Abstract
The use of SO2 in the nebulized form is an efficacious method for producing bronchial secretions in patients who have pulmonary lesions without cough or sputum. No serious deleterious side-effects from its use were encountered. It is almost universally effective in cough and sputum production. The simplicity of the procedure opens up avenues of approach in the survey of individuals in industry and may lead to its application in clinic and office practice, much as the vaginal smear is now employed.
