ON THE ANTHROPOLOGICAL MBASDBEMENTS TAKEN AT BATH. 43^ 



2 per cent, was made by 4'1 per cent, of the males and by 10-2 per cent. 

 of the females ; and an error of 3 per cent, was made by 1-4 per cent, of 

 the former and 11 per cent, of the latter. 



The division of a line into thirds was done very equally by both sexes, 

 that is to say, the percentage of those who were correct and of those 

 whose error varied from 1 to 4-tenths of an inch was almost identical in 

 both males and females. 



The males were considerably better than the females in estimating a 

 right angle, 03 per cent, being correct, while only 337 per cent, of the 

 females were correct. The greatest error made by the males was 4°, 

 while one lady was 18" wrong, and nearly 8 per cent, had errors of 

 over 4°. 



A marked falling-off in accuracy of judgment, as before stated, took 

 place in estimating an angle of 60°, but it is only by using Mr. F. 

 Galton's method of projecting the statistics reduced to percentages that it 

 is possible to determine accurately whether the males or the females 

 examined had the more accurate ideas of this angle. At the 25th grade 

 the males show an error of 16°, while the female error at the same 

 grade is 2-2°. At the 50th grade the male error is 47°, the female 

 77° ; and at the 75th grade the error of the males is 9-5°, and of the 

 females 9-6°. From this it will be seen that the males Avere rather 

 more accurate than the females at this test, their percentage of error at 

 the 25th and 50th grades being lower than that of the opposite sex at 

 the same grades. 



The following tables show details of the statistics relating to the 

 judgment of the eye: —
