Improved Pocket Chondrometer.

Directions for the Improved Pocket Chondrometer ; for 

 ascertaining the weights of all kinds of Grains, or 

 Farina. 



First, fill the measure, or bucket, in the same careful 

 manner you would do, if it were a real bushel ; and, with 

 the roll, strike off the top ; only observing, (as this in- 

 strument is upon a diminished scale, and that as the more 

 bearded, or rougher kinds of grain, such as oats, &c. are 

 more liable to be torn up by striking, than the smooth 

 and free,) that they should be charged somewhat heavier, 

 or they would lose too great a proportion, in so small a 

 quantity, by striking; and thereby appear too light. 

 Secondly, hook the bucket on the end of the scale-beam, 

 remove the brass slider to that part of the divided scale, 

 where it will just preponderate the bucket and its con- 

 tents. Then look at the fiducial edge' of the brass slider; 

 and observe at which degree it stands ; that being the 

 weight of an eight gallon bushel of the grain upon trial.
