Belinovski gives an account of a hip-joint amputation and extirpation of a fatty caudal extremity, the only one he had ever observed.
Before the Berlin Anthropological Society there were presented two adult male Papuans, in good health and spirits, who had been brought from New Guinea; their coccygeal bones projected 1 1/2 inches.

Oliver Wendell Holmes in the Atlantic Monthly, June, 1890, says that he saw in London a photograph of a boy with a considerable tail.

The "Moi Boy" was a lad of twelve, who was found in Cochin China, with a tail a foot long which was simply a mass of flesh.

Miller tells of a West Point student who had an elongation of the coccyx, forming a protuberance which bulged very visibly under the skin.

Exercise at the riding school always gave him great distress, and the protuberance would often chafe until the skin was broken, the blood trickling into his boots.
Bartels presents a very complete article in which he describes 21 persons born with tails, most of the tails being merely fleshy protuberances.
