The practice of allergy has developed into a major medical science within the past twenty years. It now seems advisable to analyze the results obtained in the treatment of the most important allergic condition, bronchial asthma.

No case was included unless the period of at least one year had elapsed since treatment was started, and this period of observation ranged up to twenty years. Cases from private practice were utilized in both studies because the cooperation of this group is greatly superior to and the information obtained much more reliable than that which can be secured in the clinic.
