pofal I would make relating to an Improvement in 
the Conftruftion of the Globes of the Heavens. As 
we now have them, you know they are only form'd 
for theprefent Age, and do not ferve the Purpofes of 
Chronology and Hiftory, as they might, if the Poles 
whereon they turn were contriv'd to move in a Circle 
round thofe of the Ecliptic, according to the prefent 
Obliquity of this. By this Means we might have a 
View of the Heavens fuited to every Period, and that 
would anfwer the antient Defcriptions, thofe of Eu- 
doxus, for Inftance, who is fuppofed to borrow his 
from the moll early Obfervations 5 and of Hipparchus , 
Nor could any Contrivance better enable the 
lowed Reader to judge of the Merits of the Contro- 
verfy about the Argonautic Expedition, as far as it 
depends on this : For it will verify to the Sight the 
Path of the Colures, at any Time. I thought to 
have tranfmitted a Scheme of the whole, in which 
the Equator muft be fix'd to the brazen Meridian, 
But it is eafily underftood, and can only wait the Ap- 
probation of fuch great Judges to recomipend it to 
tthe Artifis.

That Globes, to anfwer the End here propofed, 
tho* differently conflrufted, had long before been made and 
publifhed by Mr. Senex, who at next Meeting gave the fol* 
lowing Account of his Contrivance.-
