The ground of objection, or the reasons influencing the court to the exclusion of the mortgage, accompanied by evidence of its actual execution, are not stated in the bill of exceptions, The sufficiency and fairness *295of its consideration does not appear to have been matter of dispute; and if it had been, it would not have justified its exclusion as evidence, whatever instructions to the jury may have been required in reference to it. Prior in point of time of execution, and of registration, if valid and operative as a conveyance, it passed to the defendant a title superior to that created by the mortgage to the plaintiffs, and was a full defense to the present action. The only ground of objection suggested by the argument of counsel, to its admissibility as evidence, is the manner of its execution — that the mortgagors sign by mark only, and their signatures are not attested by a subscribing witness, nor were they acknowledged before, and certified by, an officer having authority to take and certify the acknowledgment of conveyances. The objection is founded on the definition of the words “signature” or “subscription'''' given by the first section of the Code. This and several succeeding sections declare the meaning of particular words used in the Code; and among others it is said: “ Signature, or subscription, includes mark, when the person can not write; his name being written near it, and witnessed by a person who writes his own name as a witness.”
A subscription or signature to any instrument by mark, at common law, is sufficient; and if it is not an instrument, the execution of which must be attested by a witness or witnesses, the absence of an attestation would not detract from its sufficiency, though proof of execution, when it becomes necessary to prove it, is thereby rendered more difficult.—Baker v. Dening, 8 Ad. & Ell. 94; 3 Wash. Real Prop. 244; Wimberly v. Dallas, 52 Ala. 196; Bailey v. Bailey, 35 Ala. 687. The statutory provision we are considering does not negative expressly the validity of instruments signed or subscribed by mark, and not attested; yet, as it introduces a new rule in reference to subscriptions or signatures, we think it must be construed as implying a negative of the sufficiency of unattested signatures or subscriptions by mark, of all instruments falling within its purview. When a statute limits a thing to be done in a particular manner, it includes in itself a negative; and the negative is, that it shall not be done otherwise. The limitation exists, whenever the statute prescribes the particular manner in which the thing must be done. — 1 Kent, 467, marg. note; Sedgwick’s Stat. & Const. Law, 31; Potter’s Dwarris, 72. On this principle, we held in Hendon v. White, 52 Ala. 597, and in subsequent cases, a conveyance of lands is not effectual to pass the legal title, unless attested by one, or, where the grantor can. not write, by two witnesses, or acknowledged before a proper officer. Such are the requisitions of the statutes. They define the *296constituents of a conveyance of lands; but they do not define the constituents of any conveyance of personal property, ■whether it is absolute or conditional. That such conveyances may, and will in the course of the transactions of the community, be made, and will be in writing, the statutes recognize, and authorize the registration of such conveyances in particular instances. The mode of executing them— whether they shall be under, or without seal • what shall be the operation of any covenant they containthe manner of subscribing or signing them, nor any other constituent of their creation, is defined or declared. The manner of creating such conveyances, or of making transfers of personal property, is controlled entirely by the common law.
The statutory definition of signature or subscription is limited to these words when used in the Code, and to instruments or contracts, which the Code, or some statute not incorporated in it, requires to be signed or subscribed. The agreements which, under the statute of frauds, are void if not in writing, must be subscribed by the party to be charged, or some other person by him thereunto lawfully authorized in writing. There are other instruments, also, required to be subscribed or signed. To all these, the statutory definition of subscription or signature extends. It does not extend beyond the use of the words in the Code, or in other statutes which must be construed as if they were a part of it. Contracts, or instruments, the constituents of which are to be ascertained wholly from the common law, are not included by the language of the statute, nor in its spirit or, purpose. The mortgage, though executed by mark only, and not attested by witnesses, was a valid conveyance. The title to personal property may pass with or without writing; and if by writing, witnesses to its execution are not essential. —Morrow v. Turney, 35 Ala. 131.
Mortgages of personal property, to be operative against subsequent purchasers, or creditors without notice, must be recorded. Proof of their execution, or an acknowledgment of it, is not indispensable to registration. It may be made without either, and operates as notice of their contents.— Code of 1876, § 2153. The registration of the mortgage to the defendant was properly made, and affected the plaintiffs with notice of its contents. The Circuit Court erred in not permitting it to be read in evidence, on proof of its execution. It is not necessary to notice any other of the rulings of the court, as they may not arise on another trial.
The judgment must be reversed, and the cause remanded.
