We cannot conclude our work without observing, that from the researches continually going on in botany and other branches of natural history, and, more especially, from those in chemistry, there can be no doubt that discoveries, which will materially improve the art of dyeing, must, from time to time, be made. Some of these, not yet generally known, in the hands of a few persons, have already been found useful; but individual interest is, of course, a great enemy to their being made public. Others, although public, are, as yet, of too doubtful a utility to be noticed here.

If we have not given forms for the employment of some articles in use by certain dyers, such as kermes for reds; French Berries, (rhamnus infectorius,) the Canada golden rod (solidago Canadensis,) the Barberry (Berberis vulgaris,) and the French marygold, (Tagetes patida,) for yellows, &c. &c.; it is not to be concluded that such are not good in their kind, and might not be used occasionally with advantage. But as our object has been to give the best methods of dyeing the various colours, it would be impossible to notice many others in a manual of this kind, and in the limits within which we are necessarily confined. To mention those substances recently introduced into dyeing, the utility of which is not confirmed by extensive practice, would be injudicious, and tend to lead the young dyer astray; those, however, who have leisure and inclination, and are, besides, able to run the risk of the failure of new processes, may, and no doubt will, make experiments with them by which our art must be eventually served and improved.
