For each such distribution, the expected average length of fibres obtained on the basis of number and weight of fibres has been estimated. Some test results are presented to show their extent of agreement with the values estimated analytically. The causes for discrepancies between experimental values and those expected from analytical relations are discussed. For routine testing of fibre length, the need for standardizing the methods of sampling and testing has been stressed.</span>
