In 1834, La Mennais published, under the title of _Affaires de Rome_, a report concerning his correspondence and relations with the Holy See. This was duly prohibited by the Congregation in 1835. _Le Livre du Peuple_, printed in 1837, was prohibited in 1838. The same course was taken with his later writings, appearing between 1841 and 1846. La Mennais died in February, 1854. The set of his works in five volumes, published after his death, 1855–1858, does not appear in the Index. =37. The Roman Revolution of 1848.=--The operations of the Index Congregation were not intermitted on the ground of the absence of Pius IX from Rome, from November 25, 1848, to April 12, 1850. During this period, three sessions were held in Rome and two in Naples, and judgment was passed upon a number of the more important of the publications of the day. Among those condemned the following titles may be noted: Rosmini, Antonio, _Die fünf Wünder der h. Kirche_, and _Die Verfassung gemäss der socialen Gerechtigkeit_. Gisberti, V., _Der moderne Jesuit_. Ventura, G., _Discorso funebre dei morti di Vienna_, etc. (The three titles in German are recorded in Italian.) A few months before the condemnation of the two treatises of Rosmini, his name had been under consideration with the pope for appointment as cardinal. His theological and philosophical writings had been denounced by his theological opponents as early as 1841, but, in 1843, Gregory XVI had ordered the controversies concerning the doctrines of Rosmini to be brought to a close. In 1850, the denunciation of the writings of Rosmini was renewed. The Congregation of the Index caused an examination of the works to be made by a number of consultors and, in 1854, the judgment was given that they were not to be disapproved, _dimittantur opera_. This continued controversy concerning the philosophical and theological teachings of Rosmini brought about, in 1880, an authoritative definition of the formula _dimittantur_.
