 of these instruments is new, and deserving of especial notice, as 

 it is the first successful attempt to register expended power.

 the same principle to the measurement of water ; evinces great 

 ingenuity and adaptation to the measurement of Ibiids, and the 

 recording of the same. [A gold medal awarded.

 adopted by the grain dealers and millers of the West as an accu- 

 rate and labor-saving machine. It not only performs its work, 

 but is a clerk to record its own labor.
