"So much for the string then," said Holmes, smiling; "now for the box wrapper. Brown paper, with a distinct smell of coffee. What, you did not observe it? I think there can be no doubt of it. Address printed in rather straggling characters: 'Miss S. Cushing, Cross Street, Croydon.' Done with a broad pointed pen, probably a J, and with very inferior ink. The word Croydon has been spelt originally with an i, which has been changed to y. The parcel was directed, then, by a man--the printing is distinctly masculine--of limited education and unacquainted with the town of Croydon. So far, so good! The box is a yellow, half-pound honeydew box, with nothing distinctive save two thumb marks at the left bottom corner. It is filled with rough salt of the quality used for preserving hides and other of the coarser commercial purposes. And embedded in it are these very singular inclosures." [Illustration: "HE EXAMINED THEM MINUTELY."] He took out the two ears as he spoke, and laying a board across his knees, he examined them minutely, while Lestrade and I, bending forward on each side of him, glanced alternately at these dreadful relics and at the thoughtful, eager face of our companion. Finally he returned them to the box once more, and sat for a while in deep thought. "You have observed, of course," said he at last, "that the ears are not a pair." "Yes, I have noticed that. But if this were the practical joke of some students from the dissecting-rooms, it would be as easy for them to send two odd ears as a pair." "Precisely. But this is not a practical joke." "You are sure of it?" "The presumption is strongly against it. Bodies in the dissecting-rooms are injected with preservative fluid. These ears bear no signs of this. They are fresh, too. They have been cut off with a blunt instrument, which would hardly happen if a student had done it. Again, carbolic or rectified spirits would be the preservatives which would suggest themselves to the medical mind, certainly not rough salt. I repeat that there is no practical joke here, but that we are investigating a serious crime." A vague thrill ran through me as I listened to my companion's words and saw the stern gravity which had hardened his features. This brutal preliminary seemed to shadow forth some strange and inexplicable horror in the background. Lestrade, however, shook his head like a man who is only half convinced. "There are objections to the joke theory, no doubt," said he; "but there are much stronger reasons against the other. We know that this woman has led a most quiet and respectable life at Penge and here for the last twenty years. She has hardly been away from her home for a day during that time. Why on earth, then, should any criminal send her the proofs of his guilt, especially as, unless she is a most consummate actress, she understands quite as little of the matter as we do?"
