> In 1901, MacDougall weighed six patients while they were in the process of dying from tuberculosis in an old age home. It was relatively easy to determine when death was only a few hours away, at which point the entire bed was placed on an industrial sized scale which was reported to be sensitive to “two-tenths of an ounce”. He took his results (a varying amount of unaccounted-for mass loss in four of the six cases) to support his hypothesis that the ‘soul’ had mass, and when the ‘soul’ departed the body, so did this mass. The determination of the ‘soul’ weighing 21 grams was based on the loss of mass in the first subject at the moment of death.
