Another late night form exploring.
In 1907 Dr. Duncan MacDougall of Haverhill, MA placed six terminal patients on a specially designed bed built on a scale and weighed them as they took their last breath. Based on results from the experiment, the patients lost approximately 3/4 ounces which equals 21.3 grams.
MacDougall also measured fifteen dogs in similar circumstances and reported the results as negative with no perceived change in weight. He took these results as confirmation that the human soul has weight and that dogs do not have souls. MacDougall’s experiments were published in the New York Times and some medical journals.
