The photo below shows a human guinea pig, his feet in “ankle boxes,” where drafts of various temperatures, humidity and velocity, are played.

FOR hundreds of years, people have purchased all sorts of mystic devices for the purpose of foretelling their futures, or jim-cracks intended for the location of oil, water and precious metals.
A common form of mystic locating device is a forked witch-hazel twig, commonly called a devining rod which, in the hands of an operator generally called a "bowser," has been used for centuries for the location of water.

Millions of dollars are annually lost to the "short weight" merchants and to those dispensing foodstuffs in "phony" boxes and packages.
WHEN Mr. and Mrs. Buying Public purchase tickets to a show to observe the magician pull rabbits out of a hat, they fully expect to be fooled; they enjoy the trickery even if they are made parties to it; but when this same couple goes to the market to purchase meat at so much a pound, they object strenuously if the man behind the counter slips an 8-ounce sinker into the fowl before he weighs it.
