I want to congratulate TIME'S editor on its section on Medicine. Statements are always brief and nearly always correct. The issue of July 3 contained much information regarding the ductless glands, nearly all correct, but parathyroid tumors are accompanied by an increase in the parathyroid hormone which abstracts calcium from the bones and so leads to softening and cyst formation. Removing the tumor reduces the amount of parathyroid hormone and allows the bones to regain calcium.
It might interest TIME to know that railroads and industry have been watching developments...
