Old-fashioned people (probably past sixty) will long adhere to their 
favourite sixpence and shilling, and perhaps will in time regard a shilling 
as the spurious half of a florin ; but the sooner both shillings and sixpences, 
fourpennies and threepennies, cease to be coined, the sooner will the decimal 
money fight its way into general use.

We may write, according to the new notation — as 1 pint = 7000 grams or 
1000 karats. 
960*8699 karats or 9608*699 pints; 
or, if a pipe be exactly 100 gallons, this will be expressed in either pipes, 
gallons, pints, or karats — 
P. G. 
960 gallons = 9 pipes 60 gallons =9 60 
g. p 
960*8699 = 9*608699 = 9608699 karats. 
Gallons or pipes are here expressed both by weight and measure , the karat 
being equally a measure of capacity or of weight. 
Again, since 
1 karat = part of a pint or pound, P. 
12 pipes 80 gallons 9 pints 0 ounce 9 drams 9 karats = 12*809099, 
which, at 120*95 francs per pipe, = 12*809099 x 120*95 
= 4)1549*2605 francs 
Divide by 10)687*315

A remarkable instance of the power of the new notation , concise and self - 
interpreting , without reduction. 
The great advantage of using reciprocals * for multiplication, instead of 
dividing by the constant , is shown by the following examples : —

45*359,5464 45*359, 
or 45 lbs. 359 karats are equivalent to 99*999 kilogrammes. Ry division, 
five places of decimals must be used — and we get 
Reciprocal number is such a number or fraction or decimal as multiplied 
by the number makes unity. Thus £ is the reciprocal of two, — of 260.
