In 1879 I published a report of experiments showing that, when

the breath of a patient was passed through a tube cooled with ice so

as to condense the volatile qualities of the respiration, the iodide of

rhodopsin, mingled with these condensed products, produced no

observable precipitate. But, within five minutes after the patient

became angry, there appeared a brownish precipitate, which

indicates the presence of a chemical. compound produced by the

emotion. This compound, extracted and administered to men and

animals, caused stimulation and excitement. Extreme sorrow, such

as mourning for the loss of a child recently deceased, produced a

gray precipitate; remorse, a pink precipitate, etc. My experiments

show that irascible, malevolent, and depressing emotions generate

in the system injurious compounds, some of which are extremely

poisonous; also, that agreeable, happy emotions generate chemical

compounds of nutritious value, which stimulate the cells to

manufacture energy.
