are higher and narrower than those of their countrymen generally.  Both are lively and intelligent; they pay much attention to what is passing around them; and are very grateful for any little attention that is paid to them.  As a proof of their intelligence, it may be stated that they learned to play at Draughts very readily, and were soon able to beat those who had assisted in teaching them.  Their appearance is perfect health.  To their friends and attendants, and to each other, they are said to be much attached.  They appear to be excellent physiognomists, for they read the countenance of the visiter readily, and are easily affronted with any contemptuous expressions.  It is said they have not learnt any manual art beyond rowing a boat, but they can run and jump, and climb cracks and rigging with great facility.  They are dressed in short, loose, green jackets and trousers, the costume of their country, which is very convenient, and allows the utmost freedom of motion, but does not show the form of the boys to advantage.  With their arms twined round each other, as they bend down or move about, they look like a group of statuary.  Dr. Warren, in his report, states that he never heard them speak to each other, though they were very fond of talking with a young Siamese, who was brought with them as a companion.  They, however, appear to have a means of communication more rapid than by words.  The point most worthy of remark, in regard to their actions and movements, is, that they seem, generally speaking, to be actuated but by one will; and that from whichever of them the volition of the moment proceeds, it seems imperative upon both.  Occasionally, there is an exception to this remark—­as, on the voyage from Siam to the United States, when one wanted to bathe, and the other refused, on account of the coldness of the weather, they quarrelled on the subject.

Each has a name of his own—­the one, Chang, and the other, Eng; but, when persons wish to address them as one—­to claim their attention to anything, for example, or to call them—­they are addressed as—­Chang Eng.

The union of twins is not an unusual occurrence, and various anatomical collections present many such objects.  Ambrose Pare relates several instances.  Dr. Warren is, however, of opinion, that the Siamese Boys present the most remarkable case of the lusus naturae which has yet been known, taking into view the perfection and distinctness of organization, and the length of time they have lived.  The whole phenomenon may be described in a very few words—­two perfect bodies united and bound together by an inseparable link.  As we have already stated, their health is at present good; but, observes Dr. Warren, “it is probable that the change of their simple living for the luxuries they now obtain, together with the confinement their situation necessarily involves, will bring their lives to a close within a few years.”
