290 HEREDITY AND SELECTION IN SOCIOLOGY 



of the pathological results which may be a consequence of 

 syphilis. As may be seen from the list enumerated by Professor 

 Fournier, almost every organ of the body may be affected.'- 



Natuke op the Eesults of Syphilis. 



Number of Cases 



observed 

 (Total of 4,400). 



Tertiary syphilis (cutaneous outbreaks) . . . . . . 1,451 



I Cerebral syphilis . . . . . . . . 758 



Locomotor ataxy . . . . . . . . 631 



Cerebro-spinal ataxy . . . . . . 45 



General progressive paralysis . . . . 83 



Syphilis of the spine . . . . . . 135 



Tertiary lesions of the reproductive organs . . . . 271 



„ „ of the tongue . . . . . . . . 262 



„ „ of the palate and roof of the mouth . . 215

Syphilis of the bones . . . . . . . . . . 519 



Lesions of the testicles . . . . . . . . . . 245 



„ of the eye . . . . . . . . . . . . 110 



Not to make this list longer, we have selected only the most 

 numerous results of syphilis ; the list, however, includes the 

 larjntix, the lungs, the heart, the aorta and the arteries, the 

 liver, the kidneys, the ear, the throat, the alimentary canal, etc. 

 And a single glance at the above figures suffices to convince us 

 of their gravity. Out of a total of 4,400 cases, there are no 

 fewer than 758 of affection of the brain ; and if we were to add 

 all the cases of affection of different parts of the nervous system 

 together, we should arrive at the formidable total of 1,652. The 

 consequences of these syphilitic lesions of the brain and the 

 nervous system are incalculably serious ; motor troubles, such as 

 hemiplegia, intellectual degeneracy, death, these are the most 

 frequent consequences. As Professor Fournier remarks : " Le 

 systeme nerveux est la victime preferee du tertiarisme . . . le prin- 

 cipe de la syphilis, s'il constitue un poison de tout I'etre, constitue 

 surtout et principalement un poison du systeme nerveux." 



And what are the results of cerebral syphilis ? Professor
