COFFEE PRICES SINCE 1845. 167 
and all the subsequent figures are calculated from that 
Datum line. Thus as regards coffee (Col. 1), the price 
of Ist July, 1857, was equal to 151, or 51 per cent 
above the average prices of 1845-50. In order to 
ascertain the percentage rise or fall between one date 
and another—as for example Cojfee—comparing 1st 
July, 1857, when the figure was 151, with lst Janu- 
ary, 1866, when the figure was 179 or a difference 
of 28, the rise per cent has to be measured with 
the quantity 151, and gives of course a result of 19 
per cent as the real advance. In the course of so long 
a period of years as 1845-71, some variations have 
inevitably arisen in the mode of quoting prices in 
the usual Prices Current. In all such cages the near- 
est approach possible has been made to an uniform 
quotation throughout the Table. In Raw Cotton espe- 
cially there have been considerable change of qualities 
introduced by the large use of Indian, &c., kinds. 
In Tea and Sugar also changes have occurred in the 
kinds most usually quoted.” 
In this case we include the columns for sugar and 
tea as well as for coffee :—
