Urn- a?Min we see that drink has practically no influence on the 

 general health and intelligence of boys and girls, and the little influence 

 it has is in favour of the children of drinking parents, they are healthier 

 and more intelligent. These results are certainly startling and rather 

 upset one's preconceived ideas, but it is perhaps a consolation that to 

 the obvious and visible miseries of the children arising from drink, 

 lowered intelligence and physique are not added. 



But before asserting that intemperance of the parents has prac- 

 tically no effect on the physique and intelligence of the children, there 

 is a point to be considered which we mentioned in the first part of this 

 paper. What is the status of the drinking workman? Is the drinker 

 on an average the abler man and of finer physique ? If so, his children 

 should show greater ability and better physique than the children of 

 the non-drinking parent, and further, if the abler workman get higher 

 wages, and thus notwithstanding drink, the food at home has been of 

 better quality, we should expect his children to be better developed 

 physically than those of the non-drinker. 



As before the only estimate we have at present of the intelligence 

 and physique of a workman is the wage he earns. A high wage on an 

 average will mean a stronger and more efficient workman. We want 

 to discover therefore whether drink and good wage go together to any 

 large extent. If they do, then drinking fathers should have stronger 

 and more intelligent children than non-drinking fathers. But unless 

 there is a fairly well marked correlation it will not be sufficient to 

 affect greatly our results. 



We divided parents into three classes: (i) both parents drink, 

 (2) one parent drinks, (3) neither parent drinks, and the wages into 

 four groups: (i) under i8s. a week, (2) i8s. 245. inclusive, (3) 265. 

 to 345., (4) 365. and over 365. The correlation coefficient found by 

 the fourfold method between the drinking of one or both parents and 

 a high wage is -03, which means that there is practically no connection 

 between drinking of the parents and a high wage. The means show 

 the same thing the mean wage when both parents drink is 245. 8d., 

 when one parent drinks is 255. 6d., and when neither parent drinks 

 is 255. $d. there is a slightly lower wage when both parents drink 

 and a very slightly higher when one parent drinks, but we cannot 

 attach any importance to a difference of id. We tried to find from
