It may be repeated, to make the list complete, that by the ratification in 1908 of the Mexico City convention of 1902, Guatemala, Honduras, Nicaragua and Salvador, as well as Costa Rica, have reciprocal copyright relations with the United States, making in all twenty-four countries (including Japan under the treaties excepting translations, and China under the limited provisions of the treaty of 1903) with which the United States has international copyright relations. XIX THE INTERNATIONAL COPYRIGHT MOVEMENT IN AMERICA {Sidenote: Initial endeavor in America, 1837} Simultaneously with the earliest legislation for international copyright among European states, there was a movement in the same direction in the United States. In the Twenty-fourth Congress, February 2, 1837, Henry Clay presented to the Senate an address of British authors asking for copyright protection in this country. This petition was signed by Thomas Moore and fifty-five others, and was later supplemented by additional signatures and by an American petition to the same effect. {Sidenote: The British address} The text of the address is as follows, the reference in paragraph seven being to a letter by Dr. M'Vickar, printed in the New York _American_, November 19, 1832: "The humble address and petition of certain authors of Great Britain, to the Senate and House of Representatives of the United States, in Congress assembled, respectfully showeth-- "1. That your petitioners have long been exposed to injury in their reputation and property, from the want of a law by which the exclusive right to their respective writings may be secured to them in the United States of America. "2. That, for want of such law, deep and extensive injuries have, of late, been inflicted on the reputation and property of certain of your petitioners; and on the interests of literature and science, which ought to constitute a bond of union and friendship between the United States and Great Britain. "3. That, from the circumstance of the English language being common to both nations, the works of British authors are extensively read throughout the United States of America, while the profits arising from the sale of their works may be wholly appropriated by American booksellers, not only without the consent of the authors, but even contrary to their express desire--a grievance under which your petitioners have, at present, no redress. "4. That the works thus appropriated by American booksellers are liable to be mutilated and altered, at the pleasure of the said booksellers, or of any other persons who may have an interest in reducing the price of the works, or in conciliating the supposed principles or prejudice of purchasers in the respective sections of your union: and that, the names of the authors being retained, they may be made responsible for works which they no longer recognize as their own.
