1832.] On the Standard Weights of England and India. 443 



ingly, — the pound of standard silver being coined into 66 shillings in 

 England, it is evident that 11 crown pieces weigh 10 oz. troy, 

 leaving a very simple ratio for the conversion of one into the other : 

 the crown (436.36 grs.) is also nearly equal in weight to the avoirdu- 

 pois ounce (437^ grs,) and might be substituted for it practically 

 without much inconvenience : moreover, 1000 crowns are exactly 

 equal in weight to a cubic foot of distilled water at the temperature 

 of 15° cent. (59° Fahr.) (436363 grs.) 



From these data, it becomes a very easy problem to frame a system 

 of weights, measures, and coin connected together in simple ratios, 

 uniting all the benefits of decimal numeration, and still maintaining 

 tolerable accordance with the weights now in use. To give a general 

 idea of the combination proposed, without entering into its details, we 

 present the following scheme alongside of the existing system.

 Measures of Capacity. 

 1 oz. = 1 cubic digit (or 0.1 3 foot) = the proposed liquid ounce. 

 1000 oz. = 1 cubic foot of distilled water, at 59y Farht. or 15° cent. 

 10 oz. marked x = J pint. 

 20 oz. marked xx = 1 pint 

 40 oz. marked xxxx = 1 quart. 



160 oz. = one gallon (the present imperial gallon = 1 01b. av. or 10 cr. lb. + 200 eg) 

 8000 oz. = 500 lbs. = 1 hogshead = 50 gallons= 8 cubic feet = cube of 2 feet. 

 1000 lbs. = 1 pipe = 100 gallons = 16 ditto. 

 2000 lbs. = 1 ton or tun = 200 gallons = 32 ditto. 



It must be confessed, that the higher numbers in this scheme both 

 of liquid and solid weights are too much at variance to obtain easily 

 a footing in commerce, and in many respects as good a system might 

 have been framed with the preservation of one only of the pounds 

 and the present troy grain. 



The most fortunate hit in the scheme of the reviewer is in the for- 

 tuitous circumstance of 1000 crown-pieces, of our preseut coin, counter- 

 balancing precisely a cubic foot of pure water at 59°. A fact worth 

 carrying in the memory, at any rate, for although five shilling pieces 

 are but rarely seen in currency now-a-days, it may be convenient for
