The above diagram represents the rainbow, or
rather rainbows, seen on Tuesday last. The
primary and secondary bows exhibited nothing
remarkable in their appearance, except that the
several colours were unusually distinguishable,
being painted very dense shower, and no
distractions intercepting the suns rays. The
third or extraordinary bow was primary, its col
ours very distinguishable; its extremlties were
at the eXtremities Of the primary, and its yertex
above that Of the secondary; it consequently cut
the secondary in two points. The extraordinary
bow was not only so, in its existence, but also in
being sem-circle, while the was yet sew
eral degrees above the horizOn-time thirty min
utes after FIVE, p. NJ. We have never before
seen triple rainbow, and should, therefore, be
pleased, would some person give US the reason
ot this unusual appearance. We may, at least,
expect some hypotheses. L.
