The 22 °f^,Greenwich;Apr. at about 2 a Clock aster the Midnight following, I säw the Tail raiscd bj Mr. Flam-almost perpendicular to the Horizon ; soon aster the Head appeared through athin Vapour, from which the Tail pointed, as near as I could guesi, upon the* in the Kjice of Casswpeia, its Length being about 6 Deg. and Breadth at theTop about 7 or 8 Min. Viewing the Head with a Telcscope of 16 Foot, Ifound it was not perfecti/ Round, but Indented, and not near one Min.

Diameter. Afterwards I hastened to Measure its Distances from several FixedStars, which were as follow.
