The exclusive right to deliver orally addresses and similar productions is now specifically included in the American law, as in the laws of some other countries, and probably involves the right to register, before publication, any literary production intended for oral delivery before it is printed in a book or periodical. Thus if Mr. Cable desires to include in his readings, especially if in public for profit, chapters from an unpublished novel, or a poet desires to protect his copyright in a poem which he publicly recites, it may be desirable that he should register such unpublished work under the provisions of the act for that purpose; although it is a generally accepted doctrine that oral delivery does not constitute publication, and that the matter orally delivered may thus be protected at common law. {Sidenote: "Publicly and for profit"} It should be noted that in the case of a lecture or other work for oral delivery and of a musical composition, the exclusive right is given for its delivery or performance "publicly and for profit," and in the case of a drama, "publicly," the words for profit being, probably by inadvertence, omitted. There is some question, therefore, whether a copyrighted lecture, drama, or musical composition can be given without consent of the author privately, or, except in the case of a drama, gratuitously before the public. In view of the special exception (sec. 28) exempting oratorios, etc., performed for charitable or educational purposes and not for profit, from authorization or payment, as well as on general principles of construction, it would seem probable that the courts would protect the author of a lecture, drama, or musical composition, except in such instances as a private rendering in a private house, to which there was not public admission and at which no fee was charged or collection taken. The cases bearing on this point are given in the later chapter on dramatic and musical copyright. {Sidenote: Material and immaterial property} The American code adopts into the law an important distinction as between the property in the material and the immaterial rights, hitherto somewhat uncertain, in the following provision (sec. 41): "That the copyright is distinct from the property in the material object copyrighted, and the sale, or conveyance, by gift or otherwise, of the material object shall not of itself constitute a transfer of the copyright, nor shall the assignment of the copyright constitute a transfer of the title to the material object; but nothing in this Act shall be deemed to forbid, prevent, or restrict the transfer of any copy of a copyrighted work the possession of which has been lawfully obtained."
