These we saw in the evening in the south-east, half way up to the
zenith. They are two dark spots, one larger than the other, about
twenty paces apart, not far from two yards broad. No stars appear in
them. The telescope shows them to be openings into a milky way or
paths of star dust, groups of heavenly bodies so many and so distant
that their light is confused. Hence these openings in the bright
heavens have the appearance of clouds, though they are not clouds;
but the light which is in them is darkness, its excess confusing the
irradiation.
