172 THE PE0CEEDING8 OF THE LINNEAN SOCIETY 



During my second stay (1876-77) on the Maclay-Coast of New 

 Guhiea 1 found several individuals who had some teeth of abnor- 

 mal size, and which, like those on Taui and Agomes, presented 

 no pathological condition. I met three or four of such people 

 amongst the inhabitants of the archipelago of the " Content 

 men," also in some of the mountain villages of the Maclay-Coast. 

 In Zamhoanfja on the S.W. point of the Island Mindanao (in 

 Jany., 1878), I met a native (whose ancestors, as he informed 

 me, were Bugis) whose teeth of considerable size were very 

 remarkable. 



In 1878 I saw in Singapore a Chinese Coolie in the street, 

 whose large teeth were well shown by his hearty laugh, and 

 which attracted my attention. Owing to my illness I was pre- 

 vented from sketching or measuring this specimen. 



Amongst my older notes I found a memo, that in 1873, on the 

 Island Tidore, I saw a Malay with remarkably large teeth ; in 

 the same year (1873) I also saw a Chinese in Canton with very 

 large teeth. 



In conclusion, I will remark that the opinion which I 

 have formed (and which I have communicated in my second 

 report to the Imperial Geographical Society of Russia in 1876) 

 is that Macrodontism (or hypertrophy of the dentinum) should 

 rank in the same category as the elongation of the nymphse, 

 and the accumulation of fat about the buttocks and sacrum in 

 the Hottentot woman, and in a similar manner as this peculiarity 

 of constitution, Macrodontism is not to be met amongst all 

 individuals. 



That this Hypertrophy of the Dentinum stands in close rela- 

 tion with the food is without doubt ; but during my compara- 

 tively short stay in the islands I could not discover the particular 

 diet which causes this anomaly, or might have caused it, as it is 

 certain that the peculiarity is hereditary.
