Formerly, also, she was calm when she left him, not thinking of his
health, nor asking herself how she would find him at their next meeting,
strong and powerful, as sound in body as in mind. On the contrary, now
she worried herself, wondering how she would find him on the occasion of
each visit. Would the sadness, melancholy, and dejection still remain?
Would he be thinner and paler? It was her care, her anguish, to try to
divine the causes of the change in him, which manifested itself as
strongly in his sentiments as in his person. Was it not truly
extraordinary that he was more grave and uneasy now that his life was
assured than during the hard times when he was so worried that he never
knew what the morrow would bring? He had obtained the position that his
ambition coveted; he had sufficient money for his wants; he admitted that
his experiments had succeeded beyond his expectations; the essays that he
published on his experiments were loudly discussed, praised by some,
contested by others; it seemed that he had attained his object; and he
was sad, discontented, unhappy, more tormented than when he exhausted
himself with efforts, without other support than his will. At last, when
frightened to see him thus, she questioned him as to how he felt, he
became angry, and answered brutally

"Ill? Why do you think that I am--ill? Am I not better able than any
one to know how I am? I am overworked, that is all; and as my life of
privation does not permit me to repair my forces, I have become anaemic;
it is not serious. It is strange, truly, that you ask for explanations
of what is natural. Count the teeth of the polytechnicians and look at
their hair after their examinations, and tell me what you think of them.
Why do you think anything else is the matter with me? One cannot expend
one's self with impunity; that would be too good. Everything must be
paid for in this world."
