weigh 5760 Rods, a burden which no beast is able to carry. It is 

 therefore clear that one Korr contains 60 Qafyz or 12 camel loads 

 of 480 Rods each. Another statement of the Qamus says, 1 Korr 

 = 40 Irdabb. The Korr is an 'Iraqian (Babylonian), and the Irdabb 

 an Egyptian measure. One Irdabb = 24 £a' or 6 Wayba. If the 

 Wayba is taken at 24 Modd, and the Modd at 1J Rods, these two 

 valuations agree ; for 24 X 8 = 24 X 6 X H = 192 Rods = 1 

 Irdabb. Consequently the weight of a Korr = 7680 Rods. We 

 must bear in mind that this is a reduction of the largest Iraqian 

 measure of grain to Egyptian measure, and it is very likely that the 

 value of the Irdabb is stated in Egyptian Rods, the weight of which 

 I do not know ; we can therefore make no use of this definition of 

 the Korr. Grolius gives the value of the Korr, on the authority of the 

 Destur alloghat, at 7100 Rods. Tbis approaches to the result which 

 we have just found ; the question is only, what kind of Rod is meant, 

 and by what means did the author arrive at this result. 



The Jaryb is defined in the Qamus as follows : 1 Jaryb = 4 

 Qafyz ; 1 Qafyz = 8 Makkuk ; 1 Makkuk = 3 . Kaylaja ; and 1 

 Kaylaja = l-£ Mana. We see that this statement is a continuation 

 cf the one given above in a tabular form; and it seems to be an 

 abstract of a systematical comparison of 'Iraqian weights and mea- 

 sures ; and we therefore keep to it. Consequently 15 Jaryb = 1 

 Korr. I now continue the above table taken from the Qamus.

Consequently one Korr is equal in weight to 486080 Mitkqals or 

 6750 Roman pounds. I ought to observe that Abu Yusuf mentions 

 a Jaryb of 7 Qafyz, and that he as well as Ibn Sad say that a man 

 may live on a Jaryb of grain one month. I should think that fifty 

 or sixty Roman pounds would be sufficient for the support of a man ; 

 and as the Jaryb of 7 Qafyz contains 787J Roman pounds, I am 

 at a loss, how to explain this statement. 



The linear measures of the Arabs are probably not essentially 

 different from those of the Greeks. 1 Haschimite or Royal cubit ==
