 Of the female murderesses tine. Martha Needle, is eix'dited bv the 

 corrected reading ■\vitli a surprisingly small amount of inain — 

 namely, 1121.5 c.e. 



In Table III. is established a direct comparison i)ctwi'cn the 

 English Pail^hurst ujurdcrci' and tlie Australian mui'di-rcr. Here 

 are al.so shown the uncorrected and corrected figures for both the 

 male and female Australian ci'iminals. f'oncenti'ating oui- atten- 

 tion solclv uiMiu the cori'ccted readings, the tal)lc cstai)lislK's the 

 tact that the English muidcrci- is a slightly moi-e intelligent ])erson 

 than is his Australian confrere, for the true mean of the former is 

 1491 ±10.25, as against the hitter's 1471.9^10.57. 



What, however, is m(n-e important than the slight difference of 

 the ti-ue mean in favour of the English criminal, is the fact that a 

 study of the standard deviations, as well as of the individual range 

 of variation shows cleai"ly that nnirder, as a crime, is not nearly 

 so restricted to one section of the conmiunity in England as in 

 Australia. Why this should be we have no jiieans of knowing, but 

 wc think the table clearly reveals that such is the case. 



In Table IV. we have instituted a comparison of the cidiic 

 cai»acity of brain of these English and Au.stralian murderers with 

 those several learned classes utiliseil by us in o\ir juevious com- 

 munication on this subject (1). The general result attained by this 

 table confirms the conclusions pi'eviously drawn—namely, that for 

 clas.ses there is an appreciable correlation between size of head and 

 intelligence. It will be seen that the three groups of crinnnals -Avr 

 at the bottom of the list altogether behind the true means of the 

 learned classes. The same geiK-ral conclusion also holds good for 

 the females where we have been enabled to institute a dii-ect com- 

 parison between three Melbourne murderes.ses and 'M) Bedford Col- 

 lege women students. For the latter figui-es we aie indebted to the 

 work of Miss Lee (2). from whose statistics we have ourselves cal- 

 culated the standard deviations and probable errors. The table 

 shows clearly that for the classes of both sexes the correlation be- 

 tween size of head and intelligemc would ai)i)ear to hold good. 



In Table V., the last of the series, we have instituted a com- 

 parison between the corrected cubic capacity of each individual 

 Melbourne murderer and the true means of the several learned 

 and criminal classes of our previous work (1). The list is headed 

 by six criminals, then follow two of the learned classes, two nuire 

 criminals, another of the learned classes, two more crinnnals, 

 and finally the last of the educated groups. Of the 27 

 individual Melbourne murderers herein dealt with, no less tlian
