During the past few years we have had an opportunity to observe an unusual form of spontaneous hypoglycemia which, as far as we are aware, has not been previously reported. The patients concerned have all been chronically addicted to alcohol and have been drinkers of denatured alcohol in a form known locally as "smoke."
