sometimes produced the illusion of hemispherical dots. 
Mr, Hennau, enquiring whether any gentleman had any special 
object to exhibit, said he had brought down a number of slides, pre- 
pared by Dr. Addison, to illustrate the absorption vessels in the leaves 
of plants, referred to by Herbert Spencer in the Linnean Society’s 
transactions, and 18 slides of vegetable hairs prepared from specimens 
supplied to him by Mr, D’Alquen. 
Mr. C. P. Smitx had brought slides to show the difference be- 
tween the moniliform form of the gonidiac layers found in some algae 
as well as lichens. 
Mr. Wonror was prepared to illustrate fibro-cellular tissue and 
vegetable scales and hairs, and called attention to a method of pre- 
paring coal sections, described in the last number of the Quekett Club 
Journal, 
The meeting then became a Conversazione, when, in addition to 
the objects described above, 
Mr. GLAIsyeR exhibited saphides in American aloe and cuticle of 
pea, and potato starch in situ. 
Mr. R. Guatsyer exhibited fern scales and sections of coal 
showing woody tissues. 
Mr. HENNAH also showed a ready way of making a cell for dry 
objects with a brass ring and electric cement. 
A brass ring was held by a pair of forceps in the flame of a spirit 
Jamp until hot: then worked into a piece of electric cement, until 
covered with a moderate amount of the cement. It was now placed on 
a glass slide and held over a spirit lamp, and then put on one side to 
get cool. The object being arranged in the cell, and a thin glass cover 
warmed and laid on, the slide was ready for the cabinet.
