Seafons of the Year. Upon comparing the Obfer- 
vations with each other, it was difeovered, that in 
both the fore-mentioned Stars, the apparent Dif- 
ference of Declination from the Maxima , was al- 
ways nearly proportional to the verfed Sine of the 
Sun’s Diftance from the Equino&ial Points. This 
was an Inducement to think, that the Caufe, what- 
ever it was, had fome Relation to the Sun’s Situa- 
tion with refpeCt to thofe Points. But not being 
able to frame any Hypothecs at that Time, fuffi- 
cient to folve all the Phenomena, and being very 
defirous to fearch a little farther into this Matter ; 
I began to think of ereCting an Inftrument for my 
Self at JV an fled , that having it always at Hand, I 
might with the more Eafe and Certainty, enquire 
into the Laws of this new Motion. The Conside- 
ration likewife of being able by another Inftrument, 
to confirm the Truth of the Obfervations hitherto 
made with Mr. Molyneux 9 s, was no fmall Induce- 
ment to me; but the Chief of all was, the Oppor- 
tunity I Should thereby have of trying, in what 
Manner other Stars were affeCted by the fame Cauie, 
whatever it was. For Mr. Molyneux's Inftrument 
being originally defigned for obfervingy c Draconis fin 
order, as I faid before, to try whether it had any 
fenfible Parallax ) was lo contrived, as to be capable 
of but little Alteration in its Direction, not above 
feven or eight Minutes of a Degree : and there being 
few Stars within half that Diftance from the Zenith 
of Kew , bright enough to be well observed, he 
could not, with his Inftrument, throughly examine 
how this Caufe affeCted Stars differently fituated with 
refpeCt
