Excerpt from the 'Wool' entry in the Encyclopaedia Perthensis (pp. 261-264 plus an engraved plate). It covers the grading and sorting of fleeces and the regions known for fine wool, and the British Wool Society founded in Edinburgh in 1791. It also describes Edmund Cartwright's patented wool-combing machinery and gives definitions of 'woolfell' and 'woollen'. Most of the text is the 1794 patent specification of Mr Harmar of Sheffield for machines that raise a shag on woollen cloth and crop or shear it, described figure by figure with lettered parts. The final plate shows the cloth-dressing machines, wool-combing machinery, and yarn mills.
