rods, laminated, crushed and rolled membranes, shapes 

 resembling slates, book-covers and shells, to the smallest 

 forms which possess a certain resemblance to various forms 

 of bacteria. 



The greater the number of bodies brought to view the 

 greater variety of forms is observed, while the methods 

 which stain only a limited portion of them select 

 special forms. Thus we sometimes find only small flat 

 or rod-like bodies, ur larger shell-like and hollow cylin- 

 drical bodies, which line the nerve channels in a narrow 

 layer without coming in direct contact with the nervse 

 at any ^joint. If we stain a series of spinal-cord sections 

 by various methods, it will be possible to bring out 

 certain bodies in every section, differing in form and 

 color, but similar in the four following respects, and 

 therefore plainly related to one another: 1, in their par- 

 aneural position; 2, in their athnity for methylene-blue; 

 3, in their homogeneous structure; 4, in their form, trace- 

 able to the fundamental plan of a shell-like structure. 



From these different pictures, brought out by different 

 staining methods on similarly prepared alcoholic sections 

 we must not conclude that we are dealing with artificial 

 products, but with masses of different chemical composi- 

 tion, whose individual constituents are made visible to a 

 varied extent and degree by different staining methods.

The Bath Waters. 



At a recent meeting of the Bath Microscopical Society, 

 Mr. J. W. Morris, F. L. 8., read an extremely interest- 

 ing paper on " Hazel Nuts and their Crystallised Con- 

 tents found in the course of Excavations at the Roman 

 Baths." 



Mr, Morris explained that the subject which he had
