whether it could be safely divided? Upon examining the connexion, or cord, Dr. Warren says—"Placing my hand on this substance, I found it extremely hard. On further examination, the hardness was found to exist at the upper part of the cord only, and to be prolonged into the breast of each boy. Tracing it upwards, I found it to be constituted by a prolongation of the ensiform cartilage of the sternum, or extremity of the breast-bone. The cartilages proceeding from each sternum meet at an angle, and then seem to be connected by a ligament, so as to form a joint. This joint has a motion upwards and downwards, and also a lateral motion—the latter operating in such a way, that when the boys turn in either direction, the edges of the cartilage are found to open and shut.

      "Besides this there is nothing remarkable felt in the connecting substance. I could distinguish no pulsating vessel. The whole of this cord is covered by the skin. It is remarkably strong, and has no great sensibility, for they allow themselves to be pulled by a rope fastened to it, without exhibiting uneasiness. On ship board, one of them sometimes climbed on the capstan of the vessel, the other following as well as he could, without complaining. When I first saw the boys, I expected to see them pull on this cord in different directions, as their attention was attracted by different objects. I soon perceived that this did not happen. The slightest impulse of one to move in any direction is immediately followed by the other; so that they appear to be influenced by the same wish."

      This harmony in their movements, Dr. Warren thinks, is a habit formed by necessity. His further account of their habits is extremely curious:

      "They always face in one direction, standing nearly side by side, and are not able, without inconvenience, to face in the opposite direction—so that one is always at the right, and the other at the left. Although not placed exactly in a parallel line, they are able to run and leap with surprising activity. On some occasions a gentleman, in sport, pursued them round the ship, when they came suddenly to the hatchway, which had been inadvertently left open. The least check would have thrown them down the hatchway, and probably killed one, or both, but they leaped over it without difficulty. They differ in intellectual vigour; the perceptions of one are more acute than those of the other, and there is a corresponding coincidence in moral qualities. He who appears most intelligent is somewhat irritable in temper, while the other's disposition is mild."

      The connexion between these boys might present an opportunity for some interesting observations in regard to physiology and pathology. There is, no doubt, a network of blood-vessels and some minute nerves passing from one to the other. How far these parts are capable of transmitting the action of medicines, and of diseases, and especially what medicines and diseases, are points well worthy of consideration. Dr. W. thinks that any indisposition of one extends to the other; that they are inclined to sleep at the same time; eat about the same quantity, and perform other acts with great similarity. Both he and Mr. Hunter are of opinion that touching one of them when they are asleep, awakens both. When they are awake, an impulse given to one does not in the least affect the other. There is evidently no impression received by him who is not touched. But the opinion just mentioned is undoubtedly erroneous. The slightest movement of one is so speedily perceived by the other, as to deceive those who have not observed closely. There is no part of them which has a common perception, excepting the middle of the connecting cord, and a space near it. When a pointed instrument is applied precisely to the middle of the cord, it is felt by both, and also for about an inch on each side; beyond which the impression is limited to the individual of the side touched.

      "In the function of the circulation there is a remarkable uniformity in the two bodies. The pulsations of the hearts of both coincide exactly under ordinary circumstances. I counted seventy-three pulsations in a minute while they were sitting—counting first in one boy and then in the other; I then placed my fingers on an arm of each boy, and found the pulsations take place exactly together. One of them stooping suddenly to look at my watch, his pulse became much quicker than that of the other; but after he had returned to his former posture, in about a quarter of a minute his pulse was precisely like that of the other; this happened repeatedly. Their respirations are, of consequence, exactly simultaneous."

      Dr. Warren next starts a question as to their moral identity, and says—"There is no reason to doubt that the intellectual operations of the two are as perfectly distinct as those of any two individuals who might be accidentally confined together. Whether similarity of education, and identity of position as to external objects, have inspired them with any extraordinary sameness of mental action, I am unable to say—any farther, at least, than that they seem to agree in their habits and tastes." The concluding observation is on their separation, which we may remark, appears to be to them a painful subject; for whenever it is mentioned, they weep bitterly. Dr. Warren thinks an attempt to cut the cord, or separate them, would be attended with danger, though not necessarily fatal, and as they are happy in their present state, he reasonably enough thinks such an operation uncalled for. "Should one die before the other," adds he, "they should be cut apart immediately." He, however, quotes a case from Ambrose Paré, of two girls united by the forehead, one of whom died at ten years of age, when a separation was made; and the wound of the surviving girl soon proved fatal.

      From the report of Drs. Mitchill and Anderson, we collect their opinion that the band which joins these boys, has a canal with a protrusion of viscera from the abdomen of each boy, upon every effort of coughing or other exercise. The sense of feeling on the skin of this band is connected with each boy, as far as the middle of its length from his body. There can be no doubt, but that if the band was cut across at any part, a large opening would be made into the belly of each, and the wound prove fatal.

      Such are the principal and most popular descriptive details of the Siamese Youths, with the substance of the reports of the American physicians who have examined them. Of course, we look with some anxiety for the opinions of the professional men of our own country. Of equal importance are the questions connected with the minds of the two youths, which can only be settled by continued observation. The phenomenon is altogether of the most attractive character, and will doubtless receive all the attention it deserves from our savans, as well as from all those who delight in witnessing the curiosities of Nature.
