NORMAN CHEVERS, in his work on Diseases in India, records that early in its history, Bengal became notorious for asthma. Also that the reason why Clive was given command of the relieving forces, proceeding from Madras to Calcutta in 1756 after the Black Hole catastrophe, was because his senior officer, being subject to asthma, was considered unfit for service in Bengal. Asthma is still very prevalent in Calcutta. I have obtained most promising results in a number of cases by vaccine treatment on very simple lines. I would like to put my experience on record.
