Dr. Dewar has recorded a remarkable case in the person of a groom advanced in phthisis, with emaciation, cough, sweatings, haemoptysis, etc., and apparently in a hopeless condition, who conducted sulphur-fumigations for cattle (v. p. 242), remaining with them in the sheds "with the most wonderful benefit to his own health: within one week the night-sweats had ceased, his cough abated, and expectoration diminished; he gained weight - nearly two stone in four months: is now dependent for his life on one lung only, or nearly so, but with the exception of being somewhat short-winded, looks nearly as strong and as able for ordinary work as before his illness" (Pamphlet: "On the Application of Sulphurous Acid Gas," 1866). He reports four other cases of "chronic phthisis" equally benefited; and Mr. Pairman corroborates his observations; they deserve careful consideration, but up to the present there has been little further trial of the method.

It was thought that the sulphurous spray would be of great service in the relief of phthisical symptoms, but I have not seen lasting or important results from it, though it facilitates expectoration and lessens laryngeal irritation.
