found to be lefs than the number of females. The rei- 
foil isj without doubt, that males are more diort- lived 
than females ; and this is owing partly to the peculiar 
hazards to which males are fubjed:, and their more irre- 
gular modes of life ; but it is owing principally to fome 
particular delicacy in the male conftitution, which ren- 
ders it lefs durable: for there are many obfervations 
which prove, that the greater mortality of males takes 
place chiefly in the firft and laft ftages of life. A few 
fa6ls of this kind I will beg leave to mention, becaufe I 
have juft met with them. 
In the parifli of St. Sulpice, at Paris, during 30 years, 
5 males under a year old died to 4 females. But under 
10 , only 13 males died to 12 females (fee susmilch.

In Stockholm, during 9 years ending in 1763, the 
number of ftill-borns amounted to 666; of whom 390 
were males, and 276 females; that is, 10 to 7. The 
number of the living in the town above the age of 80 
was, in 1760, 332; of whom 248 were females, and 
84 males, or near 3 to i. In the whole kingdom of 
Sweden, including all town and country inhabitants, the 
number of ftill-borns, during the 9 years juft mentioned, 
was 19845; of whom 1 1 424 were males, and 8421 
females, or near 4 to 3. The number of the living in the 
whole kingdom conflfted of more females than males, in 
' the proportion of 10 to 9. It conflfted of more females 
turned of 80 than males, in the proportion of 33 to 19;
