The author's experience has shown the necessity for recognised methods of examination and authentic results, which may be looked upon as a basis in the disputes which constantly occur in regard to the purity and strength of these materials. In the following pages an account of the various limes will be found, the importance of which alone is very far reaching. By the detection of improper ingredients, and the establishment of a proper specification, the author was enabled on one occasion to remedy very grave defects, and to effect a saving to one firm alone of no less a sum than £2000 per annum I The various kinds of clay and sand, and their substitutes, are also fully dealt with.
