We are grateful to notice that Daguerreotypes are coming once more into vogue, as pictures taken by this process possess a depth, cleanness and delicacy which have not been attained by any other. Ambrotypes have more distinctness, and often much mellowness, as will be seen by the beautiful likeness of Miss Bradford, exhibited by Mr. McKenney, but lack the delicacy and truthfulness of the daguerreotype.
