Account of a White Solar Rainbow. 177 
visible. : I never saw a more perfect bow, nor 
one more distinctly defined in every part. Its 
apparent distance from me was about one hun- 
dred yards; and its span did not appear to 
exceed one hundred and twenty yards. Its 
breadth (apparently) exceeded that of any 
Rainbow I ever noticed: I should say it was 
double the breadth of rainbows in general, or 
nearlyso. It was ofa very greyish cast, simi- 
lar in appearance to a lunar rainbow. It 
never assumed any of the usual colours of the 
rainbow. Near the ground, the colour was 
brighter than it was nearer the centre. In 
each leg, about an equal distance from each 
edge, was a streak of white, reaching appa- 
rently to the height of sixteen or eighteen 
yards, of peculiar brightness. During a 
considerable part of the time, at least while 
the bow was best defined, these streaks might 
be said to be rather brilliant. They conti- 
nued more or less visible during at least 
twenty minutes. 
Such were the particulars connected with 
this phenomenon which chiefly attracted my 
notice. I have simply stated facts; and leave 
it to scientific men, shouldany such deem the 
subject worth their notice, to explain them. 
If the phenomenon which I have attempted to 
describe, be of more frequent occurrence than
