In treatment of a disease such as scabies, which is so prevalent and contagious and the cure of which depends on the meticulous observation of the rules of treatment, it is important that the therapeutic measures be simple, short and effective. The ointment used in the so-called Danish method originated in Copenhagen in 1911. It was reported on by Dr. Svend Lomholt in 1920;1 its use was introduced at the Massachusetts General Hospital in 1923,2 and it has been used at that hospital ever since. An important consideration from the clinician's point of view is that the ointment is applied once and left on for twenty-four hours, no further application being necessary. This report is a survey of the results of the use of that preparation during ten of the years since its adoption as the exclusive treatment of scabies in the clinic of the Massachusetts General Hospital.
