Therefore the differences of b , c , d , e , f g , and h , of the 
feveral fucceffive orders, are as follows : 
Firft differences. 
b - c is = .001,685,014,492; 
c - d = .001,464,124,410; 
d-e =.001,283,992,711; 
e-f =.001,135,173,816; 
f-g =.001,010,808,277; 
g - h =.000,905,817,276. 
Third differences. 
.000,040,758,383; 
.000,031,312,804; 
.000,024,453,356; 
.000,019,374,538. 
Fifth differences. 
.000,002,586,131 ; 
.000,001,780,630. 
Second differences. 
.000,220,890,082; 
.000,180,131,699; 
.000,148,818,895; 
.000,124,365,539; 
.000,104,991,001. 
Fourth differences. 
.000,009,445,579; 
.000,006,859,448 ; 
.000,005,078,818. 
Sixth differences. 
.000,000,805,501. 
Therefore d 1 is = .001,685,014,492; 
n 11 = .000,220,890,082; 
n m =.000,040,758,383; 
n IV =.000,009,445,579; 
D v =.000,002,586,131; 
D VI = .000,000,805,501.
