On Thursday, Thanksgiving Day, Littlefield commenced operations with a hatchet and a chisel. Progress was slow, as that evening he had been invited to attend a festal gathering. On Friday the janitor, before resuming work, acquainted two of the Professors of the college with his proposed investigation, and received their sanction. As Webster, however, was going constantly in and out of his rooms, he could make little further progress that day. The Professor had come into town early in the morning.

Before going to the college he purchased some fish-hooks and gave orders for the making of a strong tin box with firm handles, a foot and a half square and a little more than a foot in depth; during the rest of the day he had been busy in his rooms until he left the college about four o'clock. Not till then was the watchful janitor able to resume his labours. Armed with a crowbar, he worked vigorously until he succeeded in penetrating the wall sufficiently to admit a light into the vault of the lavatory. The first objects which the light revealed to his eyes, were the pelvis of a man and two parts of a human leg.

Leaving his wife in charge of the remains, Littlefield went immediately to the house of Professor Bigelow, and informed him of the result of his search. They returned to the college some twenty minutes later, accompanied by the City Marshal. The human remains—a pelvis, a thigh and a leg—were taken out of the vault, and on a further search some pieces of bone were removed from one of the furnaces in the lower laboratory. The City Marshal at once dispatched three of his officers to Cambridge, to the house of Professor Webster.

To his immediate circle of friends and relations the conduct of the Professor during this eventful week had betrayed no unwonted discomposure or disturbance of mind. His evenings had been spent either at the house of friends, or at his own, playing whist, or reading Milton's "Allegro" and "Penseroso" to his wife and daughters. On Friday evening, about eight o'clock, as the Professor was saying good-bye to a friend on the steps of his house at Cambridge, the three police officers drove up to the door and asked him to accompany them to the Medical College. It was proposed, they said, to make a further search there that evening, and his presence was considered advisable. Webster assented immediately, put on his boots, his hat and coat, and got into the hired coach. As they drove towards the city, Webster spoke to the officers of Parkman's disappearance, and suggested that they should stop at the house of a lady who, he said, could give them some peculiar information on that subject. As they entered Boston, he remarked that they were taking the wrong direction for reaching the college. One of the officers replied that the driver might be "green," but that he would find his way to the college in time. At length the coach stopped. One of the officers alighted, and invited his companions to follow him into the office of the Leverett Street Jail. They obeyed. The Professor asked what it all meant; he was informed that he must consider himself in custody, charged with the murder of Dr. George Parkman. Webster, somewhat taken aback, desired that word should be sent to his family, but was dissuaded from his purpose for the time being. He was searched, and among other articles taken from him was a key some four or five inches long; it was the missing lavatory key. Whilst one of the officers withdrew to make out a mittimus, the Professor asked one of the others if they had found Dr. Parkman. The officer begged him not to question him. "You might tell me something about it," pleaded Webster. "Where did they find him? Did they find the whole body? Oh, my children! What will they do? What will they think of me? Where did you get the information?" The officers asked him if anybody had access to his apartments but himself. "Nobody," he replied, "but the porter who makes the fire." Then, after a pause, he exclaimed: "That villain! I am a ruined man." He was walking up and down wringing his hands, when one of the officers saw him put one hand into his waistcoat pocket, and raise it to his lips. A few moments later the unhappy man was seized with violent spasms. He was unable to stand, and was laid down in one of the cells. From this distressing state he was roused shortly before eleven, to be taken to the college. He was quite incapable of walking, and had to be supported by two of the officers. He was present there while his rooms were searched; but his state was painful in the extreme. He asked for water, but trembled so convulsively that he could only snap at the tumbler like a dog; his limbs were rigid; tears and sweat poured down his cheeks. On the way back to the jail, one of the officers, moved by his condition, expressed his pity for him. "Do you pity me? Are you sorry for me? What for?" asked Webster. "To see you so excited," replied the officer. "Oh! that's it," said the Professor.

The whole night through the prisoner lay without moving, and not until the following afternoon were his limbs relaxed sufficiently to allow of his sitting up. As his condition improved, he grew more confident. "That is no more Dr. Parkman's body," he said, "than mine. How in the world it came there I don't know," and he added: "I never liked the looks of Littlefield the janitor; I opposed his coming there all I could."

In the meantime a further examination of the Professor's rooms on Saturday had resulted in the discovery, in a tea-chest in the lower laboratory, of a thorax, the left thigh of a leg, and a hunting knife embedded in tan and covered over with minerals; some portions of bone and teeth were found mixed with the slag and cinders of one of the furnaces; also some fish-hooks and a quantity of twine, the latter identical with a piece of twine that had been tied round the thigh found in the chest.

Two days later the Professor furnished unwittingly some additional evidence against himself. On the Monday evening after his arrest he wrote from prison to one of his daughters the following letter:

"MY DEAREST MARIANNE,—I wrote Mama yesterday; I had a good sleep last night, and dreamt of you all. I got my clothes off, for the first time, and awoke in the morning quite hungry. It was a long time before my first breakfast from Parker's came; and it was relished, I can assure you. At one o'clock I was notified that I must appear at the court room. All was arranged with great regard to my comfort, and went off better than I had anticipated.

"On my return I had a bit of turkey and rice from Parker's. They send much more than I can eat, and I have directed the steward to distribute the surplus to any poor ones here.

"If you will send me a small canister of tea, I can make my own. A little pepper I may want some day. I would send the dirty clothes, but they were taken to dry. Tell Mama NOT TO OPEN the little bundle I gave her the other day, but to keep it just as she received it. With many kisses to you all. Good night!—From your affectionate
