Your last letter to us is dated at London, 7th. Octbr. It has given us all ample and sincere pleasure. The copy of your reply[47] to Mons. Waterton is excellent; that from Swainson ought to prove a death-blow to the Demerara Gent! I hope that these letters are now before the world, for my mortification has been great enough respecting the blackguardism of G. Ord and others, and yet I am heartily glad that I never paid personally any attention to them through the press or otherwise. Here my friends are as much shocked as myself, and the moment is at hand when these T... will be glad to find some hiding place to resort to, and wait for time to obliterate their obvious jealousy and falsehood. John Bachman and myself have begun a second series of experiments, such as I made before, connected with the nose-smelling of Turkey Buzzards; as far as we have gone through them, these experiments have proved _perfectly_ satisfactory to my good friend and myself, and depend [upon] it, from next Wednesday, the American World will know that Turkey Buzzards are first, Gregarious, as well as the Carrion Crow [Black Vulture], that they eat fresh meat in preference to putrid stuff; that they eat birds, fresh killed, either plucked or not, _even of their own species_; that they suck birds' eggs, and devour their callow young; that they come to their food by their sense of sight, and not that of smell, and lastly that they cannot discover by any sense of smell the most putrid matter, even when this putrid stuff is within a few feet of them, out of sight of their eyes. Were Snakes as abundant near Charleston as Buzzards, that business would soon be also set at rest, but for this, however, time is required, and the time I think will come. The experiments we are making will be repeated in the presence of the faculty of this city,[48] and their Certificates attached to the whole, and immediately published in the Annals of the Philosophical Society of Phila.[49] those of the Lyceum of New York. A copy will be sent to be read at the Linnean, or Royal Society of London, and Royal Institute of France; then let those laugh who win. We have attracted Turkey Buzzards with pieces of fresh beef, not more than an inch square, and we have seen others pass unnoticed the body of a hare or fowl within 20 steps. We have now 3 fine birds of this species to experiment upon, and their olfactory nerves will be examined by the faculty here, where there are some highly talented men.
