Section 25 should be amended by inserting at the end of line 23 "and with intent to deprive the owner of the copyright of lawful profit." The word "willfully" does not appear to make the section sufficiently clear, and it is submitted that an infringer should not be held guilty of a misdemeanor unless he have the intent specified in the suggested amendment. After line 6 on page 19 the following words should be inserted: "_Provided_, That any person who performs the alleged infringing acts under a mistake of fact or law shall not be deemed to be a willful infringer." The alleged infringer may have good reason to think that conditions precedent have not been performed and that no valid copyright exists; he may be under a mistake as to when the term expires; he may be of the opinion that what he has produced is not a copy, and he may perform his alleged infringing acts under advice of counsel. It does not seem proper under such circumstances to hold him to be a willful infringer and guilty of a misdemeanor. In line 14 of page 19, after "knowingly," the following words should be inserted: "and with fraudulent intent." Page 20, line 9, before "publish," the following words should be inserted: "send notice of such seizure by registered mail to the person to whom the article seized is consigned or directed, and shall." Section 27, line 24, after "first," there should be inserted the words "mailing or". Section 29, lines 6 and 7, the words "supposed to contain" should be canceled, and the words "which contains" should be inserted. It is unreasonable to permit a postmaster to detain a package upon a mere supposition. In line 9, before "mail," there should be inserted the word "registered." Page 24, lines 16 and 17, the words "not more than one copy at one time" should be canceled, and in line 17 the word "or" changed to "and." At the end of section 32 the following should be inserted: "_Provided_, That the owner of the right to perform any copyrighted work by means of any automatic mechanical device shall not have the remedy by injunction herein provided until the amount of fair and reasonable royalty for such use shall have been ascertained by express contract between the parties, or by judgment of a court, and shall be due and not paid." Section 35, line 8, the word "full" should be canceled; and in line 9, after "allowed," there should be inserted "according to the practice of law and equity." In many cases it might be inequitable to allow costs, and the court should be left free to exercise its legal discretion.
