The work, which is very well illustrated with designs, machines, and wool fibres, will be a useful addition to our textile literature."--_Northern Whig._ "It gives an account of its subject which is both valuable and instructive in itself, and likely to be all the more welcome because books dealing with textile fabrics usually have little or nothing to say about this way of decorating them."--_Scotsman._
