" On the Development of the Teeth of the Newt, Frog, Slowworra, 

 and Green Lizards." By Ciiaru;s S. Tomes, M.A. 



That the " papillary stage " of tooth-development could not be 

 said to exist at any time either in the frog or in certain fish, was 

 pointed out nearly twenty years ago by Professor Huxley, who, 

 however, accepted, on the authority of (ioodsir, the latter's theory 

 of the process as true of Man and MammaUa. In more recent 

 years Kulliker and AValdeyer have traced out the course of the 

 development of teeth n-ith great accuracy in Man and some other 

 Mammalia, with the result of shov^ing that the usually accepted 

 views propounded by Goodsir and Arnold are not by any means 

 an accurate representation of what takes place in them. 



Since the date of the publication of Professor Huxley's paper, 

 I am not aware that any thing has been published bearing upon 

 the development of the teeth of Reptilia and Batrachia, save a 

 paper by Dr. Lionel Beale upon the development of the teeth of 

 the Newt, and a short and iuconclusive paper by Santi Sirena ; 

 with the exception of the papers alluded to, the subject may be 

 taken to stand in the position which it occupied at the time of 

 the publication of Professor Owen's ' Odontography,' in which we 

 are told that the teeth-germs of Reptiles and iJatrachia never 

 stop at the papillary stage, but that the primitive dental papilla 

 sinks into the substance of the gum and becomes inclosed by a 

 capsule.
