fication of certain coal measure plants, particularly to the 
Volhnannia sessilis of Presl. Mr. Binney said he had in 
his cabinet two specimens showing organs of fructifica- 
tion very similar to those described by Professor Goeppert, 
and evidently closely allied to them. These specimens were 
from the carboniferous strata of Great Britain, one from the 
mountain limestone of North Wales, and the other from 
the upper coal measures at Ardwick, near Manchester, so 
in all probability the learned Professors specimen came 
from carboniferous and not liassic strata. The fossil is 
the fructification of some species of calamites, according 
to the opinions of the best fossil botanists of the day. 
Mr. W. L. Dickinson communicated a paper containing 
the results of calculations relative to the Occultation of the 
star Aldebaran by the Moon, January 16, and to the Eclipse of 
the Sun, March 5, 1867, visible here. The calculations have 
been made for the observatory of Robert Worthington, Esq., 
F.R.A.S., Crumpsall, near Manchester, Lat. 53° 30' 50'0" N., 
Long. 0 h 8 m 56*16 s W. The elements used in the computa- 
tions have been obtained from the Nautical Almanac.
