Facts to be RemcmJcrcd-Whcn clouds are
small and round like Il dappe gray, moving with
north wind, fair weather may be expected for

but If in the rear they a sign that there will
be a change in the weather; hence the prognos-
tics: Ii cirrus clouds dissolve aud appear to

cirrus clouds form ia fnc weather, with falling

When, after n clear frost long strcaks of cirrus

they point to the northeast, thaw aud a south

any other quarter 70 east makes most people
feel uncomfortable aud produces headaches in

changes have the most violent effects when they
happen about the new or full moon. Its diff
cult TO ascertain IN what degree the directions
and changes of wind are under the influence of
electricity, but there nre many circumstances
which would incline one 10 believe that these
changes are dependent on some similar principle

wind is proverbially unhealthy. Casual changes
to east produce headache and nervous com
plants, and long contlnaed wind from that
quarter produces an unwholesome season. An
other curious fact is that with east winds good
astronomical observations cannot be made, the
luminous objects seeming to dance or wave
about in the iled of the telescope.
