Note 24 — REMARKS
Reading edition
See An Analysis of the Mineral Waters of Tunbridge Wells, by Dr. Scudamore, p. 55.
The application of the sulphuretted hydrogen test requires some precautions in those cases where other metals besides lead may be expected; because silver, quicksilver, tin, copper, and several other metals, are affected by it, as well as lead; but there is no chance of these metals being met with in common water.—See Chemical Tests, third edition, p. 207.
