TRADE WEIGHTS FOUND AT MELANDRA. 



167 



list of trade weights by excluding therefrom the single bronze 

 weight No. 9A, weight 405.6 grains, which is probably an 

 example of the Roman tmcia {circ. 421 grains) in a somewhat 

 damaged or corroded condition, as therein suggested, No. 6 

 as being evidently in a damaged and defective condition, and 

 No. I as unconformable. 



The revised table of the remaining seven trade weights, which 

 are all of lead, will then be as follows :— •

The figures in the third column are obtained by dividing the 

 present weight by the fraction in the intermediate column. 

 Since 288 is the least common multiple of the denominators, it 

 follows that a minimum weight was employed corresponding to 

 the Roman scripulum= ^\^ libra, and weighing 16.55 grains. 

 A ^veight corresponding to the Roman uncia (Jjth lihra), and 

 weighing 396 grains, is also indicated by three punch marks on 

 No. 15 (.1^-^= 396). 



By reference to the photograph in the original paper it will 

 be seen that the largest of the above series. No. 19, bears one 

 punch mark, and from the table, that its weight is only twenty- 

 six grains less than that of the Neath unit, a discrepancy no 

 doubt due to its corroded condition. On the other hand
