Abstract
IN the estimation of crude fibre at altitudes appreciably above sea-level, it is necessary to correct for lowered boiling points of reagents and consequent reduced speeds of reaction. When Todd1 estimated crude fibre in ten samples of plant materials at sealevel and at 6,200 ft., he calculated the percentage error involved in each instance and proposed three ways of correcting, namely: (1) by increasing the duration of the boiling; (2) by increasing the concentration of acid and alkali; (3) by carrying out the estimation by the standard procedure and applying a correction factor.
