For the benefit of science, and the coming generation, it is to be regretted that those who have his body in keeping, have refused a post-mortem examination.[3] Mr. Done-up, the chief physician, insists that he is not dead, and that he will have him kept for a year and a day, for experiments of the galvanic battery, electro-magnetic suspension, and such other inventions and restoratives as his skill may suggest. But it is the opinion of Wall-street physicians, that the doctor will never be able to do more than to embalm his body. DISEASE—ITS NATURE AND CAUSE. It is the opinion, also, of those who have had an opportunity of observing his symptoms, that his disease was a species of cholera, a sort of internal evacuation; or, to be more particular in explanation, that while promises were going out one way, the specie was going out the other; and that the too frequent gorging of stocks, state bonds, cotton speculations, &c., had the effect, like Major Downing’s elder-bark tea, to work both ways. One singular circumstance has attended him throughout; which, as it is a reversal of the order of nature, is worth mentioning. In his case, _corruption_ took place long before death, and _mortification_ afterwards. His disease is said to have had its origin in an overheating of the blood, in the great contest about the deposites. But as this is a matter of some dispute, I leave the point to be settled by the great successors of their “illustrious predecessors”—Dr. Done-up of Philadelphia, and Dr. Ran-down of Kinderhook, both of whom, it is supposed will now find sufficient leisure, amicably to settle their differences. PRACTICAL HINTS. My friend, the relator of the foregoing, here left me abruptly again, but as I am sure to find him in the same place to-morrow, I shall not fail to make him a visit. What the subject of his conversation will be, I cannot tell, but as he has found me a willing listener, I feel sure that he will be as communicative as ever.
