Excerpt from Elementary Treatise on Mechanics: For the Use of Colleges and Schools of Science IN accordance with the expressed wish of many teach ers in institutions where the Differential and Integral Calculus are either not taught at all, or else are not obligatory studies, an Appendix has been added to the body of the work, in which all of the principles there demonstrated by means of the Calculus are deduced by the aid of Elementary Mathematics only. It has not seemed desirable to omit the Calculus altogether, especially as by the present arrangement the work is equally adapted to the use of those who teach by the aid of the Calculus, and of those who only em ploy the Elementary Mathematics.
