Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

In answer to a need for a comprehensive work on dynamics, this volume is reissued after having been out of print for over thirty-vie years. Physicists, advanced engineers, mathematicians, and teachers will find material in this classic which has been omitted from newer, more narrowly specialized texts. It also serves as an excellent source for the background essential to studies in motion, rocketry, aerodynamics, advanced dynamics, etc. A wide range of topics is covered in unusually great depth, applying the important tools of ordinary and partial differential equations. The author has included a special section on differential equations and the higher analysis which will prove helpful to students wishing to review these subjects.

This volume contains notes for 21 of the 22 major 16-mm sound films prepared under the direction of the NCFMF and covering nearly all of the fundamental phenomena of fluid motions.

Announcements for the following year included in some vols.
