with him a very good Brafs ^adrant of above tvib 
Foot Radius, and at the Dutch Settlement at Table Bay, 
Pendulum-Clock by correfpondent Al- 
titudes, on the 4th of Augufl 59' the 
diftance of the bright Limb of the Moon from the right 
Shoulder of Orion was obferv’d tobez5° 3'. And the 
next Morning Aug< 5. at 5I1. rT. 1 1", the fame Limb 
was diQant from Prccyon 25’. 57', and at 48'' 
from the Lucida Atiais 29'. 
It were much to be wilht that the Moon had, either of \ 
thefe Mornings, been accurately obferv’d at Greenvrich ‘ 
or Paris, or at fome Place in Europe, W'hofe Longitude ^ 
from them is well known. But that failing us, 1 had re- ■ 
courfe to the Period of the Lunar Motions, which is 
perform’d in 18 Years and ten or eleven Days, after 
which the Eirors of our Lunar Computations return 
very nearly the fame ; and I found among my own old 
Obfervations, one that tallyed well with that of the 4th 
of Augu(l. Viz^ Anno 1676. 23°. 13’'. ii'. 35". 
at Oxford, I obferv’d the Moon to apply to the Star in 
medio Collo Tauri, by Bajer markt A. The Star at that 
time was diflant from the Southern and neared Cufp of 
the Moon by the Micrometer zo'. 32". and at I3^ 17'. 
15''. when it Teem’d to immerge upon the bright Limb 
of the Moon, it was diftant from the Northern Cufp 
2?'. 20"; but this lefs certain by reafbn of the hazey 
Air. The Star at that time was in ^ 28°. y6^ with 
^1°. if .xd\ North Lar. whereby I found that our Lunar 
Tables, founded on Sir cor retd Theory of 1 
her Motion, gave her place at that time only two Mi- 1 
nutes too flow; which Error being allowed on the 4th I 
of Augujl 1694. the refult was, that 5\ 59'. at Cape Bonne f 
Efperance was London 53'. whence the difference of 
Longitude i6f degrees, fu&iently near what we had 
before determin’d. i
