' In this work he reduced the study of what he called pure mechanics to a system. It is the earliest attempt to 

 develop, with anything like completeness, the science of machines considered from the kinematic point of view, without 

 reference to the forces which are at work or to the energy which is transmitted.'— D. N. B. 



Professor Willis, like Dr. Whewell, was one of the rare examples of a mathematician who cared for Pointed Architecture, 

 however natural, on its constructional side, such an interest might seem. His study however went far beyond Dr. Whewell's, 

 and he was, with Mr. Freeman, one of the ablest amateur authorities on English architecture, and his advice was of much 

 value in the restoration of many of the Cathedrals.

 ' In the present volume especial stress has been laid on the experimental side.' — Preface. It includes accounts of 

 numerous original expeiiments by the author, and is the most up-to-date text- book on its subject. The last chapter deals 

 with the Principle of Relativity.

Still the standard work on the subject. It must have been a great disappointment to German professors not to have 

 Louvamed the University of Riga.
