[1] *Note that there is some little light reflected from those parts of this black spot where the glasses by reason of their convexity & some little uneavenness of their surfaces do not come to absolute contact. For by viewing the sun by reflexion from this spot, not only the verges of it became lucid, but divers lucid veins & specks appeared into the midst of the thickness. But {yet} some parts of the spot seemed still {as} black as before {illeg} I {take} {illeg}.
