 added all the way, will give true time.

A Proposal to make the Poles of a Globe of the Heavens move in a Circle 

 round the Poles of the Ecliptic. By the Rev. Ebenezer Latham, M. D. and 

 F.D.M. N°447, p. 201. 



As we now have the globes of the heavens, they are only formed for the 

 present age, and do not serve the purposes of chronology and history, as they 

 might, if the poles on which they turn were contrived to move in a circle 

 round those of the ecliptic, according to the present obliquity of this. By 

 this means we might have a view of the heavens suited to every period, and 

 that would answer the ancient descriptions, those of Eudoxus, for instance, 

 who is supposed to borrow his from the most early observations ; and of Hip- 

 parchus, &c. Nor could any contrivance better enable the lowest reader to 

 judge of the merits of the controversy about the Argonautic expedition, as far 

 as it depends on this: for it will verify to the sight the path of the colours, &c. 

 at any time. 



N. B. That globes, to answer the end here proposed, though differently 

 constructed, had long before been made and published by Mr, Senex, who at 

 the next meeting of the R. S. gave the following account of his contrivance. 



A Contrivance to make the Poles of the Diurnal Motion in a Celestial Globe 

 pass round the Poles of the Ecliptic, Invented by John Senex,* F. R. S. 

 N"447, p. 203. 



The poles of the diurnal motion do not enter into the globe, but are affixed 



• Mr. Senex, F. R. S. was a bookseller, and a celebrated maker of globes and planispheres, &e. 

 He died Dec. 30, 1741.
