Frederick Arnold, Popular Science Monthly (1873)
“ I am like some honest citizen who has only got some modest extent of garden-plot, which he feels bound to lay out with flowers, but at the same time he has some yearnings toward homely but esculent vegetables; or, to vary the simile, just as mathematicians have their pure and applied mathematics, so in discussing questions of medical life and science, one desires not only to look at the subject on its abstract and literary side, but to aim at some concrete good. ”
