Mann, Charles Riborg, and Twiss, George Ransom. Physics. *$1.25. Scott.
5–33989.
In Professor Mann’s thoroly modern textbook, “intended for third or fourth year high school or freshman collegiate students ... he has abolished such problems as ‘let the forces a, b and c meet at the point q’ and substituted real concrete examples of the applications of physical formulae. He has substituted photographs of modern machinery, such as turbine engines, motors and loop-the-loop, for the antiquated and diagrammatic illustrations of the old text-books.” (Ind.)
“Professor Mann has made a special effort to make the student realize that physics is a practical subject and necessary to the understanding of the operations of daily life. Some of his pictures seem unnecessary and somewhat kindergartenish.”

Mann, Horace K. Lives of the popes in the early middle ages. v. 2 and 3: The popes during the Carolingian empire, Leo III. to Formosus, 795–891. ea. *$3. Herder.
These volumes “include a period of thirty-three years and six pontificates,—Popes in those days very seldom even approached the ‘annos Petri.’ This was the time of the ‘false decretals,’ and Mr. Mann is at great pains to show that the Popes with whom he is concerned did not use the evidence which these forgeries offered to support their claims.”—Spec.
“He has gone over his sources with painstaking care, and has thrown an extensive mass of historical erudition into an easy and well-ordered narrative. If there is anything in this volume against which one might feel inclined to utter an adverse criticism, it is the polemical note which strikes us as over-assertive in Father Mann’s pages.”
