Famous quotes containing the word peculiar:
“The French manner of hunting is gentlemanlike; ours is only for bumpkins and bodies. The poor beasts here are pursued and run down by much greater beasts than themselves; and the true British fox-hunter is most undoubtedly a species appropriated and peculiar to this country, which no other part of the globe produces.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
