I reckon, above M, that 1 cannot but believe the Par- 
helia^ A, B, were neither in the Interiedion of N V O, 
with the great Circle, A B C D, nor of the Halo 
with the fame Circle, in one of which Circum- 
llances they have hitherto appear*d ; but between 
thofe two Points, and much nearer to the Circum- 
ference of the Halo. 
I thought I faw plainly at one time likewife, a 
fmall Portion of a Secondary Halo, if I may fo call 
it, as in the Scheme at P. It feem’d evidently to be 
an Arch of a Circle concentrical with the Plalo, and 
ting’d -with the Rainbow-Colours, whofe Diameters 
might perhaps be to that of the Halo, as 4 to 3 ; 
.but as it appear’d but for a little time, I would not 
be thought pofitive about it. 
I don^c at all remember, that during the time I 
watch’d it, lever obferv’d the great Circle AB CD, 
to be vifible within the Halo, between A and B, tho’ 
all the other part of it was fometimes very per- 
fecSf. 
This Face of the Heavens continued, tho’ with an 
Interruption of fome parts now and then, till about 
a quarter after eleven, when I left it, and could not 
return till about twelve, at which time the Sky was 
clouded over, (which had been before only hazy, 
a Pure Criterion of thefe Appearances.) and this 
Phaenomenon no longer vifible.
