A formula which finds place in the Index first under Benedict reads: _Auctor laudabiliter se subjecit et opus suum reprobavit_. When a work has been condemned by the Inquisition or by the Congregation on the ground of heretical propositions, the determination of such propositions is based upon certain general principles laid down by the Inquisition. The author has the alternative of cancelling the book altogether or of agreeing to reprint it with the elimination of the propositions condemned as heretical. In later years, it has been the practice of the Congregation in the case of authors to whom, on one ground or another, it is thought desirable to extend consideration, to give to such authors, in advance of the publication of any condemnation, the opportunity of making the eliminations or corrections required. If the author promptly assents to such a course, his work is not included in any of the official lists of condemnation. Catholics who learn first through the publication of the official reports that their writings have come into condemnation and who thereupon make submission and promise of correction, are recorded in a supplementary decree of the Congregation. Such decree makes announcement of the fact of the submission and gives approval to the text as corrected, of the work in question. The form of announcement is as follows: _Auctor laudabiliter se subjecit et opus reprobavit_. In the case of works which have been prohibited with a _d.c._ the formula reads: _Auctor laudabiliter se subjecit et reprobanda reprobavit_ or _et opus amendavit_. There are various examples of the use of this formula between the years 1873 and 1881. In a decree of Pius IX, issued in June, 1848, the censorship concerning material of a religious or doctrinal character, printed either in books or periodicals, was restricted to the territory of the States of the Church. A decree of the inquisitor-general, issued in September, 1851, states: “It is become known to us that either on the ground of malice, of wilful disobedience, or of ignorance, certain persons fail to give information to the Holy See concerning the undertakings of heretics and the spread of Protestant contentions, or concerning the publication of attacks or satires against the Pope or against ecclesiastical Orders, or as to the distribution of writings in which the Holy Scriptures have been misused or misquoted, or the distribution of works printed without the official permit, or the reading, printing or possession of such works. It is hereby ordered that all such delinquents shall incur the penalty of excommunication _latae sententiae_. This edict is to be placed in every sacristy. It is further ordered that all printers, booksellers, collectors of customs, janitors, landlords, and shopkeepers of any kind shall place copies of this edict in their premises in such manner that it shall be read by all.”
