The title page of the first volume does not indicate volume numbering, the second volume, dated 1726, indicates Tome second; this is also a very first edition published as a sequel to the 1708 edition.

These letters deal with various subjects of piety and morality, on novices and how to guide them when they enter religious life, on death, on consolation in Jesus Christ, Lent, confession...
