Wool is readily distinguished from otherfibres by means of the micro-scope, being built up of an im-mense number of epithelial cells,scales or serrations as shownin the accompanying illustrationFig. 56, representing a typicalwool fibre viewed under the mi- Fig. 56. croscope. The amount of scalesfound per square inch varies with reference to quality—the finer grades having more,and the coarser less. If these scales can not be readily seen treat the fibres in questionwith ammoniac copper, and the scales will become distinctly visible to the eye duringthe swelling up of the fibres. Another prominent feature characteristic to wool is its
