This is typical of the "New Inquisition" mindset behind vintage Popular Mechanics:
"Poison gas guards 'health' of art treasures." If only Big Science could gas all the arts, this toxic sentiment suggests. It's an example of why Robert Anton Wilson called Big Science the New Inquistion
. The headline is a variation of the old witch test -- if she sinks, she's not a witch, and if the art survives the poison gas, it's "healthy." Yikes. From 1932.
