It is sometimes insufficient in the spectrophotometry of coloured materials for the determination of their colour coordinates on the C.I.E. system to take measurements at intervals of 10mu. instead of the standard interval of 5mu. Special tables have been computed for use in these cases which give with less labour results indistinguishable from those which would be obtained from the use of the standard observer tables.
