THE CHARTS 35 



N ? or F ? indicates that the individual has not been 

 definitely determined, but, considering all the data, it 

 is concluded that on the whole, the person was probably 

 normal or feeble-minded, as the letter signifies. 



A small d. followed by a numeral means died at 

 that age ; b. means born, usually followed by the date. 



A single figure below a symbol indicates that the sym- 

 bol stands for more than one individual the number 

 denoted by the figure, e.g. a circle with a "4" below it, 

 indicates that there were four girls in that fraternity, 

 represented by that one symbol. 



The Hand indicates the child that is in the Institu- 

 tion at Vineland, whose family history is the subject of 

 the chart. 



A black horizontal line under a symbol indicates that 

 that individual was in some public institution at state 

 expense. 



The fact that the parents were not married is indi- 

 cated either by the expression "unmarried" or by the 

 word "illegitimate," placed near the symbol for the 

 child.
