as soon as he should be able to get into the fresh air of the 
country, and face to face with Nature, which he so dearly loved 
from his earliest childhood. In his letter to his aunt, the last 
he wrote, and only two weeks before his death, one sees this 
optimism. He does not propose to die just yet, looks upon 
health as the greatest of blessings, is glad that so many pos- 
sess it; thinks the enforced break in trying occupations turns 
one's thoughts to other and necessary subjects, and is pre- 
pared to die — when the time comes — in the settled conviction 
that it will be a change for the better. This letter is a touching 
and fitting farewell of a great mind to a world in which he had 
accomplished a gigantic work.
