age. This Table presents the conjugal condition of the parties ; 

 |ths of the weddings belong to BS ; 



2B : SV : 2M : : -866792 : -133209 : 100 : : 13 : 2 : 15, 

 and 



SS : SR : SF : : -910182 : -089819 : 100 : : 10 : 1 : 11. 



Likewise 22V = 32R nearly. The reciprocals of these numbers 

 to 100000 are also given. 



The sixth Report (p. 598, in 8vo) gave me the values of N,„, Ny 

 from 15 upwards, as the i dying before this age may be deemed 

 lost to humanity in our inquiry : which population in quinquiaval 

 sums, and the total mai-ried in the quiiiquennial -period 1851-55, 

 are shown in Table II. The quarto Report, p. 310-12, leads to 

 the fact that at 8-14614 years (p. 297), 2N„, = 2Ny= 1758661. 

 Table III. gives the various ratios of Table II., and Table IV. 

 the data reduced to the uniform base of 1000000, as also N,„-HNy 

 at each age; the numbers of Table IV. indicate that the nume- 

 rical 'Nuptial Law' is very difterent to that of the mortality law ; 

 and that at 53 years N,„ = N/. 



Table V. exhibits the quotients of SB, 2M by N™, and of 

 2S, SF by Ny, giving the numerical exponent of the desire for 

 matrimony. Thus of two equal sets of living men, the first set. 

 20-25, and the other set. 55-59, those who marry are as 

 429625 : 12234 : : 35 : 1 ; if these bridegrooms are all bachelors, 

 as 491485 : 1406 : : 350 : 1. Of two corresponding sets of 

 women, the ratios are 467425 : 5348 : : 87 : 1 and 508516 : 982 

 : : 518 : 1. With this is presented a summary of Table IV., 

 showing how many of a million of reproductive persons above 

 15 are younger than 20, 40, 50 and 55, N„, and N/ being -ith, 

 a half, |ths, f rds, and fths respectively ; and this is followed 

 by a specimen of the individual result for B20, S20 of the prin- 

 cipal toil in this reseai'ch. 



I calculated to the common base of 100000 the values for 

 each class and each life-limit, and to the base of 1000 the similar 

 values of each vertical and horizontal cohmin of the tabular Re- 

 ports. Table VI. gives the annual values of B, S in B S, &c., 

 the sum being 100000 : also the double of the quinquennial 

 sum or ratios to the base of a million : and the equiseval ratios 

 B : S, &c. 



Table VII. gives under each class the double quinquennial 

 sum (total a million), being the general table of the reports, 

 instead of 46134, &c. for bases ; the sum of the vei'tical columns 

 are the B, V of Table VI., and the horizontal sums are found in 

 the S, R of that Table. Zero shows where the value was below 

 a unit. 



Table VIII. shows how women of the same age are selected
