QUEKETT MiCKOSCOPICAL ClUB. 



Ordinary Meeting, October 22, 1875.— Dr. Matthews, F.E.M.S., 

 President, in tlie chair. 



A communication from Mr. E. Gardner was read, suggesting the 

 use of gum water (to which a little syrup of loaf sugar was added to 

 prevent cracking) in mounting Ostracoda and similar organisms. 

 Cells could be filled with this substance, and afterwards surrounded 

 with gum dammar, and so pennanently jjreserved. 



The President stated that it was intended to obtain an album for 

 containing the photographs of members ; which he requested might be 

 sent for that purpose. 



Mr. Bolton, of Stourbridge, exhibited the new rotifer, Melicerta 

 tyro, and communicated some particulars respecting it. 



Mr. B. T. Lowne gave an address " On some Recent Views of the 

 Classification of the Lower Animals," with particular reference to the 

 use of the terms Protozoa and Metazoa. 



Ordinary Meeting, November 25, 1875.— Dr. Matthews, F.R.M.S., 

 President, in the chair. 



The President announced that three albums had been presented to 

 the club — a large one by Mr. F. W. Gay, and two smaller ones by 

 Mr. J. W. Goodinge, and he requested that members would forward 

 their photographs for insertion in them. 



Mr. R. T. Lewis described some specimens of the Edelweiss, a 

 rare and beautiful Alpine flower, which he had mounted for the 

 cabinet of the club. 



Mr. B. T. Lowne gave an interesting accoimt of the various re- 

 searches which had been made by Mr. Darwin and others into the 

 nature of Insectivorous plants. 



Mr. T. Charters White read a paper, in which he treated of the 

 various structures likely to be seen in an ordinary section of a tooth 

 by the general observer. After alluding to a short paper he read 

 before the club four years ago on the Dental Pulp, in which he 

 described the dentine-forming organs or Odontoblasts, and a remem- 

 brance of which would help them in understanding the histological 

 construction of the principal portion, he proceeded to describe the 

 process of development in the enamel, the dentine, and cementum. 



The teeth may be regarded as dermal appendages, proofs of which 

 fact may be seen in the teeth studding the rostrum of the saw-fish 

 {Pristis antiquorum), or in the spear of the narwhal, at other times 

 occupying the interior of the alimentary canal, as in the Crustacea, and 

 being periodically shed with the shells of these creatures, while in 

 the human subject they occupy an intermediate position in this range, 

 and are placed only a few inches from the external surface of the 

 body, but partaking lai-gely of the character of the dermal structures. 

 'I' he author did not promise the members that he could furnish them 

 with any new facts as the result of original work, but would fairly 

 represent the views of such workers in this department of histology as 

 Sharpey, Tomes, Kolliker, and Strieker, and referred those interested 

 in his subject to the works written by these gentlemen. He then pro-
