38 A NEW TYPE OF BRACK YPHALANGY IN MAN. 



representing the third family of the IV generation, line 9. We have 

 been able to examine several of these individuals and their descendants 

 of the V and VI generation. Only this part of the line 9 will here be 

 treated. 



The children of 19.4 9 L. E. 0. state that their mother had normal 

 fingers. That she, however, must have been heterozygous for the 

 factor for brachyphalangy is clear in view of the fact that several of 

 the children are brachyphalangous. We may accordingly safely con- 

 clude that she had the B-type of the malformation. 



LINE 9, IV GENERATION. 

 THIRD FAMILY OF IV GENERATION. 



This family comprises the 10 children of 19.4 9 L. E. 0. and her 

 unrelated husband, L. J. A., 194.1-194.10. To avoid confusion we may 

 mention that several of these individuals later changed their last name. 

 This is the reason why the last initial differs within the same family. 



194.1 9 C. F. A. (b. June 9, 1859) emigrated to Minnesota, where 

 she married farmer F. No children. 



Replying to inquiries concerning her fingers, she answers in a letter : 

 "Both my index fingers are a little shortened. The second phalanx is 

 shortened. Mother had not shortened fingers, but an uncle had like 

 mine." It is clear from this description that she has the B-type 

 brachyphalangy, a view that is confirmed by the entirely different 

 way in which she described the index fingers of her niece, 1942.1 9 

 J. G., who has the B !-type brachyphalangy (p. 40). 



194.2 d* A. K. A. G. (b. Sept. 22, 1860) manager of a restaurant, 

 Bergen, Norway. The photographs (figs. 19, 20) and radiographs 

 (fig. 46) of his hands represent a typical case of the B-type of brachy- 

 phalangy and need no further description. The lengths of II 2 and 

 IV 2 are 17 and 26 mm. respectively on both hands. Aside from the 

 second phalanges of the indices, the other bones of the hand are normal. 

 This man married twice. By his first marriage he has a daughter 

 1942.1 9 . By his second marriage with the normal, unrelated 

 A. E. M. (b. Jan. 30, 1880), he has 4 children 1942.2-1942.5 (pp. 40-41). 



194.3 cf E. A. L. (b. Sept. 3, 1862), manager, Bergen, Norway. 

 Photographs of his hands are given in figs. 21, 22. Seen from the dorsal 

 side they could easily be regarded as normal. The photograph of the 

 volar surface, however, in connection with the radiograph (fig. 47), 

 reveals a clear case of B-type brachyphalangy. The lengths of II 2 

 and IV 2 are 22 and 30 mm. respectively on both hands. 



E. A. L. married the normal, unrelated A. M. S. (b. Aug. 9, 1865) 

 and has 5 children, 1943.1-1943.5 (pp. 41-42). 



194.4 9 K. 0. A. (Sept. 25, 1864-1914). Emigrated to Alaska, where 

 she married the unrelated J. O. and had 4 children, 1944.1-1944.4. 

 No information concerning her own or her children's hands has been 

 available.
