HRDLICKA] PIIYSTOLOGICAL AND MEDICAL OBSERVATIONS 193 



17 albinos were children, S adults. All 17 were complete albinos, but 

 of slightly differing shades. There was found in the two tribes no 

 instance of partial albinism or vitiligo. 



The general ap]>earance of the albinos in both tribes was much 

 alike. Their phj^siognomy, irrespective of their slightly variant color, 

 differed from that of the other Indians. Their skin seemed to be of 

 ordinary texture, but more sensitive to exposure than in the full 

 colored. It was pink or white with a slight flush, and the exposed 

 parts usually showed a more or less pronounced sun discoloration, 

 much like the ordinary sunburn among the whites. On the body the 

 skin looked absolutely normal; on the face, neck, and hands, in the 

 adults, however, it was rather redundant and wrinkled, or in folds, 

 giving these parts in some cases myxedematous-like appearance. 

 The lips were in many somewhat irregidar, exfoliating, cracked, or sore. 



The hair ranged in color from that of the unbleached flax fiber 

 (pale yellowish) tlirough various shades of yellowish and brownish — 

 always with a slight golden luster — to medium brown. In no in- 

 stance was there any trace of red in the hair. The eyebrows and 

 eyelashes as a rule were lighter than the hair, in some cases practically 

 colorless. The consistency and quality of the hair showed no features 

 strikingly different from those found in ordinary Indians of the same 

 tribes. 



The eyes were light gray or light blue to moderate gray-blue, with 

 sclera white — very much like eyes of similar shades in blond white 

 people. In no case was the iris colorless, with pink reflection, as in the 

 albino rabbit. In ever}" instance there was a more or less marked 

 nystagnuis and heliophobia. The vision was not strong, but short- 

 sightedness was not noticed. 



Owing to the blinking eyes and the more or less abnormal skin, 

 the face was generally somewhat sheepish in expression, reminding 

 one of the faces of some epileptics. In most of the adults the nose 

 was thicker than the average, while in the majority of cases the lips 

 were thickened and, as already mentioned, somewhat irregular in 

 shape. These conditions are undoubtedly very largely the effects of 

 irritation by wind and sun. In four cases the teeth were somewhat 

 crowded or irregularly set. In one of the Zuni men half of the teeth 

 had been lost. In no case was there found any decided retardation 

 in dentition or any anomalies of the teeth. The palate was in all 

 fairly regular. 



Measurements of the body showed that neither the cliildren nor 

 the adults differ much from normal individuals of similar age and full 

 color. In no instance were there seen signs of scrofula, congenital 

 syphilis, or rachitis. The pulse, respiration, and temperature in two 

 of the albinos, who were in perfect health, aj3proached closely the 

 average of the tribe ; in other individuals these tests were interfered
