This Table is what I fometimes make ufe of for finding the 
Logarithm of any Number propos’d, and vice versa. For in* 
fiance: Suppofe I had occafion to find the Logarithm of 20 do . 
1 look in the firfl Clafs of my Table (the whole Table confifts 
of 8 Clafies) for the next lefs to 2, which is 1.995261 3 15, and 
againfl it is 3, which confequently is the firfl Figure of the Lo* 
garithm fought. Again ; dividing the Number propos’d 2, by 
1.9952623 1 5 the Number found in the Table, the Quotient is 
H.002374467; which being look’d for in the fecond Clafs of 
the Table, and finding neither its equal, nor a lefier, I add o 
to the part of the Logarithm before found, and look for the 
faid Quotient 1.002374467 in the third Clafs, where the next 
lefs is 1.001305238, and againfl it is 1, to be added ro the 
part of the Logarithm already found ; and dividing the Quoti- 
ent 1.002374467, by 1.002305238, laft found in the Table, 
the Quotient is 1.0000690705 which being fought in the 
fourth Clafs gives o, but being fought in the fifth Clafs gives 2 , 
to be added to the part of the Logarithm already found ; and 
dividing the laft Quotient by the Number laft found in the Ta- 
ble, viz. 1.000046053, the Quotient is 1.000013015, which 
being fought in the fixth Clafs, gives 9 to the part of the Loga - 
rithm already found: And dividing the laft Quotient by the 
n ew Divifor, 'I'is. 1.000002072, the Quotient is 1 000000229, 
which being greater than i.cooocoi 15, fhews that the Loga- 
rithm already found, viz. 3.3010299 is lefs than the Truth by 
more
