[Footnote: In substantiation of this statement I need only cite the
recent contribution of my friend, Dr. Dana, on the "Partial Passing
of Neurasthenia."] The question has arisen whether the symptoms of
neurasthenia are always due to simple exhaustion. Advice regarding method,
as well as amount, of work, is coming into vogue. Peterson, in a letter
published in _Collier's Weekly_ (November 9, 1907) thus arraigns a patient
who has told him he is a practical business man, and that his mind has been
so occupied with serious matters that he has been unable to attend to his

with no appreciation of what it might represent if you were really serious
and really a business man or man of affairs. There are many like you in
our asylum wards, where they are known as chronic maniacs. Here is one who
collects bits of glass, old corks, and pieces of string. There sits another

Courtney (in Pyle's "Personal Hygiene") says, "The brain is an organ which,
under proper training, is capable of performing an immense amount of work,
provided only that the work is of a varied character and does not produce a
corresponding amount of mental disquietude. The importance of the emotions,
especially the depressing emotions such as grief, anxiety, and worry, as
factors in the brain exhaustion, cannot easily be overestimated."

The obvious corollary to this proposition is that the constitutional
