learned to walk. Of' table 1 c/, fam. 90 is a girl of 4 or 5 years, 

 having a somewhat deformed head on account of difficult partus. 



Let us now examine moreover, if the distinction with the brachy- 

 cephalic shape of the head can solve the contradiction of tlie data 

 of the tables IV and V. For this purpose we must consequently 

 consider the tables II to IV. It appears then, that in the families 

 of table II, where thus one of the parents and most of the children 

 have a high index, the parent with the high index has always a 

 large head. Only case 87<? (in an inferior degree case 179A) deviates 

 from this rule. In fam. 87^, the father whose mother's sister has a 

 short and small head {L 17.8, W 15.2, Incl. 85.3) renders perhaps 

 possible that among the children there are three short heads, (com- 

 pare below the explanation foi' family 3e). 



The tables III and IV contain the families of table V. In the 

 cases of table III the parent who has a high index, has 

 always a short, small head, none or only a single one of the indivi- 

 duals has here a high index. Fam. Ille is likewise interesting. Both 

 parents are brachycephalic and hav^e a short head. According to 

 what we stated before, there must consequently be many small and 

 short heads among the children. Of the twelve children the lengths 

 of the heads of the two eldest sons surpass those of the parents; 

 five childeren have very high indices and short heads, four others 

 are small brachycephalic, only three are mesocephalic, two of them 

 have a small narrow head (here we must take into account, that 

 most of the children are still young). These data confirm thus 

 tolerably well, that the short, small head is recessive, if it is 

 admitted in this respect, that there are some factors for the length 

 and some for the width, that the factors for greater length, resp. 

 greater width are more or less dominant over those for inferior 

 length and inferior width, whilst there is coupling between the 

 factors for length and width. Of the Fam. 113 both parents have 

 short heads and high indices, both children are brachycephalic (84 

 and 89 and shortheaded). 



Of the families of table IV mentioned likewise on table V 

 the brachycephaly of one of the parents relates to a rather 

 large and broad head. In the first case, family XI, the dolichoce- 

 phaly of the mother is however connected with a small, narrow 

 head. In the cases of table II the dolichocephalic parent has always 

 a large head. The little dimensions of the head, especially the little 

 width can in my opinion explain the comparatively low values 

 of the indices of the children. This holds perhaps likewise for fam. 

 147 and fam. 130. Here the father is likewise brachycephalic and
