Dr. Brinkley’s remarks on 
Had these or any other stars exhibited a negative parallax 
exceeding a small fraction of a second, it would have been 
decisive against parallax, or had these exhibited any discor- 
dances, it could not have been from parallax, as the effect of 
parallax in declination for these stars is a very small part of 
the whole. The observations of the Pole Star also point out 
no parallax for that star. They have been very numerous 
and made at the same time as the observations of a Lyras, and 
therefore, according to the hypothesis of Mr. Pond, they 
should have exhibited a discordance even greater, this star 
being so much further from the zenith than * Lyrae. But no 
such thing takes place either with respect to the observations 
above or below the Pole. 
I ought, perhaps, to apologize to the Society for repeating 
these circumstances ; they are fully stated ; and the very ob- 
jections that have been brought forward, in the paper under 
consideration, have been anticipated in my Paper in the Phi- 
losophical Transactions, 1821. 
If it should appear hereafter, by any decisive observations, 
that I have been mistaken in having attributed the differences 
of the zenith distances which I have met with in several stars, 
to parallax, I trust I shall not be found to persevere in the 
opinion I at present hold. Recent circumstances have led me 
to adhere more strongly to that opinion. The alleged per- 
manency of the arc between 7 Draconis and « Lyrae, seemed 
to furnish a powerful argument against me, and I have here- 
tofore represented it as such ; now, I consider the Greenwich 
observations of this arc, if not favourable, certainly not ad- 
verse to parallax.
