A SWEDISH FARMER'S LINEAGE 



67 



the »very defective* I comprise persons afflicted with idiocy, imbecility, mental 

 diseases, marked psychopathy, epilepsy, and myoklonus epilepsy, which is a 

 characteristic of this family. 



Table 4 contains in column E the whole material, and we find there, that 

 only 92 known cases of tubercolosis appears in the family, which is a small 

 number, even if this is stated as a minimum. It is surprising that such is the 

 case, in a family which in other ways is so defective. The reason of this is 

 probably, that the family in question is immune, to a great extent, to this disease, 

 usually so prevalent amongst the people. 



Several other farmer's families in the same district, are not in this way so 

 fortunately situated, for amongst them, mortality from consumption is much 

 greater than in the Lister family, in spite of the fact, that practically speaking, 

 they live under the same conditions. 



If we examine table 4 further, we find there that the number of cripples is 

 rather small (16), and suicide is rare (6 cases). Persons with psychical defects 

 are, on the other hand remarkably numerous (9.54 % of the whole number). 

 Weak intelligence is a very prominent defect.
