VI. ^art of a Letter from the GfeVerend Mr W. Der- 
ham, F. % S. concerning a Glade of Light ob- 
ferVed in the Heavens. 
Hpminfter, March 28, 1706. 
A S I was obfervjtig the Immerfions of the 3d and 4th 
Satellite of j, on the 20th of this month in the 
Evening, I efpyed a very odd fort of Light in the Con- 
ftellation of y , the lower end of which was below . 
the Bull’s Eye, and the other a good way above it, 
and that Star about the middle of the lower end there- 
of, as in Fig. 3. which doth reprefent its appearance 
to me. This Glade of Light had the fame Motion 
that the Heavens had, and was much like the Tail of a 
Comet, but pointed at the upper end, as in the Figure. 
This Light, I doubt not, is fuch as Dr Childrey firft ob- 
ferved in England, and which CaJJint and others after- 
wards obferved in France, as Dr Hook faith. I am forry 
that the following Nights were Cloudy 5 and although 
EaJlar-cLay Evening was fair, yet I forgot it unluckily then. 
And Eajisr- Monday being Cloudy in the Evening, 1 could 
not obferve it a fecond time till Tuefday laft, and then it 
was gone.
