BOOK VI. XXXIX. 220 



The same authorities also place two parallels before 

 what we made the starting point, the first running 

 through the island of Meroe and Ptolemy's Lodge 

 built on the Red Sea for the sake of elephant- 

 hunting, in which parallel the longest day will be 

 12^ hours, and the second passing through Syene 

 in Egypt, with a 13-hour day ; and they also add 

 half an hour to each of the parallels up to the last. 

 So far as to the geography of the world.
