The cough is loose; older children produce also a little white foam at the mouth. The pulse is very small, but, as regards the number of beats, stands in no relation to the frequency of the respiration. In extensive oedema the physical investigation gives a less sonorous but never a completely dull percussion-sound. As oedema of the lungs is mostly bilateral, and the dulness not very intense, percussion therefore often furnishes no very satisfactory information concerning the existing alteration of the lungs. Auscultation is of greater importance. Extensively-diffused, moist, sibilant rales are heard over the oedematous places, which the practised ear readily distinguishes, by the coarser and less regular sound, from fine crepitation of pneumonia. They are often drowned by the large sonorous rales produced in the larger bronchi by the accumulation of mucus within them, but these, after a violent cough, momentarily disappear. If a hand is laid upon the chest, it will feel these rhonchi extremely strong, while crepitation usually is not perceived by palpation. It is very difficult to distinguish pneumonia from oedema of the lungs, especially in those acute cases of oedema where it is attended by active fever. The dyspnoea, if possible, is even greater in oedema than in inflammation of the lungs, but the physical examination supplies no characteristic differences; the only symptom that tends to make the existence of oedema tolerably certain is the bilateral appearance of crepitation, while lobar pneumonia very generally is only observed on one side.
