comes into such contact with the air we breathe, that the oxygen gas in the air is freely absorbed by the little corpuscles, while the carbonic acid is given up into the air-passages of the lungs, and is thrown off with every breath we throw out. In this process the blood changes in color. It comes into the lungs of a dark color; it goes out of them a bright red.***** The parts of the blood on which alcohol acts injuriously are the corpuscles and the fibrine. The red corpuscles are most distinctly affected. They undergo a peculiar process of shrinking from extraction of water from them. They also lose some of their power to absorb oxygen from the air. In confirmed spirit-drinkers the face and hands are often seen of dark mottled color, and in very bad specimens of the kind, the face is sometimes seen to be quite dark. This is because the blood cannot take up the vital air in the natural degree. *****
"If anything whatever interferes with the proper reception of oxygen by the blood, the blood is not properly oxidized, the animal warmth is not sufficiently maintained, and life is reduced in activity. If for a brief interval of time the process of breathing is stopped in a living person, we see quickly developed the signs of difficulty, and we say the person is being suffocated. We observe that the face becomes dark, the lips blue, the surface cold. Should the process of arrest or stoppage of the breathing be long continued the person will become unconscious, will stagger and fall, and should relief not be at hand, he will in a very few minutes die.
"I found by experiment that in presence of alcohol in blood the process of absorption of oxygen was directly checked, and that even so minute a quantity as one part of alcohol in five hundred of blood proved an obstacle to the perfect reception of oxygen by the blood. The corpuscles are reduced in size, when large quantities of alcohol are taken, and become irregular in shape."
