datinn, I mu ft obferve, that the concurrence of thole (even 
principal fhfrs cannot but give home value to an hypothecs that 
will fimplify the celeftial motions in general. We know that 
the fun, at the diffance of a fixed ftar, would apppear like one 
of them ; and from analogy we conclude the ftars to be funs. 
Now, finee the apparent motions of thefe feven frars may be 
accounted for, either by fuppofing them to move juft in the 
manner they appear to do, or elfe by fuppofing the fun alone 
to have a motion in a direction, fomehow not far from that 
which I have afiigned to it, I think we are no more authorifed 
to luppofe the fun at reft than we fhould be to deny the diur- 
nal motion of the earth, except in this refpedt, that the proofs 
of the latter are very numerous, whereas the former refts only 
on a few though capital teftimonies. But to proceed : I have 
only mentioned the motions of thofe feven principal ftars, as 
being the moft noticed and beft afeertained of all ; I will now 
adduce a farther confirmation of the fame from other ftars. 
M. de la lande gives us the following table of the pro- 
per motion of 12 ftars, both in right afeenfion and declination, 
in 50 years *.
