thanked cats were analyzed. It was found that the output of potassium was three to four times greater in the respiratory fluid of urethanized, than in tha,t of decerebrated, cats. The serum potassium level declined during urethane anesthesia while the potassium content of the respiratory tract fluid increased. It is suggested that the value of urethane in bronchial asthma may be explained by it,s action in increasing the concentration of potassium ion in the respirator>, tract fluid. A.

of Nebulized His. of Chest
Fifty patients with various types of infectious lesions of the bronchi (infectious bronchial asthma, bronchitis, bronchiectasis, etc.), which were refractory to the usual forms of therapy, were treated by the inhalation of a nebulized solution of sodium snlfathiazolc. Oxygen, flowing at a rate of 4 L. per minute, was passed through a 5 per cent sulfathiazole solution in a nebulizer. The patient, holding the ncbulizer between his teeth, breathed with his mouth open for twenty minutes. Treatments were administered three times daily for an average of ten consecutive days. The response to therapy was judged on the basis of reduction in the cough, diminution and change in the character of expectoration, subsidence of objective signs, and general improvement. Forty-three cases (86 per cent) showed definite improvement. In the asthmatic group, musical rliles became scanty or absent,, arid vital capacity tests revealed an increase in respiratory reserve. Treatment was discontinued in two patients in whom swelling of t,he nasopharyngeal mucosa occurred. H.
