To make ufe of this table, in the left-hand perpen- 
dicular column look for the number of degrees con- 
tained in that part of the tube which is not immerfed in 
the fluid whofe heat is to be tried, and in the upper ho- 
rizontal line feek the fuppofed difference of heat of the 
quickfilver in that part of the tube from that in the ball ; 
the correfponding number in the table is the correction, 
which muft be added to the obferved heat when the 
5 N 2 quick-
