PROCEEDINGS OF SOCIETIES. 

Microscoricat Socinty, March 30th, 1859. 
Dr. Lanxester, President, in the chair. 
F. E. Webb, Esq., J. O. Dix, Esq., and Joseph Beck, Esq., 
were balloted for, and duly elected members of the Society. 
Dr. Bowerbank read a paper on Grantia ciliata (‘ Trans., 
p- 79). 
A paper by Mr. Edwards, ‘On Diatomacez,’ was read 
by Mr. Roper (‘ Trans.,’ p. 84). 
It was resolved, “That the microscope-makers who adopt 
the standard screw be requested to ascertain that one of the 
gauge-taps, recommended by the Society, May 19th, 1858, 
will enter the bodies of their microscopes to the extent of 
three tenths of an inch.” 
* For this purpose it will be necessary to omit the cylindrical 
fitting beyond the inside screw recommended by the sub- 
committee (‘ Trans.,’ Jan., 1858, p. 39) ; retaining, however, 
the plain collar on the object-glass to facilitate its attachment.” 
“‘N.B.—A supply of taps and screw-tools is now in the 
hands of Mr. Williams, the Assistant-Secretary of the 
Society.” 
The President announced that in consequence of the 
soirée on May 5th, the ordinary meeting of April 27th would 
not be held. 
May 5th, 1859. 
The annual soirée was held this evening at the South 
Kensington Museum. Although somewhat removed from 
the centre of the metropolis, the rooms of the South 
Kensington Museum offer so many advantages for a large 
gathering, that from the time the Council had obtained the 
permission of the Committee of Council on Education to hold 
their annual soirée in this magnificent suite of apartments, 
they lost no time in making arrangements for a display of 
microscopes such as had not been seen in the metropolis
