" Naturae lapis humanse servire creatus
Stiptica cui virtus permulta probatur inesse ;
Nam palpebrarum super illitus asperitatem
Et visus hebetes, pulsa caligine, sanat."
Professor
Elmer Gates, of the Laboratory of Psychology at Washington, has just
concluded a remarkable series of experiments illustrative of the
physical processes induced even by right and wrong thinking. He has
reduced anger, jealousy, love, grief, and anxiety to chemical formula?.
According to this Professor, every change of the mental state of an
individual is expressed in the secretions of the body. Treated with the
same chemical reagent, the perspiration of an angry man shows one
colour, that of a man in grief another, and so on through a long list
of emotions.
After
condensing the volatile constituents of the breath of his subjects, the
Professor obtained a brownish sediment from anger, a grey sediment from
sorrow, and a pink sediment from remorse. Of the brownish substance the
Professor administered doses to men, and animals. In every case it
produced nervous excitability, or irritability.
In
his experiments with thought conditioned by jealousy, he obtained
another substance from the breath, which he injected into the veins of
a guinea-pig. The pig died in a very few minutes. After concluding from
his various experiments that hate is accompanied by the greatest
expenditure of vital energy, Professor Gates affirms that this passion
precipitates several chemical products. Enough of these would be
deposited during one hour of intense hate, according to him, to cause
