placed in his hands, to be presented to the Club, b7 Dr. Lattey, of Hastings. 

 As they were mounted in fluid, he thought it best to place them on one side for 

 some little time, to see how they would stand— and now finding, them quite 

 right, he had brought them to the meeting for presentation. The objects them- 

 selves were, perhaps, no great novelty, but the way in which they had been pre- 

 pared showed some very interesting features which were not to be met in the 

 ordinary bought slides and he had, therefore, asked Dr. Lattey to furnish a few 

 notes in description of them. Mr. Curties then proceeded to read Dr. Lattey's 

 paper, and on its conclusion intimated that the specimens alluded to were 

 being exhibited in the room under his own microscope and that of Mr. Brown. 



The President said he felt sure that all present would cordially unite in pre- 

 senting a vote of thanks to Dr. Lattey for his present, and also for his descrip- 

 tive notes, as well as to Mr. Curties for bringing them and reading them to the 

 meeting. 



A vote of thanks was then carried. 



Mr. T. C. White read a paper " On the Microscopical Structure of the so- 

 called Nerve of a Tooth," illustrating the subject by a diagram, and by prepara- 

 tions exhibited under microscopes in the room. 



The President proposed a vote of thanks to Mr. White — which he was sure 

 would be unanimous — for his very interesting paper. The field which had been 

 opened up to them by Mr. White was a very extensive one, and would well repay 

 the efforts of those who felt disposed to make it their study. There were many 

 points in connection with it, which time had only permitted him to touch upon, 

 but which involved considerations of very great interest. He had also omitted 

 to mention that Mr. White had brought with him for exhihition a very 

 beautiful preparation — perhaps a better one than would be found to exist else- 

 where- showing the nerve and the tooth pulp in a remarkably beautiful manner. 

 He had himself never seen so fine a preparation of this object, and desired to 

 call especial attention to it, 



A Member inquired of Mr. White whether the substance of the tooth was, 

 during life, being constantly removed and replenished, as was the case with 

 many other tissues of the body ? 



Mr. White, in reply, said he did not think it was at all possible that it was so, 

 as he was not aware of any organisation in a perfectly formed tooth by which 

 this could be accomplished ; no doubt there was a permeation of fluid holding 

 lime in solution into the tubes of the dentine, by which new osseous matter 

 could be deposited, and an endosmotic action took place sometimes, whereby in 

 cases of jaundice the tubes absorbed yellow fluid, and, in death by strangula- 

 tion, a red fluid ; but he did not think it possible that a process of removal and 

 renewal could take place in a human tooth. 



The President said that with regard to the very pertinent question which had 

 just been asked, and so cautiously answered, he thought Mr. White might have 

 gone a little farther, for it was quite certain that the tissues of the tooth were 

 not absorbed, although this was not very easily proved in every tooth. The tusk 

 of the elephant would furnish an example. It was properly regarded as only a 

 modified tooth. It was quite certain that the tip and free part of the tusk could 

 not be removed and restored, owing to its great distance from the source 

 of nutriment, as well as the nature of its substance. It had sometimes been 

 found that a bullet had become imbedded at the root of the tusk, and had by 

 growth in the course of time been pushed forward, until it had come nearly to 

 the extremity. Had the tissue been removable, changes would have been ob-
