Intestinal Quotes

[Mercurial medicines] affect the human constitution in a peculiar manner, taking, so to speak, an iron grasp of all its systems, and penetrating even to the bones, by which they not only change the healthy action of its vessels, and general structure, but greatly impair and destroy its energies; so that their abuse is rarely overcome. When the tone of the stomach, intestines, or nervous system generally, has been once injured by this mineral ... it could seldom be restored.
Quoted in Wooster Beach, A Treatise on Anatomy, Physiology, and Health (1848), 177.

[The heart is] really a fascinating organ. It's about the only organ in the body that you can really witness its function. Doing things. And so on. Some of the other organs you can witness, like the intestines, will have this sort of peristaltic motion. But nothing that can compare with the activity of the human heart.

γῆς ἔντερα
[Literally] Earth’s entrails
[or, entrails of earth, or earth’s intestine, or earth’s guts: earthworm. Often seen out of context as “Earthworms are the intestines of the soil.”].
Aristotle
Contrary to the widespread quote, Webmaster has not yet found a complete sentence in the original Greek translating as “Earthworms are the intestines of the soil.” Webmaster believes Aristotle did not write such a sentence. As far as Webmaster can figure out, Aristotle had no other word for an earthworm than the descriptive two-word phrase above. The word γῆς translates directly as “earth” and ἔντερα as “intestine.” In the context, Aristotle wrote only this, without any other wording for “earthworm,” in De Generatione Animalium (On the Generation of Animals), Book III, 10, 762b. Identified in Arthur Platt, De Generatione Animalium (1910), unpaginated page 23, end of 762b, footnote 1. The Greek phrase is given in William Keith and Chambers Guthrie, A History of Greek Philosophy: Aristotle, an Encounter (1981), Vol. 4, 290, footnote 3. The context, from the Platt translation is: “For all of these [animals], though they have but little blood by nature, are nevertheless sanguinea, and have a heart with blood in it as the origin of the parts; and the so-called ‘entrails of earth’, in which comes into being the body of the eel, have the nature of a scolex.” The translator footnotes that: “These ‘entrails of earth’ are earthworms almost certainly. A. thinks they are spontaneously generated, and develop into eels.” An alternate interpretation is given by A.L. Peck in Generation of Animals, With an English Translation (1943), 361. “The ‘earth’s-guts’ as they are called have the nature of a larva; the body of the eels forms within them.” Peck footnotes: “The ‘earth’s-guts’ are apparently the round-worm Gordius. Webmaster note: These are hairlike, very long, and very thin, nematoid worms that are parasites—not earthworms. Webmaster concludes that gardeners saying “Earthworms are the intestines of the soil” are quoting something that Aristotle did not say, per se, and he did not specifically talk about earthworms as gardeners’ friends conditioning the soil.

[Answering question whether he was tired of life:] Tired! Not so long as there is an undescribed intestinal worm, or the riddle of a fossil bone, or a rhizopod new to me.
Related about Joseph Leidy by Dr. Weir Mitchell, as stated in Richard A. Gregory, Discovery: Or, The Spirit and Service of Science (1916), 17.

But in my opinion we can now be assured sufficiently that no animals, however small they may be, take their origin in putrefaction, but exclusively in procreation… For seeing that animals, from the largest down to the little despised animal, the flea, have animalcules in their semen, seeing also that some of the vessels of the lungs of horses and cows consist of rings and that these rings can occur on the flea's veins, why cannot we come to the conclusion that as well as the male sperm of that large animal the horse and similar animals, and of all manner of little animals, the flea included, is furnished with animalcules (and other intestines, for I have often been astonished when I beheld the numerous vessels in a flea), why, I say should not the male sperm of the smallest animals, smaller than a flea may even the very smallest animalcules have the perfection that we find in a flea.
Letter to Robert Hooke, 12 Nov 1680. In The Collected Letters of Antoni van Leeuwenhoek (1957), Vol. 3, 329.

Having made a sufficient opening to admit my finger into the abdomen, I passed it between the intestines to the spine, and felt the aorta greatly enlarged, and beating with excessive force. By means of my finger nail, I scratched through the peritoneum on the left side of the aorta, and then gradually passed my finger between the aorta and the spine, and again penetrated the peritoneum, on the right side of the aorta. I had now my finger under the artery, and by its side I conveyed the blunt aneurismal needle, armed with a single ligature behind it...
Describing the first ligation of the aorta in 1817 for left femoral aneurysm.

If we reflect that a small creature such as this is provided, not only with external members, but also with intestines and other organs, we have no reason to doubt that a like creature, even if a thousand million times smaller, may already be provided with all its external and internal organs... though they may be hidden from our eyes. For, if we consider the external and internal organs of animalcules which are so small that a thousand million of them together would amount to the size of a coarse grain of sand, it may well be, however incomprehensible and unsearchable it may seem to us, that an animalcule from the male seed of whatever members of the animal kingdom, contains within itself... all the limbs and organs which an animal has when it is born.

Methane is released by bogs, and some 45 million tons of the same gas, it has been calculated, are added to the atmosphere each year by the venting of intestinal gases by cattle and other large animals.

On opening the incubator I experienced one of those rare moments of intense emotion which reward the research worker for all his pains: at first glance I saw that the broth culture, which the night before had been very turbid was perfectly clear: all the bacteria had vanished…as for my agar spread it was devoid of all growth and what caused my emotion was that in a flash I understood: what causes my spots was in fact an invisible microbe, a filterable virus, but a virus parasitic on bacteria. Another thought came to me also, If this is true, the same thing will have probably occurred in the sick man. In his intestine, as in my test-tube, the dysentery bacilli will have dissolved away under the action of their parasite. He should now be cured.
In Allan Chase, Magic Shots: A Human and Scientific Account of the Long and Continuing Struggle to Eradicated Infectious Diseases by Vaccination (1982), 249-250. Also in Allan J. Tobin and Jennie Dusheck, Asking About Life (2005), 206.

Since the stomach gives no obvious external sign of its workings, investigators of gastric movements have hitherto been obliged to confine their studies to pathological subjects or to animals subjected to serious operative interference. Observations made under these necessarily abnormal conditions have yielded a literature which is full of conflicting statements and uncertain results. The only sure conclusion to be drawn from this material is that when the stomach receives food, obscure peristaltic contractions are set going, which in some way churn the food to a liquid chyme and force it into the intestines. How imperfectly this describes the real workings of the stomach will appear from the following account of the actions of the organ studied by a new method. The mixing of a small quantity of subnitrate of bismuth with the food allows not only the contractions of the gastric wall, but also the movements of the gastric contents to be seen with the Röntgen rays in the uninjured animal during normal digestion.
In 'The Movements of the Stomach Studied by Means of the Röntgen Rays,' American Journal of Physiology (1898), 1, 359-360.

Skin is what ya feel at home in.
And without it, furthermore,
Both your liver and abdomen
Would keep falling on the floor.
(And you’d be dressed in your intestine).

The choice of zoology as a main subject [at university] was to follow up my childhood love of nature. … My animal studies never became quite what I had hoped for. We hardly heard of wild beasts and the way they lived in the wilderness. We sliced up intestines and looked at them under the microscope … but their life and function in the environment was ignored in favor of their Latin names. … Was our knowledge of nature superior to, or only different from, that of the eagle-eyed Polynesian islanders, who specialized in appraising nature the way it could best benefit man? I had to think as a scientist now. Not as a Polynesian yet. Knowledge was to be sought independently of its purpose.

The drinking of litharge causes oppression of the stomach, belly and intestines, with intense griping pains;… it suppresses the urine, while the body swells and acquires an unsightly leaden hue.

The question, What is cholera? is left unsolved. Concerning this, the fundamental point, all is darkness and confusion, vague theory, and a vain speculation. Is it a fungus, an insect, a miasm, an electrical disturbance, a deficiency of ozone, a morbid offscouring from the intestinal canal? We know nothing; we are at sea, in a whirlpool of conjecture.
Editorial in Lancet 1 (1853), 393. As quoted in Peter Vinten-Johansen, et al., Cholera, Chloroform, and the Science of Medicine: A Life of John Snow (2003), 116.

When you get up here in space and you go into the weightlessness environment, your body is not sure what really just happened to it. So your stomach, intestines, and that stuff kind of shuts down for a few hours to figure out what is going on and during that timeframe your body is not doing much with your food. After your body figures out that it can handle the new environment, everything cranks back up and your food, stomach and intestines and all start working like normal.
Replying to a Mifflin Middle School students’ question during a school forum held using a downlink with the Discovery Space Shuttle mission (31 Oct 1998).

Carl Sagan Thumbnail In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion. (1987) -- Carl Sagan
