The dyspepsia was, as far as I know, of a very ordinary kind. It began with loss of appetite, discomfort after meals, and general sense of weakness and uselessness. Then came a crisis. Waking in the middle of the night with pain and nausea, an hour or two of this, thorough evacuation of the stomach, great discomfort next day, and then no symptom of any thing wrong as long as I adhered to the diet which experience soon led me to, viz., very simple food and very little of it. To this I adhered for about four weeks. Now and then, perhaps three times altogether, feeling quite well, I ventured to eat like other people, and was at once taught by abdominal pain and diarrhœa, that I must still consider myself an invalid, or at best a convalescent.
