circulation than tJie present crown and half-crown pieces, the 

 former of which, in particular, from its large size, is ill adapted 

 for carrying in the pocket. 



As the highest denomination of money in the decimal scale 

 proposed is the " half-pound," all gold coins ought to have 

 some multiple value of the same. We have already the half- 

 sovereign often shillings and the sovereign of twenty shillings, 

 to which might be added a <ioMi/^-sovereign. In this way the 

 consecutive values of the gold coins would also form a geome- 

 trical progression, having 2 for a common ratio, as in our 

 proposed table for silver coins *. 



Many complaints have been made of the want of a silver 

 coin of a lower denomination than the sixpence, purchasers 

 having frequently the inconvenience of carrying five penny- 

 worth of copper about them. There is no doubt that it would 

 be a great convenience to the public to have a 25-cent piece 

 in silver, which would be, in fact, a silver threepenny piece. 



It now only remains to give an example or two of the sim- 

 plicity and readiness of arriving at results by the adoption of 

 the proposed decimal scale. Suppose that we have 35 tons, 

 at 9/. Il5. Q\d, per ton: — to find the amount. 



9/. Il5. ^\d, = 19-152 half-pounds.
