"Still more remarkable are the results obtained by Doctor Bigelow in the saving of life and the lessening of suffering in the new method of operation for calculus. By the testimony of those renowned surgeons, Sir Henry Thompson and Mr. Erichsen, by the award to Doctor Bigelow of a sexennial prize founded by the Marquis d' Argenteuil, and by general consent, this innovation is established as one of the great modern improvements in surgery. I saw the numerous and patient experiments by which that priceless improvement was effected, and I cannot stop to moan over a scrap of integument, said to have been made imperishable, when I remember that for every lifeless body which served for these experiments, a hundred died or a thousand living fellow creatures have been saved from unutterable anguish, and many of them from premature death. "You will visit the noble hall soon to be filled with the collections left by the late Professor John Collins Warren, added to by other contributors, and to the care and increase of which the late Doctor John Jackson of precious memory gave many years of his always useful and laborious life. You may expect to find there a perfect Golgotha of skulls and a platoon of skeletons open to the sight of all comers. You will find portions of every human organ. You will see bones softened by acid and tied in bowknots; other bones burned until they are light as cork and whiter than ivory, yet still keeping their form; you will see sets of teeth from the stage of infancy to that of old age, and in every intermediate condition, exquisitely prepared and mounted; you will see preparations that once formed portions of living beings now carefully preserved to show their vessels and nerves; the organ of hearing exquisitely carved by French artists; you will find specimens of human integument, showing its constituent parts in different races; among the rest, that of the Ethiopian, with its cuticle or false skin turned back to show that God gave him a true skin beneath it as white as our own. Some of these specimens are injected to show their blood vessels; some are preserved in alcohol; some are dried. There was formerly a small scrap, said to be human skin, which had been subjected to the tanning process, and which was not the least interesting of the series. I have not seen it for a good while, and it may have disappeared as the cases might happen to be open while unscrupulous strangers were strolling through the museum. If it has, the curator will probably ask the next poor fellow who has his leg cut off, for permission to have a portion of its integument turned into leather. He would not object, in all probability, especially if he were promised that a wallet for his pocket or a slipper for his remaining foot, should be made from it.
