NURTURE AND NATURE

The next table gives the mean height and weight 

 for each class. 



Table III. 



We see then that men occupied in a trade with 

 a lower mortality rate are heavier and taller than 

 men in a trade with a higher mortality rate, which 

 suggests that the very small correlation we have found 

 between unhealthiness of the father's trade and the 

 height and weight of his sons is not all due to the 

 unhealthiness of the trade, but is due at least, in 

 part, to the inferior physique of the father. In fact 

 I have very little hesitation in saying that unhealthi- 

 ness of a trade of a father has small influence on the 

 physique of his sons, and that it is because men of 

 inferior physique are forced into worse trades that 

 we see this apparent slight connection. 



I will now turn to the question of drink and 

 measure its effect on the height, wefght, general 

 health and intelligence of the children. I suppose 

 more disastrous results have been attributed to drink 

 than to any other social evil — I might almost say 

 than to all other social evils taken together. Since 

 we have been working at this subject I have read 

 carefully many speeches, as reported in the papers, 

 on the subject of drink, and confess I have been 

 somewhat astonished at the statements occasionally 

 made.
