has its own special developmental history. May not many 

 morbid growths and pathological changes in the tissues of higher 

 animals and plants be regarded as instances of reversion in the 

 particular tissues to a condition which was normal in their 

 earlier history ? In these the growth of the cells is, as in the 

 embryo, more rapid and less closely restrained by polarity, so 

 that the resulting masses are mostly without definite form. 



Eyebrows were generally absent in the Admiralty Islanders, 

 very probably shaved off; the natives made signs when offered 

 razors, that they used obsidian knives for shaving. 



I did not notice that the natives seen at Nares Anchorage 

 had excessively large front teeth. This fact was observed by 

 Miklucho Maclay. Figures are given by him of the teeth. 



The septum of the nose in all the adults is perforated, and 

 the lower margin of the perforation usually dragged down by 

 the suspension of ornaments, so that in a profile view of the 

 face the large aperture in the septum is looked through by the 



observer. 



Some of the natives, as at Humboldt Bay, have most remark- 

 ably long Jewish noses. About 1 in every 15 or 20 has such a 

 nose. I at first imagined that this form of nose was produced 

 to some extent by long action of excessively heavy nose orna- 

 ments, but I saw one youth of only 16 or 17 with such a nose 

 very fully developed, and I saw more than one woman with a 

 well-marked arched nose with dependent tip, and the women 

 appear to wear no nose ornaments. 



The lobes of the ears of all the men were enlarged, being 

 slit and dragged down into long loops by the weight of suspended 



ornaments. 



The women wear as their only clothes two bunches of grass, 

 one in front, the other behind. The men wear as their only 

 dress, excepting a white cowry shell, occasionally a narrow strip 

 of bark cloth about five feet long and six or eight inches in 

 breadth, which is almost white when new and clean. The cloth 

 is in the form of a long natural sac, open at both ends, being 

 evidently loosened from the cut limb of the tree from which it 

 is made by beating, and then drawn off entire. This cloth is 

 sometimes reddened by being rubbed with a red earth used by
