Use "plutonist" in a sentence
"From these indubitable cases of erosion -- commencing, if necessary, with the small ravines which run down the flanks of the ridges, with their little working navigators at their bottoms -- we can proceed, by almost insensible gradations, to the largest valleys of the Alps; and it would perplex the plutonist to fix upon the point at which fracture begins to play a material part."
"We find, for example, numerous valleys which the most ardent plutonist would not think of ascribing to any other agency than erosion."
