Excerpt from The Motu Proprio Quantavis Diligentia and Its Critics The publication, on the 3oth of last December, of the letter mentioned on one of the first pages of this pam phlet,1 led to a necessarily discursive newspaper cor respondence in reference to the recent Motu Proprio. I think it advisable to put together here in permanent form, grouped under distinct and suitable heads, the more important of the points that came successively into prominence as the newspaper discussion went on. In doing this, I have introduced additional matter wherever I thought it would be useful for the purpose of illustration.
