They prove to be good steamers and tobe economical in fuel. Our readers will remember that at the AlexandriaBay convention of the Master Mechanics Associsi-. weight is distributed below through the standardsplaced at each end and terminating in knife edgeson the ends ot the levers 6 and 6, which are sup-ported at their centers by knife edges resting on asolid foundation c; the inner ends ot these levers band d support a disc d, and transmit the load on theplatform a through a rubber diaphragm c to a liquid /contained in the receiver g. which is rigidly con-nected to the foundation c. Through the upper partot the receiver g passes a pipe connected with theclose vessel h\ the lower part of this vessel containsmercury into which is plunged a barometric tube I,and the column ot mercury is forced more or less upthis tube with the weight upon the platform; thisweight can then be read off the graduated scale at-tached to the mercurial tube. It can be readily un-derstood how, by using a number of these platforms,the weights upon the different wheels may be readilyascertained. The following note concerning some current p
