' 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 exam pies 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. Whe well'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.

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

 with the Principle of Relativity.
