influence. In general, it seems reasonable to admit that the diversity of occupa­ 
tion, journeys, feasts, periods of fasting and mourning, and the other civil and 
religious customs may have a notable influence on the greater or lesser fre­ 
quency of conceptions. The influence of religious customs appears clearly if 
we compare the birth-rates in the Protestant districts of Germany with those of 
the Catholic and mixed. (See Table VI.)

(x) The data for Roumania were worked out by the author from the original official statistics ; 
those for Germany are taken from Mayr, Statistik und Gesellschaftslehre. Page 172. 
We may, perhaps, ascribe the differences between town and country which 
in Roumania for example are considerable (see Table VI.) to the influence of 
the different professions. But it is probable that here, as certainly in other 
cases, the influence of the frequency of marriages according to months comes 
into play. 
I do not know upon what data the assertion is founded which is at present 
taken for granted by statisticians, that the monthly oscillations in the frequency 
of marriages have no sensible influence on the monthly oscillation in the 
frequency of births. The explanation of this fact should be found in the 
variation in the interval between marriage and first birth. 
However, it is clear that this variation may shew well marked differences 
from country to country according to the greater or less diffusion of Neo- 
Malthusian practices, the relative ages of those marrying, and especially, the 
greater or less frequency of conception before marriage. Owing to this, it may
