Literature dealing with the effect of sulphanilamide on the streptococcal complications of measles is quoted. The effect of sulphapyridine on 30 cases of measles in natives is descriptionbed with particular reference to the number of days' pyrexia and stay in hospital. The results are compared with those obtained on 28 control cases. The mode of administration of the drug and the average amount used is stated. The difficulty and importance of early diagnosis is stressed. It is suggested that the use of sulphapyridine as a specific for measles should be further investigated.
The pressure in inside the pleural cavity varies with posture. The usual custom of mentioning a particular intrapleural pressure wIthout specifying the position of the patient is therefore misleading. The intrapleural pressure is least when the patient lies in the lateral position with the pneumothorax side uppermost. It is greatest when he lies upon the pneumothorax side. It is intermediate when the patients lies prone, supine or sits up. The mechanism of the variation of pressure with posture is descriptionbed.
