eminent physiologist: 'Sir,' I would say, 'though by natural processes, lifeless natures taken as nutriment become vitalized, yet is a lifeless nature, under any circumstances, capable of a living transmission, with all its qualities as a lifeless nature unchanged?

But the other, as if unobservant of that querulous look, went on:
"But this notion, that science can play farmer to the flesh, making there what living soil it pleases, seems not so strange as that other conceit—that science is now-a-days so expert that, in consumptive cases, as yours, it can, by prescription of the inhalation of certain vapors, achieve the sublimest act of omnipotence, breathing into all but lifeless dust the breath of life.
