In No. 439 of this Journal, Lieutenant Hunt received the credit of inventing a process by which copper-plate engravings may be transferred to stone, and the copies from a single print thus multiplied indefinitely. A correspondent, however, makes us fear that Lieutenant Hunt may have been unacquainted with what others had done before him. The process, it is stated, is not at all new; although, so far as we have heard, it has never been applied to the transfer of complicated pictorial engravings.
