shadow appeared now round and uneven, felt only flat like the rest, and asked which was the lying sense, feeling or seeing? "Being shown his father's picture in a locket at his mother's watch and told what it was, he acknowledged a likeness, but was vastly surprised, asking how it could be that a large face could be expressed in so little room. "At first he could bear but very little sight, and the things he saw he thought extremely large; but, upon seeing things larger, those first seen he conceived less, never being able to imagine any lines beyond the bounds he saw. The room he was in he said he knew to be but part of the house, yet he could not conceive that the whole house could look bigger. Before he was couched he expected little advantage from seeing, except reading and writing. Blindness, he observed, had this advantage, that he could go anywhere in the dark much better than those who could see, and after he had seen he did not soon lose this quality nor desire a light to go about the house in the night. "A year after first seeing, being carried upon Epsom Downs and observing a large prospect, he was exceedingly delighted with it and called it a new kind of seeing; and now being lately couched of his other eye, he says that objects at first appeared large to this eye but not so large as they did at first to the other, and, looking upon the same object with both eyes, he thought it looked about twice as large as with the first couched eye only, but not double, that we can anywise discover." Remark on the First Case. Although this Chesselden case is the most famous of all, and the most frequently cited, it belongs, nevertheless, to those most inaccurately described. It is, however, not only the first in the order of time, but especially important for the reason that it demonstrates in a striking manner the slow acquirement of space-perception by the eye, and also the acquirement of the first and second dimensions of space (cf. vol. i, p. 57). II., III. THE WARE CASES. One of these cases is that of a boy, who at the age of seven years recovered his sight which he had lost in the first half-year of his life. The surgeon who performed the operation, James Ware, writes ("Philosophical Transactions of the Royal Society for 1801," ii, London, 1801, pp. 382-396):
