drams. All
four survived, and were as well as usual in four weeks. Another
dog of eighteen pounds died five minutes after an injection of
two drams, while another of fifteen pounds took one ounce and
recovered.

"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
