CELESTIAL MEASURINGS AND WEIGHINGS. iSl

 attempt to lay before our readers the actual state of our 

 positive knowledge of these subjects ; of the methods by 

 which it has been attained ; and of the history of their 

 development; and to give them a distinct conception 

 of the several links which connect the British standard

 unit of length ; and its representative, when it is required 

 to test the correctness of one in vulgar use, or to multiply 

 and disseminate copies of itself for purposes of ordinary 

 mensuration. Thus, among the Jews, we find (Exodus 

 xxx. 2) the cubit* identified as equal to either of the 



* This cubit is presumed to be identical with the Egyptian cubit, 

 still preserved, of the Nilometer.
