third half-year the relationship is reversed, and the foreign- 

 born actually exceed the natives in stature by a difference of 

 .36 inch. In the fourth half-year the superiority of the native- 

 born is regained, the difference in their favor being .42 inch. 

 For the two years as a whole, native-born Italian boys are . 1 1 

 inch^shorter than the foreign-born. Among Italian girls, the 

 native-born are taller only in the first half-year, by the narrow 

 margin of .08 inch. During the remaining three age-periods 

 the foreign-born girls have the advantage, with differences of 

 .12, .09 and .07 inch, respectively. For the two years as a 

 whole, native-born Italian girls are .06 inch shorter than the 

 foreign-born. 



The phenomena of weight among native and foreign born 

 Italian children are quite different, however, from those of 

 height. Among boys, natives show an excess of weight during 

 the first two half-years with differences of 3.52 and 2.70 pounds. 

 During the third and fourth half-years, on the other hand, the 

 foreign-born are heavier, first by only .01 pound, then by 1.40 

 pounds. For the two years as a whole, native-born Italian 

 boys are 1.45 pounds heavier than the foreign-born. Among 

 Italian girls, on the other hand, the foreign-born are heavier 

 only in the second age group, with a difference of 1.10 pounds. 

 In the first, third and fourth half-years the native Italian 

 girls have the advantage, with 1.80, 1.36 and 4.23 pounds, 

 respectively. For the two years as a whole, native-born 

 Italian girls are 1.02 pounds heavier than the foreign-born. 



Professor Boas in his volume " Changes in Bodily Form of 

 Descendants of Immigrants" gives similar data on the heights 

 and weights of native and foreign born Jewish and Italian 

 children, and it is of interest to compare our results with the 

 figures in his investigation. To make the two sets of figures 

 comparable, we have reduced ours from a half yearly to a yearly- 

 basis, and have grouped together the Boas figures for Sicil- 

 ians and Neapolitans, which are given separately in his tables, 

 to obtain the average for the Italians, The results are given 

 in Table 15 :
