight beginnings of ailment 

 which we both know may have grievous endings.
