The Japanese Artificially Induced Pearl

Abstract

THE subject of artificial pearl induction, I venture to suggest, affords an excellent example of comparative pathology. Dr. Lyster Jameson's diagram in NATURE of May 26, p. 396, might well pass as an illustration of “pearls” frequently found in the human body. Such “pearls” are commonly seen in papillomata of the skin and at muco-cutaneous areas, but they can also be demonstrated in the tonsils, brain-coverings, thymus and thyroid glands, etc. Those which are epidermal become keratinoid, but others of deeper origin are often calcified.
