“ I connected the Plumpton Bocks with the red sandstone 
which, underlying the magnesian limestone of Knares- 
borough, is unequivocally Permian. But I could not con- 
nect the two stratigraphically, and I came to my conclusion

Plumpton Eocks to the well-known beds of the German 
Eohte Liegende.

The President said that, on Friday the 10th instant, he 
observed, at Douglas, in the Isle of Man, a splendid display 
of the aurora borealis. At 8 p.m. it appeared as an arch of 
a greenish colour, extending from west to east, through the 
tail of the Great Bear. Afterwards, at 10 o’clock, the same 
kind of arch was observed with another higher up, which 
ranged west and east through the Pole Star. At this time 
numerous streamers and flashes of light of a green and 
yellowish-white colour flashed up from near the horizon to 
the zenith, from east, south, and west ; those towards the 
west had a reddish hue. The sky was beautifully clear and 
the light from the aurora was greater than ever previously 
observed by him.
