Weight of Man at different Ages, 339 



'^< -A SCALE OP THE DEVELOPMENT OP STATURE AND WEIGHT. 



Children lose weight during the three first days after their 

 birth ; at the age of a week they begin sensibly to increase ; 

 after one year, they have tripled their weight ; — then they re- 

 quire six years to double the weight of one year, and thirteen 

 to quadruple it. 



To calculate the burden of an edifice, or a bridge, covered 

 with a crowd, it is well to know, that the mean weight of an in- 

 dividual, whatever is the age or sex, is about 98.584956 lb., 

 that is, 103.65756 lb. Avoird. for the males, and 93.7328 lb. 

 Avoird. for the females. 



During the development of individuals of both sexes, we may 

 regard the squares of the numbers representing the weights, at 

 the different ages, as proportional to the fifth powers of the sta- 



• Here the meter = 3.2809 imperial feet, which was used in the reduction, 

 and 2.20548 was used in weight, which is slightly greater than 2.20486, is pre- 

 ferred, though the difference is not worth minding.-.(?a/^atVA.
