56 FAMILY STUDIES IN BUILD. 



Of the two children who grew up : 



1. Male, a civil engineer, has at 33 years the formula 180/68 inches; 

 build 2.7 (39) ; adjusted to 55 years, 189/68 inches; build 2.9 (41). 



2. Female, a student, has at 26 years the formula 150/69 inches - ; build 

 2.2 (32) ; adjusted to 55 years, 170/69 inches; build 2.5 (36). 



Comment. — The children exceed in build the stouter parent; probably a 

 result either of heterozygosis or multiple factors (R: Jos-1). 



Nob-1 Family. 



A family of English extraction; paternal grandparents living in Illinois 

 and Minnesota, maternal grandparents living in Canada and Minnesota, 

 parents and children living in Illinois and Minnesota. The Father, a livery- 

 man, a very energetic, nervous man, is in middle age liable to rheumatism. 

 He has at 47 years the formula 140/74 inches; build 1.8 (26). His father, 

 a farmer, who in middle age suffered from asthma, colds, and heart trouble, 

 died at 65 years from heart failure, having the formula M/M. His mother, 

 who had 11 children, suffered in middle age from bronchitis. She is living 

 at 77 years, having the formula M/M. 



The Mother, who has had 7 children, has the formula 105/66 inches; 

 build 1.7 (24). One of her brothers hung himself; one of her sisters was 

 always "sickly" and toward the end of her life "very peculiar." Their 

 father, a farmer, suffered in middle age from heart trouble. He died from 

 "dropsy of heart." At 60 years his formula was M/M. Their mother, who 

 had 7 children, is living, now insane. At 61 years her formula was M/M. 



The 7 children are: 



1. Female, a student, who in youth suffered from adenoids and tonsillitis, 

 has at 21 years the formula 110/65 inches; build 1.8 (26). 



2. Female, a bookkeeper, has at 19 years the formula 100/66 inches; 

 build 1.6 (23). 



3. Male, a student, has at 18 years the formula 112/67 inches; build 

 1.8 (25). 



Comment — There are four children below 18 years. Of these, No. 4, 

 at 14 years, is 18 pounds below standard; No. 5, at 12 years, 15 pounds 

 below; No. 6, at 8 years, 2 pounds below; and No. 7, at 5 years, 2 pounds 

 above standard. 



Thus the entire family, omitting the 5-year-old, is below the standard 

 and mostly very slender or slender. In view of the fact that the parents 

 are, at around 45 years, still slender or very slender, it is doubtful if the 

 children's weights should be adjusted; it is probably a family character- 

 istic not to put on weight in middle life. This family supports the view 

 that extreme slenderness is a recessive condition, or, at least, is determined 

 by prevailing recessive factors (R: Nob-1). 



Mating 4. Other Slender x Slender Matings (included in table 23). 



Since by hypothesis slender parents will rarely carry gametes with 

 more than 1 factor for fleshiness, it becomes important to consider 

 the remaining slender X slender matings, i. e., without special regard 

 to the grandparental conditions. A summary of the distribution of the 

 progeny of all slender X slender matings is given in Table VI (Ap- 

 pendix). This shows that of 51 grown children (resulting from 24 

 matings), 5 are very slender, 35 slender, and 11 of medium build.
