Nunn, E. On the Development of the Enamel of the Teeth of Verto- 
bratos. P. It. Soc. xxxiv. p. 156. 
The following aro the author’s conclusions : — “ (1) Tho cuticula dontis 
is formed by tho metamorphosis of the enamel colls, which have nothing 
whatever to do directly with the formation of the enamel. (2) The base- 
ment membrane may be demonstrated upon the surface of the tooth 
papilla and upon the tooth in all stages of development ; it becomes 
calcified with the other hard tissue of the tooth, and cannot be separated 
by acid. (3) The enamel, like the dentine, owes it origin to the odonto- 
blasts, the processes of which, in an early stage, may be traced quite up 
to its outor edge.” Several drawings of microscopic preparations are 
appended.
