"From 1790 to 1986 data is 'theoretical' averages. From 1987 to end of series, data is 'actual' averages. From 1790 to 1884 data is likely to be for rails, from 1885 to 1896 it is unknown at present if the data is for rails or industrials, and from 1897 to the end of the series the data is for industrials. From 1790 to 1896 it is unknown at present what divisor was used, if any. From 1897 to the high of 1914 data is homogenised to data after the exchange was closed by dividing this data by a divisor of approximately 1.370. From 1790 to 1884 data is computed from FSC monthly data. High is highest monthly value for the year, low is lowest monthly value for year, and close is December's value. From 1885 to 1896 it is unknown at present how the data was arrived at. From 1897 to the low of 1927 data is taken as highest and lowest daily close for the year, and the close as being the close on the last day of the year. From the high of 1928 to the end of the series, data is taken as highest daily high of the year, lowest daily low of the year, and close of last day of the year. Saturdays are included."
