 markable desire of truth in every part of science. 

 Pliny, after mentioning him and Thales, breaks out

 connect gods and men ! " Modern writers have 

 spoken of Hipparchus with the same admiration ; 

 and even the exact but severe historian of astrono-

 work has come to us entire, and who cannot refer 8 

 to the statement of an eclipse rightly predicted by 

 Halicon of Cyzicus without adding, that if the story

 loses all his bitterness when he comes to Hippar- 

 chus 9 . " In Hipparchus," says he, " we find one of 

 the most extraordinary men of antiquity ; the very
