“Some degree of dyspnoea is always present, and is usually progressive, though towards the end in the fatal cases when the mental acuteness is dulled by the increasing asphyxia the patient is not distressed by its presence. In some cases there have been paroxysmal exacerbations of the breathlessness, accompanied by a state of panic, in which the patient struggles wildly and tries to get out of bed in order to gain relief. Cyanosis is another prominent feature throughout the illness. At first it may not be more than duskiness, but in the later stages it becomes very evident. It is only slightly relieved by oxygen; this, no doubt, is partly explained by the difficulty in giving the oxygen efficiently, owing to the patient’s objection to any mouthpiece that fits at all tightly, and partly by the blocked condition of the bronchioles interfering with the absorption of the oxygen. “The condition usually begins with the presence of a moderate number of sharp crepitant râles, often first heard in the region of the root of the lung; these quickly become generalized. In the majority of the cases signs of bronchopneumonia patches can be made out; these are generally situated near the root of the lungs. In a certain number of cases these patches spread and become confluent, giving practically all of the physical signs of a lobar pneumonia. As the disease progresses the air entry is diminished; on listening one is often struck by the small volume of sound heard. The resonance of the lungs may also be lessened. A slight pleuritic rub was heard in a few of our cases, but this was soon masked by the bronchitis signs.” Detailed sputum examination in twenty cases showed the presence of the influenza bacillus in eighteen, and in ten out of these eighteen the organism was isolated by culture. The next most frequent organism found was the pneumococcus, which was present in thirteen cases. The streptococcus was found in five. Abrahams, Hallows, Eyre and French report the same epidemic:
