the offspring reaching adult age were affected. But these are probably 

 selected pedigrees, and are not numerous enough to draw definite conclusions 

 from. 



Group 2, in which there was an insane inheritance on one side only. 

 Ninety families were examined. Of 384 children born alive 40 died in 

 early life; there were 33 insane, suicide, or nervous disease, and 311 normal. 

 Thus 9-6% of the offspring reaching adult age were affected. 



The conclusion which possibly might be drawn is that a_ghilj horn r>f a 

 dual neuropathic inheritance^ stands on an average a chance of being insane 

 four H^ a^-great aVjySere only one stock is infected. This, however, 



applies to the mass and not the individual. 



It might be argued that there are a certain number of imbeciles who 

 could be allowed all social privileges excepting reproduction ; this would 

 be on the ground that they could pick up a living, and sterilization would in 

 no way interfere with their doing this. The objections are: The cry of 

 one law for the rich and another for the poor ; and the legalisation of an 

 operation that is fraught with many hidden social dangers. I often think 

 that a number of people who are crying out about the monetary burden of 

 supporting the unfit are themselves not doing their duty to the race. Many 

 have no children or they restrict the births ; moreover, one does not find the 

 numbers in a family increase with the income. When hereditary health as 

 shown by longevity, fertility, and mental stability in a stock is regarded as 

 a greater asset for happiness in the family and the nation than hereditary 

 wealth, then will be the time for the rich and comparatively prosperous to. 

 suggest the desirability of sterilization of the insane 'pauper. For no one 

 supposes that it would be carried out in all classes..
