As regards the a<j^e, we rejected all juveniles, and tlnis deleted 

 some 40 measurements. 'J-Jiose wliieli we have letained are, there- 

 fore, all adults, and the a<;es r\in from 2(» to 72, with a true mean 

 of 37.90. 



Concerning the nature of the crimes, our oljservat iotial data com- 

 prise such crimes as murih-r, iiianshmghtcr, wounding and assaidt, 

 sexual offences, larceny, embezzlement, forgery, house and shop 

 breaking, cattle stealing, inebriety, wife desertion, obscene lan- 

 guage, debt, receiving, false pretences, gambling, vagrancy. maii\- 

 tenance, suspected person, bigamy, impersonation and arson. 



As the numbers herein dealt with are very unequally distril)Uied 

 amongst the foregoing crimes, we have thought it desirable to 

 classify them into groups for convenience of working, and Ave thus 

 reduce the above many crimes to ten divisions, which, with the 

 number of criminals in each, aie as follow : — 



1. Murder and nianshmghter - - - - 11 



2. Wounding and assault ----- 15 



3. Sexual oflfences _...-- 56 



4. Larceny -------- 144 



5. Embezzlement .----. 5 



6. Forgery .._.... 14 



7. House and shopbreaking - - - - 26 



8. Cattle stealing --_-.- 6 



9. Inebriety -..----26 

 10. Miscellaneous 52 



Total - - - - 355 



Of the craniometric data we have recorded the maximum length 

 of the head, the maximum breadth, the auriculo-bregmatic height, 

 the maximum circumference, and the transverse arc. As all these 

 measurements were taken in accordance with the instructions issued 

 by the British Association Committee of Anthropometric Investiga- 

 tion in the British Isles, they require no further comment here. 



From the information furnished by the first three measurements 

 we have worked out the estimated cubic capacity of brain of these 

 355 criminals, as also the cephalic index, btit we have made no use 

 whatsoever of the circumferential measurements. They are simply 

 recorded and published for the information and use of any other 

 investigators who may care to avail themselves of the data. 



The details for the whole series under l)oth the personal and 

 craniometric heads are set forth in the tabic which accompanies 

 this work. 



Concerning the method by means of whicli tlie cul)ic capacity of 

 brain has been estimated from the three diametial measurements, we
