Harrison Allen also stated that in 1889 (Toner Lecture, Smithsonian 

 Institution) he announced the presence of a nodular hyperostosis on 

 the inner side of the horizontal ramus of the lower jaw of the Esqui- 

 maux. Virchow, 1890 (Zeitsch. fiir Anthropologic), briefly refers 

 to a sclerosed alveolar nodule in both the upper and lower jaw of a 

 Santa Barbara Indian. Dr. Allen thought it probable that Vir- 

 chow's claim (Crania Ethnica Americana, 1893) that his mass and 

 the one in the Esquimaux lower jaw were the same would not be sus- 

 tained. Virchow states that the Santa Barbara Indian exhibited the 

 nodules best developed in the upper jaw, which gave his observation 

 a distinct significance. Dr. Allen had lately noted the peculiarity, 

 previously observed by him in the Esquimaux, well-developed in the 

 lower jaw of the so-called Mound Builders. No claim is made that 

 the hyperostosis is of ethnic significance, though the presence of a 

 sclerosed hyperostosed surface constantly present in the Esquimaux 

 and occasionally present in the people of the Mounds, while it has 

 never been noted in the lower jaw of any other tribes, is an interest- 

 ing fact.
