by tickling him on the soles of his feet, or by blowing a trumpet in his ears.” The history of Negretti was published separately by two physicians, Righellini and Pigatti, who were both eye-witnesses of the curious facts which they relate. “Negretti was about twenty-four years old, was a sleep-walker from his eleventh year; but his attacks only occurred in the month of March, lasting at farthest till the month of April. He was a servant of the Marquis Luigi Sale. On the evening of the 16th of March, 1740, after going to sleep on a bench in the kitchen, he began first to talk, then walked about, went to the dining-room and spread a table for dinner, placed himself behind a chair with a plate in his hand as if waiting on his master. After waiting until he thought his master had dined, he removed the table, put away all the materials in a basket, which he locked in a cupboard. He afterward warmed a bed, locked up the house, and prepared for his nightly rest. Being then awakened, and asked if he remembered what he had been doing, he answered no. This, however, was not always; he often recollected what he had been doing. Pigatti says he would awake when water was thrown into his face, or when his eyes were forcibly opened. According to Maffei, he then remained sometimes faint and stupid. Righellini assured Muratori that his eyes were firmly closed during the paroxysm, and that when a candle was put near to them, he took no notice of it. Sometimes he struck himself against the wall and even hurt himself severely. Hence it would seem that he was directed in his movements by habit, and had no actual perception of external objects. This is confirmed by the assurance that if anybody pushed him, he got out of the way and moved his arms rapidly about on every side; and that when he was in a place of which he had no distinct knowledge, he felt with his hands all the objects about him, and displayed much inaccuracy in his proceedings; but in places to which he was accustomed he was under no confusion, but went through his business very cleverly. Pigatti shut a door through which he had just passed; he struck himself against it in returning. The writer last mentioned was confident that Negretti could not see. He sometimes carried about with him a candle, as if to give him light in his employment; but on a bottle being substituted, took it and carried it, fancying that it was a candle. He once said during his sleep that he must go and hold a light to his master in his coach. Righellini followed him closely, and remarked that he stood still at the corners of the streets with his torch in his hand not lighted, and waited awhile in order that the coach which he supposed to be following might pass through the place where light was required. On the eighteenth of March he went through nearly the same process as before in laying a table, etc., and then went to the kitchen and sat down to supper. Signor Righellini observed him, in
