The machines on which the Jury of Class V. has had to ad-judicate are generally of the class called “Prime Movers,”being those more directly connected with the develop-ment of power than with its application. Where, how-ever, the application of the power to the result to beaccomplished is direct and immediate, the mechanicalexpedients by which it is made were also assigned to theconsideration of this Jury. Where the application isindirect, being made through a series of mechanicalelements intervening between the prime mover and thepoint where the result is accomplished, such interveningmachinery was reserved for the consideration of the Juryof Class VI.

It is obvious that in the consideration of this class ofmachines, the Jury must be chiefly guided by the prin-ciples of mechanics as distinguished from those of me-chanism. The machines referred to the Jury weredivided by the Commissioners into six classes, asfollows:—
