28 (220) SERIES OF INDICES OF WHICH. A SINGLE . 
tion according to the formula DR x RR the presence of the 2 micro- 
brachycephalic daughters is conveniently explained. 
Family 53b. The father is dolichocephalic, the mother very much 
brachycephalic; both parents have average large heads. Two sons are 
macrodolichocephalic. Two daughters are dolichocephalic with some- 
what smaller heads than average large. The 3rd daughter has the 
same index and headsize as the mother (table IX). 
Of the incomplete families is in family 59a the mother dolichoceph- 
alic with a rather large head. A daughter is dolichocephalic with a 
very large head. A daughter with a verysmallhead is brachycephalic. 
Family 97. Five brothers and sisters with small heads and diverging 
indices. The youngest sister is very much microbrachycephalic. 
Family 247. The father is microdolichocephalic. A son and a daught- 
er are macrodolichocephalic. A 2nd son is macrobrachycephalic, a 
2nd daughter is in a high grade microbrachycephalic. 
Family 301. Family 238. The mother ismacrobrachycephalic. Oneson 
is very much microbrachycephalic, a 2nd son is macrodolichocephalic. 
Family 190. The mother is macrodolichocephalic (79). The indices 
of the 7 children are: 77, 77, 78, 78, 79, 79, 81. This family might also 
have been taken up into table IV or table I. | 
Family 292. The mother is microdolichocephalic (78). Series of the 
indices of 5 children: 77, 78, 78, 80, 82, The youngest daughter has the 
index 82 and a somewhat smaller than average large head. | 
Family 14. The indices of 6 brothers. and sisters are 76, 78, 118,018; 
78, 80. The brother with the index 80 has a very large head. 
In these 13 families where the deviating high index belongs to a 
small head, in three cases both parents have small heads (27, 164, 18a), 
in 7 cases one of the parents has a small head the other one a large 
one. (222, 196, 1, 298, 224, 19a, 17) and in 3 cases both parents have 
large heads (268, 228a, 53b). As regards these last three cases, in family 
268 (p. 26.) the microbrachycephalic child is the youngest and a 
feeble girl; so it may be a non-hereditary modification. 1) In family 
228a both parents have moderately large heads; in family 536 of the 


*) As we did not inquire, whether patients of psychoses (dementia praecox, idioty, 
etc.) have a characteristical headform, it is not allowed in general, when finding in a 
series of children a deviating headform and this is of such a patient to accept that ill- 
ness as the cause of the deviation. However, in the cases, where we have mentioned 
with the deviating index personal particularities, it always regards bodily abnormal- 
ities, that can directly have influenced the index (ala long illness of the first years of 
life, rachitis, lues, general bodily backwardness and deformity).
