446 Longevity of Brain-Workers. [October, 
the command of a man who, I am sure, worried and exhausted 
himself more over that little craft than did Admiral 
Farragut over the entire squadron. When he died, shortly 
after the close of the war, I was requested by his widow to 
use my influence in procuring a pension for her. This I 
was able to do most conscientiously, for I knew that he had 
worn himself out in the service, although the vessel under 
his charge, while I was on board at least, never went into 
action, chased no blockade runner, and experienced not one 
moment of real peril. 
5. The advantages that belong to the brain-working orders in 
general. Of these I have already spoken in some detail. 
The great brain-workers of the world have not all been rich ; 
neither have they all been poor; some of them have lived a 
portion of their lives, but very few all their lives, in extreme 
want; and the majority have been most of the time sur- 
rounded with at least moderate comforts. 
Causes of the Great Longevity of Clergymen. 
When, in 1867, I first called attention to the fact that 
clergymen were longer lived than any other class of brain- 
workers, serious doubt was expressed whether there might 
not be some error in my statistics. So much had been said 
of the pernicious effects of mental labour, of the ill-health 
of brain-workers of all classes, and especially of clergymen, 
that very few were prepared to accept the statement that the 
clergy of this country and of England lived longer than any 
other class, except farmers, and very naturally suspected a 
lurking fallacy. Other observers, who have since given 
special attention to the subject, have more than confirmed 
this conclusion, and have shown that clergymen are longer- 
lived than farmers. 
The Rev. Josiah F. Tuttle, D.D., President of Wabash 
College, Indiana, has ascertained the ages of 2442 clergy- 
men—6oo Trinitarian Congregationalists, 317 Presbyterians, 
231 Episcopalians, 268 Baptists, 208 Methodists, 166 Uni- 
tarians, &c.,—and found that the average was “‘a little over 
61 years.” ‘‘ Considerably over one-half of the whole were 
over 60 years of age at their death; three-fourths of the 
whole were over 50 years old at death; and seven-eighths 
of the whole were over 40 years of age at death.” Dr. Tuttle 
found that the average age at death of 408 individuals (not 
clergymen), and who had died over 21 years of age, was a 
little over 51 years. This result pretty nearly corresponds 
with mine. 
But by far the more thorough investigation on this subject,
