2g6 The Rev. F. J. H. Wollaston on the 
divisors for each degree, instead of the simple divisor of 1,23 
for the whole. By taking the tenth of the logarithm of 1,23, 
the uniform divisor appears to be 1,021 ; but to make the 
successive divisors increase at the lower temperatures, as 
Dr. Ure does, suppose them to be taken thus ; 
1,02059 
1,02068 
1 ,02077 
1,02086 
1,02095 
1,02105 
1,02114 
1,02123 
1,02132 
1,02141 
10,21000 
The mean of which is 1.021. 
The logarithms of these divisors, if their differences be 
equalized by a small change in the last figure, will stand 
thus: 88501 
88892 
89282 
8967s 
90069 
90454 
90844 
9i 2 34 
91625 
92105 
the sum of these logarithms being 0,902583,^16 logarithm of 
1,23 nearly.
