729(134)PHYSICES ELEMENTA ut cum ſemidiametro Telluris conferantur; & Paralaxis pen-
det à ratione, quam ſemidiameter Telluris ad diſtantiam Pla-
netæ habet; idcirco ipſius Martis, in oppoſitione cum Sole,
111108. Paralaxis obſervationes ſubtilliſſimas effugit.
Ubi Parallaxis datur, adſcenſu corporis ſupra horizontem
221109. minuitur, & in Zenit nulla eſt.
Altitudo apparens ſiderum, mutatur etiam ex aliâ cauſâ,
quæ reſpectu omnium corporum Cœleſtium indeſcrimina-
tim locum habet. Ex Atmoſphæræ refractione radii infle-
331110. ctuntur , & Sidera altiora apparent ; quo tamen 441111. ſunt, eo minor eſt hæc inflectio ; quia radii minus 551056.66624.77639. in Atmoſphæræ ſuperficiem incidunt. In Zenit refractio
881112. nulla eſt ; etiam ad diſtantiam viginti, aut triginta, 99629. duum à Zenit ſenſibilis non eſt.
Cùm ex hac refractione Sidera eleventur, viſibilia ſunt
10101113. antequam ad horizontem perveniant.
Hæc omnia generaliter Telluris ſuperficies ſpectant, hu-
1111TAB. XXIV. jus variæ partes nunc ſunt examinandæ: determinantur hæ,
1212fig. 2. referendo ad Tellurem varios circulos, quos in cœlis antea
conſideravimus; ſic in Tellure conſideramus Æquatorem,
13131114. Meridianos, Tropicos, circulos Polares; quibus circulis eo-
dem modo Telluris ſuperficies dividitur, ac, circulis in cœ-
lis, ſphæra ſtellarum fixarum: Quare circuli hi ita ſibi mu-
tuo reſpondent, ut ductâ lineâ ex centro Telluris ad circu-
lum in cœlis, hæc per circulum in Tellure tranſeat. Si po-
li fuerint P, p, Æquator erit E e, Tropici T T, t t, cir-
culi polares A A, a a.
Definitio 12.
Meridianus Loci dicitur ille, qui per locum ipſum tranſit.
14141115.
Hujus planum ad Horizontem eſt perpendiculare; quia
15151116. per centrum Telluris & ſpectatorem tranſit.
Linea Meridiana in Loco quocunque ducta, eſt pars Meri-
16161117. diani Loci .
17171101.
Definitio 13.
Latitudo Loci eſt hujus diſtantia ab Æquatore, id eſt,
18181118. arcus interceptus inter Locum & Æquatorem.
