Account. of two PARHELIA obferved February. 25th, 1790. 
By th Rev. HENRY USSHER, D.D, MRLA 
and F.R.S. 
On Thurfday, February 25, at four in the afternoon, as I 
was on my way from Dublin to the Obfervatory, I remarked 
that the fun’s light was uncommonly ‘pale; when getting a 
view of him clear of the houfes, J faw a corona and two 
pathelia; the parhelia were in the fun’s almacantar, and dif- 
played the prifmatic colours, the red being next the ‘fun; their 
tails, parallel to the horizon, were about a degree and an half 
long; there was no luminous circle parallel to the horizon, as 
fometimes happens. The corona in which the parhelia were 
formed was 22° 24° in femidiameter, as meafured by an Hadley’s 
fextant ; but it appeared to me that it was rather elliptical, the

longer diameter tending to the pole of the dipping needle, as ~ 
did manifeftly that of an halo round the moon which fucceeded 
this phenomenon, and which I have. frequently remarked be- 
fore.
