VI LIGHTS OF THE CHURCH AND SCIENCE 221

 most, accordiug to the conceptions of the Biblical author. This 

 very simple conclusion, however, is never drawn by too many 

 readers of the Bible. But one need only cast one's eyes over 

 the tenth chapter of Genesis in order to become acquainted with 

 the geographical horizon of the Jews. In the north it was 

 bounded by the Black Sea and the mountains of Armenia ; 

 extended towards the east very little beyond the Tigris ; hardly

 motive, or generative incident, of the whole story 

 is to be sought in the occasionally excessive and

 by water to a depth certainly greater, probably 

 much greater, than fifteen cubits, or twenty feet 

 (Gen. vii. 20). The inundation prevails upon the 

 earth for one hundred and fifty days ; and then 

 the Hood gradually decreases, until, on the seven-
