(§. 22.) The Cube weighed in distilled Water. 
Sept. 5. Put into the left scale, the counterpoise f 300 1 s fains - 
for the water scale - - { 100 j ' 4 00 j 00 
The cube, with its scale, was then immersed in the water* 
I then restored the equilibrium, by putting into the 
opposite or left-hand common scale, Mr. Trough 
ton's weights, No. 10. 
(The barom. standing at 29,47 inches, 
the therm, at 6o°,2.) 
But a counterpoise of 
4 °° 
grains.

having been taken, by mistake, instead of 442,75 l_ , ^ 
Deduct the difference, whi ch was so left 0^=42 ,75 j — 
The apparent weight of the cube in water becomes = 702,95 
Add the correction * for the loss of weight of the 4I 
wires, by immersion 2^ inches deeper than >= ,oB 
when the counterpoise was adjusted 
And the true corrected weight of the cube in water, | 
with 6 o °,2 of heat, becomes - - j7 0 3? 0 3 
* When the cube was immersed, the water in the glass jar stood z\ inches higher 
than when the counterpoise for this water-scale was adjusted, and found to be 442,75 
grains; (see §. 18.) and 1 inch of alteration in the height of the water having appeared 
to be rz 0,0354 grain in weight, (§• 19 ) 2f inches will be = 0,078 grain ; and so much 
must be added, to correct for the loss of weight, in the four wires, that suspended the 
scale and cube in water. When the cube was immersed, the surface of the water 
stood 1,5 inch below the top of the glass jar, and 9,7 inch below the centre of the 
beam, or index point. 
When the cube was in the water, the beam was dearly^ensible yith of a grain.
