I have tried to examine the criminal from the endocrine standpoint and will give an outline of statistial consideration by wry of the 1st report on the observation with regards to the testicle-size and criminal-quality in addition to the observation of the secondary sexual signs.
As the testicle-length-distance from up end to down end, the testicte-thickness-from back edge to front edge, the testicle-width-from right side to left side, when it is measured by the gleitzirkel of the “Martin's type” with an attention not to bring any pressure upon the testicle, keeping by hand the scrotum tense and fixed. Moreover, the inmates were divided into two classes according to the matured signs or the secondary sexual signs of the persons at the adolescense by the intuitive method.
1,505 healthy inmates of ages ranging from 16 to 65 were used as tire objective who were grouped according to the legal classification, with a special consideration of means, action, motive or cause, simpleness or habitualness, strong or weak will about their crimes and also the terms of penalty were referred to.
The matured-degree from the frequency distribution of the secondary sexual matured sign or the growing-degree of these persons of 16 to 25 years was shown by an expression. By that, it seemed to me that both the testicle-size and the growing-degree have a tendency of increasing little by little up to about 20 years of age and they showed an incomplete possitive correlation(korrelationskoefficient r=0.28)till some 26 years old, showed an incomplete negative correlation(r=-0.22)for persons from 39 to 50 years old, whose testicle-sizes decreased more or less as far as testicles and ages are concerned. The decline is smallest in the case of persons of 51 to 55 comparing with younger people, but the testicle-size increased and showed the adult-size in persons of 60 to 65 again.
The testicle-sizes obtained are as follows;
It is found that the testicle-size increase in order of each group of criminals of the fraud. the larceny, and the vicious offenders.
Of the vicious offenders, the quasi-robbers have the smallest testicles than the others (37.12×26.92×22.20mm 22.16cc) and the size of their terticles is almost the same of the fraud-offenders. On the contrary, the size of the testicles of the robbers made up of principal offendersa( 39.71×29.27×23.60mm 27.45cc) is the biggest among various criminals, and also the murder, rape, arson-offenders have relatively larger testicles. It is found that there seems to be material difference in the size of testicle between the the first offender and the habitual offender.
The exactness of the mean calculated according to M ± 3m showed the sphere of locomotion of 033-0.54 for the criminal-adults, with 0.56-0.78 for vicious offenders, 0.54-0.78 for the larceney-offenders. It can be regarded as a genuine arithmetic mean. The fraud offenders have moderate exactness with the sphere of 0.90-2.70 in the average for 5 diameters.
If one compares the mean by way of M1-M2/√m
21+m
22, there is a significance among the three groups as far as the length is concerned ; in the thickness, there is it between the vicious and fraud offenders, and between the fraud and larceny offenders and in the width there is it between the vicious and fraud offenders. There is also a significance between ages except certain ages.
Summarizing these results, I have found that there seems to be some meaning between the so-called “Masuline” and testicle-size, and also between the endocrine function and size of testicle.
