Section 17.

"Signature" or "subscription" includes mark when the signer or subscriber cannot write, such signer's or subscriber's name being written near the mark by a witness who writes his own name near the signer's or subscriber's name; but a signature or subscription by mark may be acknowledged or may serve as a signature or subscription to a sworn statement only when two witnesses so sign the same.
