C 166 ) p. 172. The library in the Bruchium was the more ancient; it was 

 destroyed in the burning of the fleet under Julius Caesar. The library at 

 Rhakotis made part of the " Serapeum," where it was combined with the 

 museum. By the liberality of Antoninus, the collection of books at Pergamos 

 was incorporated with the library of Rhakotis.

 of Alexandria, like all academical corporations, together with much good 

 arising from the concurrence of many workers, and from the power of obtain- 

 ing material aids, had also some disadvantageous narrowing and restraining 

 influence. Hadrian made his tutor, Vestiiius, High Priest of Alexandria, and 

 at the same time Head of the Museum (or President of the Academy)

 ment of a degree the first Hellenic one, as a very ancient Chaldean determi- 

 nation of the magnitude of a degree in camels' paces is not improbable. See 

 Chasles, Recherches sur 1'Astronomie indienne et chaldeenne, in the Comptes

t 271 ) p. 175. The latter appellation appears to me the more correct, as 

 Strabo, lib. xvi. p. 739, cites "Seleucus of Seleucia, among several very 

 honourable men, as a Chaldean well acquainted with the heavenly bodies." 

 Probably Seleucia on the Tigris, a flourishing commercial city, is here meant. 

 It is indeed singular, that the same Strabo speaks of a Seleucus as an exact 

 observer of the ebb and flood, calling him also a Babylonian (lib. i. p. 6), and 

 subsequently (lib. iii. p. 174), perhaps from carelessness, an Erythrean.
