CAUSTICS.
Caustics are substances which have the power of destroying or disorganizing animal structures. By their action they destroy the tissue to which they are applied, and form a crust, which is thrown off by a separation from the parts beneath. Their caustic property may be destroyed by dilution with other substances, to such an extent that they will only irritate or stimulate, and not destroy. Much care is necessary in their employment, and it is not expected that the unprofessional reader will have much to do with them; hence, we have deemed it best not to give a list of these agents.
