The flush upon the cheek is only a token of the same fact within; every organ is congested. The brain has been examined under such circumstances, and "looked as if injected with vermilion ... the membrane covering both brains resembling a delicate web of coagulated red blood, so tensely were its fine vessels engorged."
The immediate organs of sense, as the retina of the eye, probably consist of moving fibrils, with a power of contraction similar to that of the larger muscles above described. The cellular membrane consists of cells, which resemble those of a sponge, communicating with each other, and connecting together all the other parts of the body.
We found at the inner corner of our eye a small, curious, semi-lunar fold that is of no use whatever to us, and is only interesting as the last relic of the nictitating membrane, the third, inner eye-lid that had a distinct physiological purpose in the ancient sharks, and still has in many of the Amniotes.
When fully distended, they are so numerous as in appearance to constitute almost the whole lung. They are of various sizes, from the twentieth to the hundredth of an inch in diameter, and are lined with an exceedingly fine, thin membrane, on which the minute capillary branches of the pulmonary arteries and veins are copiously ramified.
In one of the cases the larvae entered the drum-cavity through a rupture in the tympanic membrane. In both cases the maggots were removed by forceps. The creature was killed by a mercuric-chlorid solution, and removed with a probe. There is a common superstition that centipedes have the faculty of entering the ear and penetrating the brain, causing death.
The body would then emerge above the clasped leaves, and a higher twig would be caught by the teeth; and so on successively, until they had got as high as they wished, when they proceeded to hook themselves to a twig and assume the inverted position side by side; after which, one drew in its head and went to sleep, while the other began licking the end of its wing, where my finger and thumb had pressed the delicate membrane.
The blood goes to the lungs where it irritates the delicate mucous membrane. In self-protection it begins to secrete an excess of mucus and if the irritation is great enough, pus. The various bacteria are incidental. The tubercular bacillus is never able to gain a foothold in healthy lungs, but after degeneration of lung-tissue has taken place the lungs furnish a splendid home for this bacillus.
The heart is one of the greatest sufferers from alcohol. Quoting again from Dr. Richardson: "The membranous structures which envelope and line the organ are changed in quality, are thickened, rendered cartilaginous and even calcareous or bony. Then the valves, which are made up of folds of membrane, lose their suppleness, and what is called valvular disease is permanently established.
Lyons says that it is one of the most loathsome diseases that comes under the observation of medical men. He describes the disease as "essentially a scrofulous inflammation of the Schneiderian membrane, ... which finally attacks the bones." Flies deposit their ova in the nasal discharges, and from their infection maggots eventually arise.
It should then be reduced in a small coffee mill, the flour and middlings separated by sifting and the bran repassed through a machine that will crush it without breaking it; then dress it again, and repeat the operation six times at least. The bran now obtained is composed of the embryous membrane, a little flour adhering to it, and some traces of the teguments Nos. 2, 3, 4, and 5.
