Note 467 — Chapter XIII
Reading edition
The word is used, designedly but not fraudulently, as combining "observation" and "experiment" to the extent proper to art. Deliberate and after-thought "experiments" in actual life are (except in trivial matters) very risky things; and the Summa Rerum itself is apt to resent them, as, for instance, Mr. Thomas Day and Mr. Felix Graham found in the matter of wife-culture.
