There is no RationalWiki without you. We are a small non-profit with no staff – we are hundreds of volunteers who document pseudoscience and crankery around the world every day. We will never allow ads because we must remain independent. We cannot rely on big donors with corresponding big agendas. We are not the largest website around, but we believe we play an important role in defending truth and objectivity.
If everyone who saw this today donated $5, we would meet our goal for 2019.

Harry La Verne Twining

|Fails from the crypt|
Twining is known for his experiments and investigation of the soul in the early 1900s. One of his experiments consisted of setting up a balance with a glass beaker on either side. He positioned a mouse in each beaker and on the balance pan was a solid lump of potassium cyanide. For the experiment Twining put some cyanide by using tweezers into the beaker on the same balance pan. According to Twining within thirty seconds the mouse had died and the balance arm dropped. Twining also experimented with cats and one of his experiments recorded the loss of one hundred milligrams in a kitten at death. According to the paranormal writer Max Heindel the experiments of Twining had proven that animals have a "vital body" that survives death. However scientists (and even Twining later on in his life) have not been convinced by the experiments.
Twining himself in 1915 wrote that his experiments into the nature of the soul revealed it to have a natural basis and had not proven any supernatural soul. He explained that all of his experiments showed a loss of weight due to the natural cause of moisture loss. When Twining replicated his experiments by sealing the beakers there was no weight loss. So Twining himself ascribed the change in weight to loss of moisture.
Twining's views on the experiments can be found in The Physical Theory of the Soul (1915). Skeptic Milbourne Christopher discussed Twining and his experiments in his book Search for the Soul (1979).
