EXEMPLIFICATION In order to exemplify the foregoing instructions, let the first point of Aries be supposed as the preceding place, and the first point in Gemini the succeeding; and let the latitude of the country, to which the operation relates, be such as will cause the longest day to consist of fourteen hours[165]; and where the horary magnitude of the beginning of Gemini will be about seventeen equatorial times.[166] [165] This, in the Northern Hemisphere, would be the latitude of Alexandria (where Ptolemy flourished), or, in his own words, that of the 3rd Climate, passing through Lower Egypt, numbered 30° 22′.—_Vide_ extracts from the Tables of the Almagest, inserted in the Appendix.
