Table XVI. — Table showing the Average Height and Weight at each 

 Age of Persons of all grades of Country Origin, of all grades of 

 Town Origin, and of all grades of Town and of Country Origin. 



Mem. — Comparing the two columns lieaded ' All Grades of Country Origin ' and 

 'All Grades of Town Origin,' it will be observed that those of country origin have 

 in nearly every case an advantage in height and weight over those of town origin ; 

 and on referring to the table at foot, where the results are given in periods of 

 three years, this will be still more noticeable. 



V. As to Growth. 



One very interesting branch of the inquii-y with which your Com- 

 mittee is charged is the annual development of young people of both 

 sexes ; but the opportunity of obtaining such information continued over 

 a considerable number of years is very rare, and the Committee have as 

 yet been able to procure only one return of this nature. It relates to the 

 yearly growth of a small number of children of American parents, pre- 

 sented by Dr. Bowditch, Professor of Physiology in Harvard Medical 

 School. But they are of opinion that the publication of it, and of some 

 results which have been deduced from it by the Committee, may be useful 

 in suggesting to persons who are in possession of similar observations, 

 however few in number, and limited in period of record, to communicate 

 them to the Committee. Many parents take the height of their children 

 periodically ; a few perhaps take their weight also. Ati examination of 

 Tables XVII. and XVIII., and the remarks thereon, will show to what 

 good account a collocation and comparison of such facts may be turned. 



Table XVII. is a comparative statement abstracted by Sir Rawson Raw- 

 son from Dr. Bowditch's original table, of which Table XVIII. is a copy.
