"The symptoms in the dogs were all alike, dyspnea, increasing as the inflammation increased, until the accessory muscles of respiration were called into play. The stethoscope showed that air had great difficulty in entering the bronchi and air vesicles, and showed also the tumultuous beating of the heart in pumping blood through the lung. It was impossible to take the temperatures. Post-mortem examinations showed the lungs dark, congested and solid in some places. The air passages were filled with frothy, bloody mucus, even in the dog that died in five minutes. On section, the lungs were dark, congested, and full of bloody mucus. This shows how acutely sensitive the respiratory passages are to the action of alcohol. On microscopic examination of the lungs, the air tubes and vesicles were found filled with immense numbers of red and white corpuscles and much mucus. The same picture was presented as in a slide from the lungs of a broncho-pneumonic child. "The striking similarity between the two is enough to prove that the pathological condition is the same, and that alcohol has produced a lesion very closely resembling, if not absolutely like, that of broncho-pneumonia in the human subject. This to some extent explains why drunkards attacked by pneumonia succumb more readily than the temperate. The sensitive lung tissue is enveloped in alcohol--flowing through the capillaries of the lung on one side, and exhaled, filling the air vesicles and tubes on the other. The condition must create a state of semi-engorgement or of mild inflammation, similar to the drunkard's red nose, or his engorged gastric mucous membrane. Such a state will reduce the vitality of the pulmonary tissue, and its power of resistance to external influences. Add to this an inflammation such as a pneumonia, and the lungs find themselves unable to stand the pressure." As previous chapters contain much showing the reasons why alcohol is dangerous in pneumonia, space need not be taken here to do more than indicate briefly some points of non-alcoholic treatment. Pneumonia is generally supposed to result from a cold; it is ushered in by the symptoms of a chill, followed by fever, headache, shortness of breath, pain in chest, etc. It sometimes occurs as a complication of typhoid fever and other acute diseases. "It is not a very fatal disease in young and healthy subjects, but in weak children, old persons and habitual drinkers, it is a very fatal malady." _Nature Cure_ recommends a vapor bath immediately upon the appearance of the first symptoms, together with copious drinking of hot lemonade, and a good supply of pure fresh air in the room, together with the application of alternating hot and cold compresses, _and no drugs_.
