October :. His distance is now about 367. .00,0 600
miles, and his apparent diameter
is 47A seconds Of arc, or about equal
to a circle OF Is inches diameter seen at
distance OF one mile. To tho naked eye he
appears much larger than this, on account Of
the spreading OF bis rays, due to intense bright
ness. small glass Is, however, sufficient to
destroy great pnrt Of this effect; and good
opera-g glass will make him seem even smaller
than be appears to the unaided eye fsbright-
ness will be somewhat intcrfercd with By the
moon until about Wednesday night After that
he will he very interesting object, and will
doubtless enchain the gaze Of hundreds |
