[From the Temps, April 27, 1865.]

P. S.—Frightful news reaches us at the moment of going to press. President Lincoln has been assassinated; and an attempt has been made upon the life of Mr. Seward, but he survives. We wish we could doubt the correctness of these particulars, which, unfortunately, come to us in a form altogether affirmative.

We are not at all uneasy about the grandeur of the Union, nor in respect of American liberty. A ruined cause can never be sustained by crime, but every one will readily understand that the whole Union, in the south as in the north, is deeply wounded by the ball which has just carried off this great citizen in the midst of such critical circumstances.
