FAMILY EECORD. 39 



194.5 9 L. E. A. (b. Apr. 29, 1866) emigrated to Oregon and 

 married the unrelated driver E. She has 6 children, 1945.1-1945.6 

 (p. 42). In a letter she states that her own hands are normal, but that 

 one of her sons has shortened index fingers. Her description of his 

 hands is, however, very confused and it is only with great reservation 

 we may assume that she is heterozygous for brachyphalangy while we 

 lack a more exact description and photographs of her hands and those 

 of her son. 



194.6 9 V. H. A. (b. May 18, 1868) Christiania, Norway. We have 

 examined this individxial and found that her hands are normal. She 

 married the normal L. and has a son. We have not examined his 

 hands, but his relatives state that they are normal, which was to be 

 expected. 



194.7 9 S. A., Christiania, Norway. Photographs of her hands 

 are given in fig. 21 and fig. 22. The III and IV fingers on one hand 

 were injured by an accident. Also in this case the hands when seen 

 from the dorsal surface would easily be regarded as normal. As seen 

 from the volar surface, however, the second phalanges of the indices 

 are markedly shortened, judging from the distance between the second 

 and third grooves. 



The radiographs (fig. 48) prove definitely the brachyphalangous 

 condition, the lengths of II 2 and IV 2 being 18 and 28 mm. respect- 

 ively on both hands. Like both her older brothers, she has the B-type 

 of brachyphalangy. 



She married Aa. and has a daughter, 1947.1 (p. 43). 



194.8 cf H. 0. (b. Feb. 15, 1874), Christiania, Norway. Seen from 

 the dorsal surface the hands of this man look as if they were normal 

 (fig. 23). From the inside, however (fig. 24), the second phalanges of 

 the indices seem to be slightly shortened, because the distance between 

 the second and third grooves, compared with the corresponding distance 

 on the fourth finger, is shorter than is the case in a normal hand. 



On the other side, the radiographs (fig. 49) give measures of the 

 phalanges which fall within the limits of variation in normal hands 

 based on the material collected by Pfitzner. The lengths of II 2 and 

 rV 2 are 22 and 27 mm. respectively on both hands. A radiograph 

 from the right foot (fig. 50) shows, however, a marked shortening of 

 the second phalanx of the second toe. This fact taken together with 

 the appearance of the volar smtface of the indices and the information 

 the man gives spontaneously that he uses the third finger instead of the 

 second in all sorts of finer work, indicates that he is really brachy- 

 phalangous. He states that when he- unties a knot he always uses 

 the third finger, as he also does when he picks up a needle from the 

 floor and in doing similar delicate operations with his fingers. We 

 accordingly interpret this case as an instance of the B-type of bra- 

 chyphalangy, corresponding to that of 1151.2 9 (p. 33). This man 

 is not married and therefore the genetic proof can not be obtained, as 

 it could in the other case just mentioned.
