THIS volume is the most useful book in Mechanical Literature.
If constantly referred to will enable the student to acquire a correct knowledge of the words, terms and phrases in use in Mechanical Engineering and its various branches.
Its greatest value lies in this: that no man representing the mechanical profession can find excuse for not knowing the use and meaning of the terms used in his work.
