"When I came to examine the address of the packet I observed that it was to Miss S. Cushing. Now, the oldest sister would, of course, be Miss Cushing, and although her initial was 'S.,' it might belong to one of the others as well. In that case we should have to commence our investigation from a fresh basis altogether. I therefore went into the house with the intention of clearing up this point. I was about to assure Miss Cushing that I was convinced that a mistake had been made, when you may remember that I came suddenly to a stop. The fact was that I had just seen something which filled me with surprise, and at the same time narrowed the field of our inquiry immensely. "As a medical man, you are aware, Watson, that there is no part of the body which varies so much as the human ear. Each ear is as a rule quite distinctive, and differs from all other ones. In last year's _Anthropological Journal_ you will find two short monographs from my pen upon the subject. I had therefore examined the ears in the box with the eyes of an expert, and had carefully noted their anatomical peculiarities. Imagine my surprise then, when, on looking at Miss Cushing, I perceived that her ear corresponded exactly with the female ear which I had just inspected. The matter was entirely beyond coincidence. There was the same shortening of the pinna, the same broad curve of the upper lobe, the same convolution of the inner cartilage. In all essentials it was the same ear. "Of course, I at once saw the enormous importance of the observation. It was evident that the victim was a blood relation, and probably a very close one. I began to talk to her about her family, and you remember that she at once gave us some exceedingly valuable details. [Illustration: "JIM BROWNER."] "In the first place, her sister's name was Sarah, and her address had, until recently, been the same, so that it was quite obvious how the mistake had occurred, and whom the packet was meant for. Then we heard of this steward, married to the third sister, and learned that he had at one time been so intimate with Miss Sarah that she had actually gone up to Liverpool to be near the Browners, but a quarrel had afterwards divided them. This quarrel had put a stop to all communications for some months, so that if Browner had occasion to address a packet to Miss Sarah, he would undoubtedly have done so to her old address.
