Quite a change in the weather. Though the first day of winter, it is warm and pleasant. Have been to three hospitals with various articles, both of food and clothing. At the Baptist Church I saw a noble-looking man cold in death, who might have been living still but for the wicked experiment of a surgeon in probing his wound, and then injecting a substance which so irritated the nervous system that it produced convulsions, followed by lockjaw; and death, in a few hours, was the result. He was able to be about the ward at the time the probing was done, but from that moment he suffered the most excruciating pain, till death came to his relief. He leaves a wife and two children to mourn his untimely death. For the truth of this statement, I refer to Dr. Hammond--surgeon-in-charge--in whose absence the operation was performed, and from whom I learned the above facts. In St. Paul’s Hospital, among the many serious cases, there is one whose pale face and patient endurance of suffering have enlisted all my sympathy. This is a New York soldier, a beautiful young man of perhaps twenty-two summers. He has received a mortal wound in the body; life is slowly ebbing away, and he expects soon to receive a “starry crown, and robe of white.” _December 3d._ Among the hospitals visited to-day was St. Paul’s, where I had a quarrel with a surgeon. As I entered the hospital I met the doctor in one of the aisles. I saw at once there was something wrong, but not for a moment thinking that I was the “rock of offence,” when in an authoritative manner he demanded to know what I had in that bowl. “Tea, doctor,” was my reply. “Who is it for?” “That New York man over there; he can’t drink the tea made here, so I bring him some occasionally--any objections, doctor?” “I’ve no objections to the tea, but I don’t want _you_ to bring any more here.” Before I had time to reply, he had left the ward. As the poor fellow drank the tea, and returned the bowl--being weak and childish--he burst into tears and begged me to “come again,” while others expressed their regrets, saying, “The doctor is real mean to act so.” “Never you mind, boys,” said I; “I shall surely come again; the doctor and I will have a settlement, and we will find out what all this means.” I left the hospital, feeling deeply grieved at the rude treatment I had received; having given, to my knowledge, no provocation whatever. The evening after this unpleasant experience, I received a letter from my widowed sister, enclosing my brother’s photograph; also, a letter he had written a short time before he was wounded--the last ever traced by his dear hand for me. It was sealed and directed, but not mailed, having been found after his death in his diary and sent to his wife, who forwarded to me. The following is the letter, written only twelve days before the battle of Chantilly, where he received that fatal wound:
