“‘Philadelphia, Oct. 14, 1856.
“‘Dr. M. S. Perry:—
“‘Dear Sir,—It gives me much pleasure to reply to your note of inquiry concerning the health of Mr. Sumner.
“‘You are perfectly aware of the condition of Mr. Sumner when he reached this city on the 9th of July,—a condition of extreme nervous exhaustion, his circulation feeble, and in fact every vital power alarmingly sunken. At that time his steps were feeble and tottering, as in extreme old age; he complained of constant pain in the back and lower extremities,—in the latter it was a tired and weary sensation; and he had a sense of constriction and pressure about the head. At that time his pulse was quick and small, appetite languid, and his sleep broken, disturbed, and unrefreshing. All the above conditions were heightened by exertion, either mental or physical. I could find no evidence of organic disease. I understood Mr. Sumner to be in that state of extreme nervous exhaustion from which men are months, and at times even years, in being fully restored.
“‘Mr. Sumner has done eminently well. His present state is but a shadow of that above described; and although none of the features of the past are lost, they are only evident when imprudent exertion, mental or physical, shall call them up. Within the limits of exertion of an ordinary retired gentleman, Mr. Sumner improves daily, and all his powers improve, with a steady progress towards perfect health. Indiscretion brings on morbid wakefulness, and, in the recurring outline of his former condition, admonishes him, that, though recovering, he is still in risk.
“‘With much respect, truly yours,
“‘Caspar Wister.’
“LETTER FROM DR. JACKSON.[156]
“‘You ask for a brief report of the case of the Hon. Charles Sumner, as it came under my observation during his visit and stay on the Alleghany Mountain in Pennsylvania. Mr. Sumner came to Cresson on the 3d of August last. On his arrival, he had the appearance of a man who had been sick for a long time, and was still extremely unwell. Careful observations and examinations of the case, for some time, revealed the following appearances and symptoms.
