tion whereof, there is a Difpuce between this Author and 
one Mv. Le l*'eA;ire, each pfnhem eft^eming it a Difcovery 
worth contending for. Mr* -De H/>e rtiakes the greatefc 
quantity of this Equation to be thirteen minutes, in the mean 
diftance of the Sun, to be added to the Moons place in Sep- 
tember and fuWJfafttd in March which Le Fehure allows to 
be but 1 1'. 9". If there be any thing d ue to the firft Pxopo- 
fer of this Difcovery, it will appear that neither the one or 
the other of thefe Pretenders have any juft claim to it 5 for 
that it is conceived, that the whole matter is fully and am- 
ply fet forth in the Appendix to the Catalogue of the South- 
ern Stars, pubhfhed in London by £. HitUey in the Year 1679^ 
and foon after Tranflated mto French, and printed in Park >

Hence it fhould feem, either that this inequality is nioft 
Juftly ftated by the exaft Coincidence of the Conclufions of 
two fo different Inquirers 5 or that the latter having feen 
the afore-cited PaflTage, and finding it warranted by Obfer- 
vation, might think it an Invention not unworthy a French-' 
man : And whereas Mr- De la H/z-e feems to conclude, that 
this Equation ceafesinthe Quadratures, and is greatefl in
