REPORT— 1879. 



Speaking of the enamel of the molars of the mammoth, Professor 

 Leith Adams says, ' It is remarkably attenuated in teeth from the Arctic 

 regions' (p. 79), and that 'all the teeth [of mammoth] from Kent'3 

 Cavern, Devonshire, show the Arctic type and have thin enamel ' (p. 80). 



Again, he remarks, ' The Arctic or typical crown represented by the 

 North- Asiatic and North-American specimens on the one hand, and Kent's 

 Cavern on the other, presents a decided contrast to the molars from Iii< 

 on the Thames, where not only is the enamel thicker, but the teeth them- 

 selves are all much smaller. The same character [as to size] obtained in 

 other parts of the skeleton ' (p. 81). 



The author describes the specimen belonging to the ' find ' No. 1.063, 

 figured in his pi. ix., figs. 3, '3a, 36, 3c, as ' an excellent representative ' 

 of the antepenultimate or second milk-molar ' of the upper jaw, and pro- 

 bably of the right side.' ' The tips of the digitations of the four antnior 

 plates being slightly detrited show,' he says, ' the owner to have been, at 

 all events, not uterine ' (p. 85). 



Attention was directed in the Eighth Report (1872) to the specimen 

 No. 37-74 in the foregoing Table. Mr. G. Busk, F.R.S., a member of the 

 Committee, said then, ' I consider that it represents the very rare occur- 

 rence of a true mm. 1. . . . This is a very curious specimen, and, as 

 regards the elephant, of remarkable interest ' (Report, British Associa- 

 tion, 1872, p. 37). Professor L. Adams adopts Mr. Busk's determim- 

 tion, and adds, ' This tooth is one of the smallest milk-molars of any 

 elephant with which I am acquainted, and is even more diminutive th-.m 

 the first milk-teeth of the Maltese pigmy elephants. . . . The tips of one 

 of the digitations show signs of detrition, and the well-formed and con- 

 solidated fangs give evidence, at all events, that the aoimal did not die in 

 the womb. The probability is, therefore, that this very small tooth may 

 be a rare instance of the ^jre-antepenultimate appearing in the lower jaw 

 of the mammoth, its long divergent fangs leading to the belief that it 

 belonged to the mandible ' (p. 84).
