"My dear Manette, it is the case of an old and a prolonged shock, of great acuteness and severity to the affections, the feelings, the--the--as you express it--the mind. The mind. It is the case of a shock under which the sufferer was borne down, one cannot say for how long, because I believe he cannot calculate the time himself, and there are no other means of getting at it. It is the case of a shock from which the sufferer recovered, by a process that he cannot trace himself--as I once heard him publicly relate in a striking manner. It is the case of a shock from which he has recovered, so completely, as to be a highly intelligent man, capable of close application of mind, and great exertion of body, and of constantly making fresh additions to his stock of knowledge, which was already very large. But, unfortunately, there has been," he paused and took a deep breath--"a slight relapse."

     The Doctor, in a low voice, asked, "Of how long duration?"

     "Nine days and nights."

     "How did it show itself? I infer," glancing at his hands again, "in the resumption of some old pursuit connected with the shock?"

     "That is the fact."

     "Now, did you ever see him," asked the Doctor, distinctly and collectedly, though in the same low voice, "engaged in that pursuit originally?"

     "Once."
