“But I am very far from thinking that the causticity of quick-lime is at all owing to this circumstance.”

“It explains at once causticity and non-causticity, transparency and opacity, colour and the absence of colours.”

“He now knew to what the causticity of alkalies is owing, and how to induce it, or remove it, at pleasure.”

“Production is potentially dangerous, as you need to heat volatile methanol with caustics.”

“In severe cases of ichthyosis hystrix it may be necessary, also, to employ caustics or the knife.”

“Nevertheless, this elucidation of the generic discontinuous change has shed light upon many optical phenomena where caustics and diffraction occur.”
