Wrist, if you please.--I was on his right side, but he presented his left wrist, crossing it over the other.--I begin to count, holding watch in left hand. One, two, three, four,----What a handsome hand!--wonder if that splendid stone is a carbuncle.--One, two, three, four, five, six, seven,----Can't see much, it is so dark, except one white object.--One, two, three, four,----Hang it! eighty or ninety in the minute, I guess.--Tongue, if you please.--Tongue is put out. Forget to look at it, or, rather, to take any particular notice of it;--but what _is_ that white object, with the long arm stretching up as if pointing to the sky, just as Vesalius and Spigelius and those old fellows used to put their skeletons? I don't think anything of such objects, you know; but what should _he_ have it in his chamber for?--As I had found his pulse irregular and intermittent, I took out a stethoscope, which is a pocket-spyglass for looking into men's chests with your ears, and laid it over the place where the heart beats. I missed the usual beat of the organ.--How is this?--I said,--where is your heart gone to?--He took the stethoscope and shifted it across to the right side; there was a displacement of the organ.--I am ill-packed,--he said;--there was no room for my heart in its place as it is with other men.--God help him! It is hard to draw the line between scientific curiosity and the desire for the patient's sake to learn all the details of his condition. I must look at this patient's chest, and thump it and listen to it. For this is a case of _ectopia cordis_, my boy,--displacement of the heart; and it isn't every day you get a chance to overhaul such an interesting malformation. And so I managed to do my duty and satisfy my curiosity at the same time. The torso was slight and deformed; the right arm attenuated,--the left full, round, and of perfect symmetry. It had run away with the life of the other limbs,--a common trick enough of Nature's, as I told you before. If you see a man with legs withered from childhood, keep out of the way of his arms, if you have a quarrel with him. He has the strength of four limbs in two; and if he strikes you, it is an arm-blow _plus_ a kick administered from the shoulder instead of the haunch, where it should have started from.
