- We have now pointed out the existence of two distinct orders of mineral masses, the aqueous and the volcanic: but if we examine a large portion of a continent, especially if it contain within it a lofty mountain range, we rarely fail to discover two other classes of rocks, very distinct from either of those above alluded to, and which we can neither assimilate to deposits such as are now accumulated in lakes or seas, nor to those generated by ordinary volcanic action. - "The Student's Elements of Geology", Sir Charles Lyell.
- When we pass from the agency termed igneous, to aqueous and atmospheric agencies, we see the like ever- growing complications of effects. - "Essays: Scientific, Political, & Speculative, Vol. I", Herbert Spencer.
- It is indeed a purely aqueous exhibition, in which architecture and sculpture have nothing to do. - "A Bibliographical, Antiquarian and Picturesque Tour in France and Germany, Volume Two", Thomas Frognall Dibdin.
