EFFECT OF ALCOHOL ON THE MEMBRANES  The parts which first suffer from alcohol are those expansions of the body which the anatomists call the membranes. "The skin is a membranous envelope. Through the whole of the alimentary surface, from the lips downward, and through the bronchial passages to their minutest ramifications, extends the mucous membrane. The lungs, the heart, the liver, the kidneys are folded in delicate membranes, which can be stripped easily from these parts. If you take a portion of bone, you will find it easy to strip off from it a membranous sheath or covering; if you examine a joint, you will find both the head and the socket lined with membranes. The whole of the intestines are enveloped in a fine membrane called  peritoneum . All the muscles are enveloped in membranes, and the fasciculi, or bundles and fibres of muscles, have their membranous sheathing. The brain and spinal cord are enveloped in three membranes; one nearest to themselves, a pure v...

EFFECT OF ALCOHOL ON THE BLOOD.   Dr. Richardson, in his lectures on alcohol, given both in England and America, speaking of the action of this substance on the blood after passing from the stomach, says:  "Suppose, then, a certain measure of alcohol be taken into the stomach, it will be absorbed there, but, previous to absorption, it will have to undergo a proper degree of dilution with water, for there is this peculiarity respecting alcohol when it is separated by an animal membrane from a watery fluid like the blood, that it will not pass through the membrane until it has become charged, to a given point of dilution, with water. It is itself, in fact,  so greedy for water, it will pick it up from watery textures, and deprive them of it until, by its saturation, its power of reception is exhausted , after which it will diffuse into the current of circulating fluid."  It is this power of absorbing water from every texture with which alcoholic sp...
