Patent Office. According to the decision of the Supreme Court in O'Reilly v. Morse, (15 How., 121,) it might perhaps be supposed that I should go further, and, before any actual disclaimer, decree an account or order an issue quantum damnificatus. But I do not think that a court whose decision is liable to reversion, on appeal, should in such case make any decree beyond the perpetual injunction without an actual disclaimer, previously recorded in the Patent Office. In the present stage of the case, therefore, I can do no more than award the injunction with leave to disclaim, and afterward to move for such further order for an account, &c., as may be deemed proper." (3 Fish., 207.)

422. FORM OF DISCLAIMER.

To the Commissioner of Patents:

Your petitioner, Ichabod Willis, of St. Louis, county of St. Louis, and State of Missouri, represents that he has, by grant duly recorded in the United States Patent Office, (liber —, p. —,) become the owner of an exclusive right within and for the several States of Maine, New Hampshire, and Vermont, to make, use, and vend to others to be used, a certain improved mechanical movement, for which letters patent of the United States were granted to Jeremiah Ingersoll, of Albany, in the county of Albany and State of New York, April 1, 1869; that he has reason to believe that, through inadvertence, accident, or mistake, the specification and claim of said letters patent are too broad, including that of which said patentee was not the first inventor. Your petitioner, therefore, hereby enters his disclaimer to that part of the claim in said specification which is in the following words, to wit:

"I also claim the sleeves A B, having each a friction cam C, and connected, respectively, by means of chains or cords, K L and M N, with an oscillatory lever, to operate substantially as herein shown and described." ICHABOD WILLIS.

Witness: HENRY OAKLAND.

429. FINAL FEE TO BE PAID WITHIN SIX MONTHS, (vide supra, p. 343.)—The final fee on issuing a patent must be paid within six months after the time at which the patent was allowed and notice thereof sent to the applicant or his agent. And if the final fee for such patent be not paid within that time the patent will be forfeited, and the invention therein described become public property, as against the applicant therefor, unless he shall make a new application therefor within two years from the date of the original allowance. (Patent Office Rules, July, 1870; Act of July 8, 1870, § 35.)

430. How FEES MAY BE PAID.-The money for the payment of fees may be paid to the Commissioner, or to the Treasurer, or any of the assistant treasurers of the United States, or to any of the designated depositaries, national banks, or receivers of public money, designated by the Secretary of the Treasury for that purpose, who shall give the depositor a receipt or certificate of deposit therefor, which shall be transmitted to this office. When this cannot be done without much inconvenience, the money may be remitted by mail, and in every case the letter should state the exact amount inclosed. Letters containing money may be registered. Post-office moneyorders now afford a safe and convenient mode of transmitting fees. All such orders should be made payable to the Commissioner of Patents. (Patent Office Rules, July, 1870; Act of July 8, 1870, § 69.)

All money sent by mail, either to or from the Patent Office, will be at the risk of the owner. In no case should money be sent inclosed with models. All payments to
