CLIQUE FORMATION.

To I'he pr,ss nnH Uulot,.n,

nation, ! spoke principally oil the cumu-
lus, but thele are other formations
which have been classified by the cele-
brated meteorological Luke Howard, and
are now universally adopted.
by this nomenclature clouds are
divided into seven kinds--the first three
being slmplc--as the cirrus, the;cumulus
and the stratus, and four other kinds
intermediate or compound, the cirro-
stratus, the cumulo-stratus and the
cnmulo-cirro-stratus or nimbus, better
known as the rain-cloud.
THE CIRRUS CLOUD,
consists OF long, slender, parallel, wavy,
or diverging fibrcs which frequently as
sumo various forms, a3 mare or horse
tails, cat tails, twisted tufts-othcrs
resemble birds plumagc, or rlongitudnat-
cd and palmated bands with slender
tilamcnts stretching i'll any or all dircc-
tions across the blue sky like white pen
clllcd lines. This cloud is supposed to
consist of minute particles or crystals OF
ice or snow-ilakcs; it has the least dem
slty, and the greatest variety Of extent
and figure; it is the cloud of GREATEST
elevation, seldom being seen ut n less
elevation than four miles, and frequently
being observed as high as ten miles. In
the balloon ascent made by Gay Lussac,
IN September, 1903, when at height OF
$4,000 feet lie says cirrus clouds were
floating apparently at great height
above him. The cirrus is the first cloud
seen after a spell of clear, pleasant
weather, appearing in long, slender
streamers or white lines stretching in
the northern hemisphere from north to
south, or from southwest to northeast
