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. * * * * * CURTIUS.
