 to resemble either one parent or the other and not 

 an average between the two. 



The results of crossing the linear and the lateral 

 types with their opposites are described by Stock- 

 ard (1921-22, p. 62) as follows: 



Again there are persons who do not properly fall into 

 either type, nor are they typical intermediates, or blends 

 of the two types. These individuals may possess well 

 marked fully expressed features of the linear type along 

 with typically developed lateral features. They may be 

 dolichocephalic with near-sighted eyes, wide palate arches, 

 and tenor voices. Combinations that are at once out of 

 harmony. Such individuals are almost invariably found to 

 be derived from parents of opposite types, and they are 

 very common among the offspring of race mixtures. 



Environmental influences may tend either to 

 emphasize or neutralize hereditary tendencies. 

 According to Stockard, Keith and others, a person 

 may inherit from his parents a highly active thy- 

 roid gland which under favorable conditions would 

 cause a high rate of metabolism and produce 

 features of the linear type. But owing to disease 

 or deficiency in iodine this person's thyroid may 

 be checked in its activity and he may to that 

 extent acquire lateral features. On the other hand, 



another person may tend to inherit a more sluggish
