ORNITHOLOGY.—­An Indian boy brought me lately, the stuffed skin of a new species of bird, which appeared early in the spring at one of the sugar camps near St. Mary’s.  “We are desirous,” he adds, “to see the Fringilla, about which you wrote me some time ago.”

NATIVE COPPER.—­“The copper mass is safe, and the object of admiration in my collection.  Baron Lederer is shortly expected from Austria, when he will, no doubt, make some proposition concerning it, which I will communicate.”

29th.  Many letters have been received since the 13th of March, offering condolence in our bitter loss; but none of them, from a more sincere, or more welcome source, than one of this date from the Conants, of New York.
