In a Latin letter addressed to Cardinal Patrizzi, and intended to come to the notice of the pope, Father de Buck repudiated the calumnies in a manner that betrayed how deeply he had been affected. His protest was supported by the testimony of four of his principal superiors, former provincials, and rectors who eagerly vouched for the sincerely of his declarations and the genuineness of his religious spirit. With the consent of his superiors he published this letter in order to communicate with those of his friends who might have been disturbed by these accusations.
