_ After various suggestions, it was resolved that the next Micro- 
scopical Meeting be devoted to practical instruction in “mounting in- 
fluid,” when it was hoped different Members would show how it was

The Meeting then became a Conversazione, when some very 
interesting and beautiful objects were exhibited by Messrs. R. Glaisyer, 
Hurst, F. E. Sawyer, W. H. Smith, and Wonfor. 
During the evening Mr. Wonfor distributed among the Members 
present portions of the wings of butterflies and moths, and of the wing 
cases and bodies of beetles from the Museum, and which were in too 
broken and damaged a condition to be of any avail for Museum 
purposes, but which were thought might be useful to Microscopists.

GREYWETHERS, OR DRUID STONES. 
DEFINITION. 
Throughout the western chalk districts of England, and 
following more or less the lines marked out by the middle and lower 
series of the Tertiary Eocenes, masses of stone had been observed, 
in some places profusely scattered and of huge dimensions, in others 
sparingly so, and of comparatively insignificant size. Aubrey wrote of 
them under the head of Sarsden or Sarsdon stones; and considered that 
“the name owed its origin to a villagenear Andover called Sarsden, z.e. 
Csarsdene, perhaps don, Czesar’s-dene, Czesar’s-plaine, now Salisbury- 
plaine.” There was another derivation from Saracen, meriting more 
respect. The Latin Sax had been suggested as fixed to them in 
Roman times, subsequently corrupted to Sarvsex by the Romanized 
Britons. Another derivation had been found in the Anglo-Saxon se/- 
stan, great-stone. One other solution, the Saxon ses, a stone, the 
plural of which, sessan, came very near to s@sen or sassen, the name 
by which they were known among the Berkshire rustics,
