with a little rain, followed. 9. Calm: grey sky, with the lighter modifications: 
at sun-set the clouds exhibited a splendid set of tints: close to the horizon wasa 
clear space, lemon-coloured ; above this, crimson lights, with shadows of grey and 
purple, in a variety of figures, streaked, waved, and clustered ; of those in the

Third Month.—1. Fair: windy. 2. A trace of solar halo about nine, in some 
Cirri, which soon subsiding went off with the wind to SE, grouping into forms 
like the crown of the Nimbus: Cumulostrati succeeded, which, p.m. gave place 
again to Cirrose obscuration, with a southerly gale and showers at night. 
3. a.m. Overcast: p.m, steady rain: at sun-set a hazy sky, and much vapour: a

of hail from a dense lofty Nimbus: the balls were opaque, in the form of a cone 
with a rounded base about Zin. diam,, and composed entirely of striz# meeting at 
the apex of the cone: we have bad similar hail repeatedly of late: frost (after

The Aurora Borealis, which has appeared several times in the period, has not 
been well seen, for want of a clearsky, in this neighbourhood, On the 2dand 3d 
of the present month there were violent thunder-storms to the W and S, the latter 
of which came as near to us as Tunbridge, but neither of them was much perceived 
here, save in the evident electric state of the clouds on the latter evening.
