                  partem proportionalem.

                  Ut si uni gradui anomaliae mediae respondeant 24' 17" coaequatae, quid
                  competit minutis 49. 23"?

                  Summa "~3Ô348Ôr"dat 9' 15", tantum competit scrupulis 49. 23".

                  III. PRAECEPTUM.

                  Dato diurno Solis vel planetarum 5 unius, coîligere aliquot horarum
                  rnotum.

                  Si diurnus minor est quam 60', ut in Saturno, Jove, Marte et in Sole,
                  quaere eum in sexagenaria, numerurn horarum in quadrivicenaria, et adde
                  eorum Logarithmos; summa in Logarithmis quaesita eruet ex sexagenaria
                  partem horis competentem.

                  In Sole, Venere, Mercurio, si diurnus est inter et 2°, quaere pro-
                  portionalem partem de excessu supra eamque ndde ad id, quod horis datis
                  in sexagenaria respondet per caput 4. In Mercurio vero, si ejus diurnus
                  superat 2°, partem proportionalem de excessu adde duplo illius quod horis
                  datis respondet in sexagenaria.

                  Aliter, quia diurnus plerumque constat integris scrupulis sine appendice
                  secundorum, quaerere illa poteris non in sexagenaria, scd inter absolutos,
                  prolongata prius, ut cap. 8. docui, et tune, quae ex Logarithmis colligitur
                  summa, quaesita in Logarithmis, rursum inter absolutos ostendet partem pro-
                  portionalem decurtandam iterum totidem locis.

                  sent illa 491 30" addendaque 14' 1", ita collegissemus û3' 1".

                  Horarium elicere ex motu aliquot horarum datarum, minore quam 60'.
                  Auferatur Logarithmus horarum datarum, in quadrivicenaria quaesitarum,
                  a Logarithmo ex sexagenaria scrupulorum, horis competentium; residuurn,
                  ut Logarithmus, ex sexagenaria exhibebit horarium. Exempla sunt facilia
                  et obvia.

                  V. PRAECEPTUM.

                  Data separatione diurna minore quam 60' et distantia planetae ab alterius
                  aspectu, minore ea quam est diurnus, prode.rc horarum intervallum
                  respondens.

                  In sexagenaria vel etiam inter absolutos quaesitis diurna separatione
                  et distantia, Logarithmes illius aufertur a Logarithmo bujus, residuum, ut
