might once for all fettle truly the Limits of the Land and 
Sea. This Work however being likely to be left to the Care 
andCurioficy of private Perfons, it may not.be amifs hereby 
to give notice of the prefent Opportunity of performing 
itj in this our Northern Heroilphere, by help of the fiequent 
Appulfes of the Moon to the mure Southerly of the Hy^des^ 
many of which fhe eciiples in each monthly Revolution, 
and will continue fo to do, during the Years- 1718, 1719, 
and 1720. 
Thefe Stars are but Three or Four in all former Cata- 
logues, but the Britijh of Mr FhmfieeJ encreafes them to 
Sixteen ; to them we have added Three others fomewhae 
fmaller, 'viz. c, i, and n in the Figure of the Hyadet here- 
to annext. In it the principal Stars are markt with Bayer*s 
Marks, and the reft with the Letters of the Italick Alpha* 
bet ; their Longitudes are fitted to the beginning of the 
Year *718, and being truly laid down, may ferve to in- 
ftrud the curious Obferver, when and where to look for 
them, when the Moon is among them. 
It appears by this Scheme that the Diftance between a 
and « or Palilicium, is about Nine Hours Motion of the 
Moon, in which time fuppofing her to pafs from one to the 
other, (he muft eclipfe y and e, and Four or Five of thofe 
about 9, and muft apply very clofe, with her Southern 
Limb, to all thofe which have about Six Degrees . South- 
Latitude i which would be a very entertaining Sight for 
the Lovers of thefe Arcs. But if the Times of-the Occul- 
tations of any One of thefe Stars, or even of anv Two of 
tliem in the fame Night, be accuratel obferved under di- 
ftant Meridians, the difference of thofe Meridians may be 
truly obtain’d thereby ; efpecially fince the Mooni Parallax, 
and all orner parts of her Theory thereto required, are at 
prefent fufficiently ftared and known. 
For the fake of fuch as are willing to make ufc of this 
Method, we have added the Places ot all the Hyaiet fitted to 
the prefent Time, and chiefly i.aken from the Britifh Cata- 
logue, which being faulty in the Scars wc call k and/, we 
have here rectified them-
