delivered the opinion of the Court.

The appellant, Cleveland P. Manning, is the owner of a leasehold property in the City of Baltimore, known as No. 907 West North avenue. He and the appellee entered into a contract under seal for the sale and purchase of this property. The contract is here transcribed:

“This Agreement, made this 27th day of February, nineteen hundred and fourteen, between Cleveland P. Manning, of the City of Baltimore and State of Maryland, party of the first part, and T. Howard Embert, Attorney and Agent, of the City of Baltimore and State of Maryland, party of the second part:

“Witnesseth, that the said party of the first part does hereby bargain and sell unto the said party of the second part, and the latter doth hereby purchase from the former the following described property, situate and lying in in the City of Baltimore and State of Maryland, more particularly described as No. 907 W. North avenue, having a frontage of fifteen feet on North avenue and a depth of one hundred feet to a ten-foot alley, subject to an annual ground rent of One Hundred and Twenty ($120.00) Dollars, together with, the buildings and improvements thereupon erected, and the rights, ways and easements thereto belonging, or in any wise appertaining.

*547 “At and for tile price of Three Thousand Two Hundred and Seventy-five ($3,275.00) Dollars, of which $ One Hundred and Fifty have been paid prior to the signing hereof, and the balance is to be paid as follows: within sixty days from the date thereof.

“And upon payment as above of the unpaid purchase money, a Deed for the property shall be executed at the Vendee’s expense by the Vendor, which shall convey the property by a good and merchantable title to the Vendee.

“Witness our hands and seals.

Cleveland P. Manning. (Seal)

T. Howard Embert, (Seal)

Test: Attorney & Agent.

R. B. Pue,

As to both parties.”

Prior to the execution of this contract, the appellant had given the appellee three written options to purchase the property. In each of these options the appellee was designated as attorney and agent, and the appellant obligated himself “to sell and convey to T. Howard Embert, attorney and agent, or to any person or persons or corporations he may designate,” etc. The appellee refused to comply with the terms of the contract upon the ground that he was acting as attorney and agent for the Lord Calvert Theatres Company, a corporation which proposed to open a moving picture theatre or parlor, upon the premises, but by reason of objections on the part of property owners and others in the neighborhood the Mayor and City Council refused to- pass an ordinance permitting it to do so, and that he had informed the appellant before the execution of the contract that he was .acting in the purchase of the property as attorney and agent for the corporation. There were other defenses set up in the answer, but these were not supported by the proof and were not insisted npon in this Court.

*548 The appellant was ready, able and willing to comply with his obligations under the contract, and besides lost a desirable tenant for the property by reason of the failure of the appellee to perform the contract. He demanded that the appellee complete the purchase, and upon his refusal to do so filed a hill in Circuit Court No. 2 of Baltimore City for the specific performance of the contract. That Court dismissed the bill, and the plaintiff has brought this appeal.

The single question presented by the record is this: Is T. Howard Embert, the appellee, personally liable on the contract upon which this suit is based ? There is a broad and well defined distinction in the authorities between simple contracts and contracts under seal with respect to the personal liability of a person to the contract designating himself as agent, attorney, or in other representative capacity. The two classes of cases rest upon entirely dissimilar principles of law. Where one signs and seals an instrument by whicb he covenants to do certain things, the mere addition of the word “agent,” or other words indicating that he is acting in a representative capacity, does not change or vary the legal effect of his undertaking. If, by the terms of the instrument,, he imposes a personal liability upon himself it is his own covenant, and he is personally liable upon it. This is the Maryland rule and is supported by a practically unanimous current of authority. Stewart v. Katz, 30 Md. 334; Carroll v. Bowen, 113 Md. 150; Lutz v. Linthicum, 8 Peters, 165; Stewart v. Griffith, 217 U. S. 323; Stobie v. Dills, 62 Ill. 432; Hall v. Cockrell, 28 Ala. 507; Dayton v. Warne, 43 N. J. L. 659; Damon v. Granby, 2 Pick. 345; Huntington v. Knox, 7 Cush. 371.

It is undoubtedly trae that in simple contracts where the' principal is disclosed upon the face of the writing the agent is not bound, “unless it manifestly appears, by the terms of the instrument that the agent intended to superadd or substitute his own responsibility for that of the principal.” Key v. Parnham, 6 H. & J. 418; McClernan v. Hall, 33 Md. 293. Or unless the fact of agency or the identity of the prin *549 cipal is disclosed before or at tbe time tbe contract is entered into or before liability is incurred on either side. 2 Corpus Juris. 819.

In McDonough v. Templeman, 1 H. & J. 157, the name of the principal was disclosed in the contract itself. That, it is true, was a contract under seal, hut no opinion was filed, although it was stated “that the plaintiff in error acted as agent of the Georgetown Bridge Company, and did not by the contract make himself personally liable.

Mr. Poe in his work on Pleading and Practice, 3rd Edition, section 358, states the rule as follows: ' “Where the party sought to be held liable acted as a principal in his own name, the case is free from difficulty; but upon written contracts, made by agents, a question sometimes arises, whether the agents are themselves liable. This question is one wholly of interpretation. Where the contract is under seal, and executed by the agent in his own name, for himself and his representatives, the suit must be against him only, for he is personally bound by his covenant, although he describes himself in the deed as covenanting for, and on behalf of, another. In order to make a sealed instrument executed by an agent the act of the principal, so as to render the latter liable to suit thereon, it should be executed by the agent, in the name and under the seal of the principal, and not in his own name, and the authority to seal it as the act of the principal should itself he conferred upon the agent by an instrument under seal, which should be either annexed to the deed or particularly referred to in it. All deeds or other specialties executed by attorney, should, in the body, be described as the deed of the principal, acting by the attorney duly authorized by deed, and should be signed and sealed in the name of the principal by the agent. If not executed in this way, they will ordinarily be treated as the acts of the attorney or agent, and will subject him to a personal liability upon them.”

Tested by the principles of law applicable to the facts of this case there can be no doubt of Mr. Embert’s personal liability under the contract, and he must look to his princi *550 pal for protection. His principal is not disclosed by tbe contract and tbe Conrt must treat tbe contract as bis own personal obligation. It would appear to be now perfectly well settled that when a private agent does not attempt in a sealed instrument to bind bis principal and in terms imposes tbe obligation upon bimself be incurs by sucb act a personal liability, and tbe use of tbe words “agent” or “attorney” in tbe body of tbe instrument, or appended to bis signature, does not affect bis responsibility. Sucb designation will be treated as mere discriptio personarum. It was contended that tbe defendant informed Mr. Manning before tbe execution of tbe contract that be represented tbe Lord Calvert Theatres Co. If sucb a defense were admissible in this case, we would be obliged to bold that it is not sufficiently supported by tbe evidence. Our conclusion is that tbe plaintiff was entitled to tbe relief prayed for, and that tbe order of the lower Court passed on tbe third day of March, 1915, by which tbe bill was dismissed must be reversed, and tbe case remanded in orde'r that a decree may be passed in conformity to this opinion.

It may be proper to add that inasmuch as tbe contract was executed before Chapter 108 of tbe Acts 1914 (3rd Yol., Code, Art. 75, sec. 11 A1), became effective, tbe case is in no manner affected by tbe provisions of that Act.

Order reversed and came remanded, the costs to he paid hy the appellee.
