STATISTICS OF THE ROMAN CATHOLIC CHURCH.

Mr. Editor,—If any reader of your valuable and much-needed periodical can, through its medium, supply me with the title of some recent and authentic work containing Statistics of the Roman Catholic Church—e.g. the number of its members, or reputed members, in the different European States; the number and temporalities of its sees, clergy, &c.—he will confer on me a great obligation; one which it will be a pleasure to me to repay to some other "Querist," should it lie within my power to supply any desired information, in my turn. Your faithful servant,

E.E.
