86 THE JUKES. 



Table XII. gives the percentages on nine items contained in 

 tables VI., VII., VIII., IX. and X., and to this is added a line for 

 house-of-refuge boys. In statistics percentages are treacherous 

 when the numbers on which they are computed are small, so that 

 this table is given without claiming for it any great degree of au- 

 thority, especially in the items of robbery and larceny from the 

 person. But it is proximately reliable, because the elements out of 

 which it is made were critically verified, because in the items of 

 orphanage, neglected childhood, habitual criminals, refuge boys, 

 criminal family, pauper stock, intemperate family, habitual drunk- 

 ards, and without trade, the percentages ranging from one-fourth to 

 three-fourths of the total enable an approximation to be made upon 

 a very small number, even 50 unselected cases being sufficient in 

 most of these items. 



Nervously disordered stock. — Under this title are included all 

 convicts who are or have been afflicted with insanity, epilepsy, 

 idiocy, chorea, paralysis or other nervous disorder, or who have any 

 blood relations who are or have been subject to any of these dis- 

 L_eases. The number tabulated is greatly under the actual facts, be- 

 cause so many are either orphan or abandoned children who know 

 nothing of their ancestry. Of the 233 prisoners examined, 49, or 

 23.03 per cent, belong to this stock, or nearly one in every four. 

 If we compare the crimes against property with those of impulse, 

 placing arson among that category as in table XL, we shall find 

 that of the former there are 16.75 P^^ cent of neurotic stock, while 

 of the latter there are 40.47 per cent. This close relationship be- 

 tween nervous disorders and crime runs parallel with the experience 

 of England, where " the ratio of insane to sane criminals is thirty- 

 four times as great as the ratio of lunatics to the whole population 

 of England ; or, if we take half the population to represent the 

 adults which supply the convict prisons, we shall have the criminal 

 lunatics in excess in the high proportion of seventeen to one."* 

 In burglary we get 18.75 P^'* ^^^^ ^"<^ i^ larceny (grand and petit) 

 we get a little under the average 15.47 per cent, while in robbery 

 none are found. These ratios are not quite reliable, because those
