    Abstract

    THIS book opens with a very good discussion on the relations between movement and force; experimental evidence is obtained by use of a trolley and vibrator. Engineers' units are used freely, in which the unit of mass is g pounds. We are rather uncertain, however, as to what exactly the author wishes us to understand by. “1 lb. weight.” The poundal absolute unit of force is explained, and mention is made of the dyne, but the engineers' metric unit of force of one gram weight or one kilogram weight is not mentioned. There is a slip on p. 11, where, in dealing with momentum, W/g is described as lb., instead of engineers' units of mass. Despite these minor blemishes, this section of the book is a good deal clearer than many similar discussions in other text-books. Some very readable matter on hydrostatics and hydraulic appliances follows, illustrated by appropriate experiments. The chapter on materials will be useful in laboratories possessing but small equipment and under the necessity of using extemporised apparatus. The drawings of apparatus throughout the volume are such as to enable the appliances described to be constructed from them.
