LicHENS.—Mr. Wattam writes :— 
The smoke from the furnaces of Sheffield and Rotherham 
has apparently sufficient effect to deter lichens growing in either 
abundance or luxuriance, and the specimens met with were 
generally of but meagre growth. None of the woods investi- 
gated yielded a single filamentous form, and even foliaceous 
forms therein were scarce. The following species, which are the 
first records for the district, were noted, viz :— 
Parmelia saxatiis L., and form furfuracea Schaer, P. 
omphalodes Ach, P. caperata Ach, P. olivacea Ach. P. physodes 
Ach, Physcia parietina De Not, P. stellaris sub. sp. tenella Nyl; 
Lecanora ferruginea Huds, L. irrubata sub. sp. calva Nyl., L. 
parella Ach., Pertusaria communis D. C. form rupestris D. C. ; 
Cladoma pyxidata Fr., C. cervicornis Schaer, C. digitata 
Hoffm., C. macilenta Hoffm; Lecidea contigua Fr., L. con- 
fluens Ach. 
GEOLOGY.—Mr. C. Bradshaw, writes :— 
On the journey from Rotherham to Maltby, stone lifting 
tackle was seen from time to time, showing where exposures of 
economically important Coal Measure sandstones could be 
studied about Wickersley and Bramley. 
The route from Maltby to Roche Abbey was through the 
valley threaded by the Maltby brook. Careful observation of 
surface features lead geologists to surmise a junction between 
the Lower Magnesian Limestone, which occurs on both sides 
of the valley, and the Coal Measures beneath, though the latter 
are concealed by turf or other covering, save where the stream 
reveals a more or less satisfactory section. 
As the distance from the Abbey was diminished, prominent 
crags and faces of the picturesque limestone commanded 
attention, and there was some discussion as to the origin of a 
character, which, for want of a better term, might be called 
“honeycomb ’ structure.
