32 A NEW TYPE OF BRACHYPHALANGY IN MAN. 



In this family we have secured exact information concerning the 

 feet which proves that the brachyphalangy shows regular vertical 

 correspondence, the two feet being symmetrically affected in exactly 

 the same manner as the hands. 



Line 1, V Generation. 



The fifth generation of Une 1 includes 10 families, 3 of which descend 

 from the normal 11.4 9 L. A. H. H. (p. 26), 7 from the brachypha- 

 langous 11.5 cf C. A. B. H. (p. 26). 



First Family of V Generation. 



114.6 cf H. H. had, by his marriage with M. E. B.,2 children, 1146.1 

 and 1146.2. 



1146.1 9 G. H. (b. Sept. 22, 1883). She married bank treasurer 

 C. C. (b. May 8, 1852) and had 2 children, 11461.1-11461.2 (p. 36). 



1146.2 9 A. H. (b. Aug. 29, 1892). She married in 1917 secretary 

 T.M. No children. 



Second Family op V Generation. 



114.7 9 T. H. had, by her marriage with J. M. G. B., 8 children, 

 1147.1-1147.8. 



1147.1 cf A. H. H. B. (b. Mar. 20, 1882). Unmarried. 

 1147.2 d^ E. B. (b. Sept. 24, 1883). Unmarried. 



1147.3 cf R. B. (b. Jan. 9, 1885). Married in 1916 B. L. R. No 

 children. 



1147.4 9 K. L. B. (b. Dec. 30, 1886). She married in 1910 con- 

 sultant J. J. and has 2 children, 11474.1-11474.2 (p. 36). 



1147.5 9 V. B. (b. Oct. 28, 1889). Unmarried. 



1147.6 9 D. B. (b. July 19, 1891). Unmarried. 



1147.7 (f G. B. (b. Jan. 30, 1894). Photographs and radiographs of 

 his hands are obtained as a test. They show that his hands are normal 

 in every respect. Lengths of II 2 and IV 2 are respectively 23 and 27 

 mm. on both hands. 



1147.8 9 T. B. (b. Dec. 10, 1895). 



Third Family of V Generation. 



114.80? A. H. had, by his marriage with A. A. L., 2 children, 1148.1 

 and 1148.2. 



1148.1 9 B. H. (b. Mar. 12, 1901). 



1148.2 9 A. H. (b. Oct. 10, 1902). 



The result of our investigation and of all information concerning 

 these three families of the V generation, line 1, is to the effect that the 

 members without exception had normal hands. To make a control 

 test and to get material for our comparative measurements we secured 

 the radiographs of one individual, 1147.7 cf. This accords with the 

 expectation which was based on the fact that 11.4 9 L. A. H. H. was 

 genotypically free from the factor for brachyphalangy (cf. p. 26).
