Sulcus

“ On the inner surface of the frontal the "sulcus longitudinalis" is feebly and irregularly indicated where the inner table begins to project before being continued into a strongly developed "frontal crest," which terminates at its forward subsidence in a small "foramen cæcum." ”

“ Thus when a preparation of sulphur is administered as a medicine, nature, in her effort to get rid of the sulphur, opens her pores to expel it. This is proved by the resulting perspiration, and by the circumstance that everything in contact with the patient is found, on analysis, to be largely impregnated with the constituents of the medicine;—the well-known fact of all articles of silver about the person, being tarnished, being an illustration of this effect;—in addition to this the stomach is weakened and irritated by the medicine which has been poured into it ”

“ These poisons cause the intestines to act violently in an effort to throw out the offending substances.
Vegetable Sulfur in the Human Body—I have herein mentioned a number of sulfur compounds which are foreign or harmful to animal life. In wonderful contrast to this is the fact that sulfur is an essential constituent of the human body, and in certain complex compounds with nitrogen and other elements, forms the brain, nerves, and many other body-tissues. ”

“ Antidotes and Treatment.—Soluble sulphates (especially magnesic sulphate) have been given largely in both acute and chronic cases; in the acute, it stands to reason that it is well to ensure the presence of plenty of sulphates in the stomach and intestines, in order to form the sparingly soluble lead sulphate, should any residue remain; but to expect this double decomposition to go on in the blood and tissues is not based upon sound observation. ”

“ Oh! yes—I am decidedly a sulphur patient, no doubt I suppose I have taken several pints of that innocent remedy in my time. A number of physicians have given it to me from time to time. Your friend is not its only devotee. Sulphur and nux—nux and sulphur! I believe they cure anything short of a broken heart, or actual imbecility, do they not, doctor? ”

“ Sulphur, sometimes in the form of milk of sulphur, was used; in another, the common flower of sulphur; sometimes acetate of lead, at other times oxide of that metal. In all the chemical change is the same, namely, the solution of the metal entering into the filament by absorption, there unites with sulphur, forming a sulphuret of the material used. Hair is porous; sulphur exists in hair of all colours, but is in excess in red and blonde hair. ”

“ Just as an engine requires a governor to regulate its pace, so the human body requires a controlling factor to ensure definite stability. It is interesting to observe that normal blood contains about twice as many sulphates as phosphates. When there is great scarcity of sodium sulphate in the blood, abnormal growths develop from the phosphatic nerve tissues, and they continue to develop so long as the blood and lymph are deficient in sulphur, particularly the sulphates. This is, I believe, the genesis of polyps, tumors and cancers. ”

“ The greater number of physiological and hygienic experts agree that the fumes of burning sulfur, commonly known as sulfurous acid, are injurious to health. It has been shown by researches in the Bureau of Chemistry that sulfurous acid or sulfites have a specific influence upon the red corpuscles of the blood, tending to diminish them very largely in relative numbers. ”

“ But sulphuric acid, like all the concentrated acids and caloric, produces the same effect upon all animal substances, even after death; it is the horny hardening. When the absorbents, particularly the thoracic duct are touched with the point of a scalpel, no contraction follows. If they are capable of contracting upon themselves, it appears that it is when they cease to be distended, and not when they are irritated; and that it is consequently by their contractility of texture. ”

“ There are several sulfurous springs—one saline, another strongly impregnated with sulphuretted hydrogen—in great repute for gout, rheumatism, skin diseases and affections of the liver and kidneys. The well of effervescent chalybeate water is largely resorted to for anaemia and as a tonic. ”

“ Her physician was sent for in alarm and haste. On his arrival he laughed immoderately and said, “Madame, you are not ill, you are a chemical product. You are no longer a woman, but you are a ‘sulfid.’ It is not now a question of medical treatment, but a simple chemical reaction. I shall subject you to a bath of sulfuric acid diluted with water. The acid will have the honor of combining with you; it will take up the sulfur, the metal will produce a ‘sulfurate,’ and we shall find [59] as a ‘precipitate’ a very pretty woman.” ”

“ But the Quantity of Sulphur we obtain’d by Digestion was much too great to have been latent in the Oyl of Vitriol. And that Vitriolate Spirits are not necessary to the Constitution of such a Sulphur as ours, I could easily manifest, if I would acquaint you with the several wayes by which I have obtain’d, though not in such plenty, a Sulphur of Antimony, colour’d and combustible like common Brimstone. ”

“ While so much doubt has been cast on the action of the sulphur of these waters, it may be admitted that the sulphides are probably decomposed in the stomach and sulphuretted hydrogen generated. That gas is probably a slight stimulant to the intestine. What sulphuretted hydrogen reaches the blood is eliminated by the lungs. There seems to be no doubt that the gas is absorbed in small quantities by the skin.
It is in sulphur waters chiefly that glairin and baregin occur. This peculiar organic substance has been found both in American and in European springs. ”

“ Irregular masses of sulphur are often found where sulphide minerals, like pyrite or galena have been decomposed in such a way as to leave the sulphur behind. The extensive beds of sulphur are usually associated with gypsum, and are thought to be the result of water, containing bituminous matter, so acting on gypsum as to remove the calcium and oxygen as lime, and leave the sulphur. Finally many waters carry sulphates in solution, from which the sulphur may be 167 precipitated by certain sulphur bacteria, making thus incrustations on the bottom of ponds or lakes. ”

“ When the sulphur has been completely burnt off, the residue (which consists chiefly of sand) is collected and weighed. In a separate portion the moisture and arsenic are determined; the amounts of [Pg 368] these are deducted from the loss in the first experiment. The difference, multiplied by 10, gives the percentage of sulphur.
WET METHODS.
Solution.—All sulphates, excepting those of lead, barium, strontium, and lime, are soluble in water or dilute acid. All sulphides, except cinnabar, are converted into sulphates by the action of nitric acid at a gentle heat ”

“ For the common Sulphur, whether of an impure, or pure Metal whilst conjoyned with its own body, mixt with Salt Peter only in the burning heat of Fire is easily changed into a most hard and most fixed Earth, but this Earth is thenceforth by the Aire easily changed into a most limpid Water: and this Water afterward, by a more strong Fire, according to the Nature of the Metallick pure or impure Sulphur mixt is converted into Glass, admirably Well tinged with various Colours. ”

“ Paracelsus maintained that the human body is composed of salt, sulphur, and mercury, and that in these “three first substances,” as he calls them, health and disease consist: that the mercury, in proportion to its volatility, produces tremors, mortifications in the ligaments, madness, phrensy, and delirium, and that fevers, phlegmons, and the jaundice, are the offspring of the sulphureous principle, while he supposed that the cholic, stone, gravel, gout, and sciatica derive their origin from salt. ”

“ Ten grains of the crystals of sulphuretted sulphite, when treated with liquid oxymuriate of lime to saturation, require 2+ grains of oxygen and yield 8 grains of sulphate of barytes, together with an excess of sulphuric acid which with muriate of barytes gives 8 grains more of sulphate. From these facts it may be concluded that the sulphuretted sulphite consists of one atom barytes, 2 sulphur, 2 oxygen, and 2 water, and that 4 more of oxygen are derived from the oxymuriatic acid to convert the sulphurous oxide into sulphuric acid. ”

“ From the decomposition of the sulphate of iron which takes place, a vast quantity of sulphuric acid must be generated, which, reacting on the different bases of magnesia, lime, etc., contained in the strata, forms those sulphates so prevalent in the higher or pyritous beds of the Lias; the oxide of iron being at the same time more or less completely separated. By this means the mineral waters, which are probably mere brine-springs at the greatest depths, acquire additional medicinal qualities as they ascend to the places whence they flow. ”

“ Uriage has a very large amount of chloride of sodium in its springs. Cold sulphur waters are on the whole more used in liver and indigestion than warm ones. The general effects of warm sulphur Waters differ so little at the various baths as to make it difficult to mention anything special to particular localities. ”

“ It needs no further explanation to realize that sulphur and phosphorus, by the way in which levity and gravity are interlinked in each of them, are representatives of these very qualities 'moist' and 'dry'. As such they are universally active bearers of these qualities in every realm of nature's varied activities, as their physical presence in such cases confirms. Consequently, sulphur is found in the protein-substances of the human body wherever they are bearers of metabolic processes, while the presence of phosphorus is characteristic of the nerves and bones. ”

“ When the animal dies, and the vital forces give way to chemical affinities, when the phosphorus and the rest take their departure, the sulphur, too, finds itself occupation in new fields of duty.
Chlorine and sodium, two more of the elements of animal structures, produce, in combination, common salt,—without which our food would be so insipid, that we have the best evidence of its being a necessary article of diet. The body has many uses for salt. ”

“ On killing it and opening the body, the thoracic duct was found to be full. A considerable quantity of chyle was collected from it. Now, as it is asserted by some, that fat passes undissolved into the chyle, and as I believe that sulphur is digested in the neighbourhood of the bile duct, this chyle was chosen for analysis in preference to blood, as more likely to contain any insoluble sulphur. Besides, the blood would be less satisfactory, on account of the large quantity of albumen and fibrine contained in it, both of them also containing sulphur. ”

“ Sulphur is now generally regarded as emanating from the stage of intermittent lethargy of a volcano, and the sulphides of iron, copper, arsenic, zinc, selenium, etc., fall in the same category as sulphur; they are secondary, not primary, formations. In the stage further off we have the host of sulphates produced by the oxidation of the sulphur into sulphuric acid, and its subsequent reaction on the metals and earths with which it becomes associated. ”

“ In the early stages of mange, flowers of sulphur mixed in vaseline, and rubbed in the coat of the cat, is efficacious, giving sulphur in the milk, the water, and on the food of the patient; also give vegetable diet.
Another remedy: give a teaspoonful of castor oil; next day give raw meat, dusted over with flowers of sulphur. [153] Also give sulphur in milk. If there are any sore places, bathe with lotion made from camphorated oil in which some sulphur is mixed. Oil, 2 oz.; camphor, 1⁄4 oz.; sulphur, a teaspoonful. ”

“ Sul′phūretted, having sulphur in combination; Sulphū′ric, pertaining to, or obtained from, sulphur: denoting a certain well-known strong acid, formerly called oil of vitriol; Sul′phūrous, pertaining to, resembling, or containing sulphur: denoting the pungent acid given out when sulphur is burned in air; Sul′phury, partaking of the qualities of sulphur.—Sulphuretted hydrogen, a compound of sulphur and hydrogen, stinking and noxious; Sulphurous acid, an acid formed by one equivalent of sulphur combined with two of oxygen. [L. sulphur; said to be conn. with Sans. çulvāri.] ”

“ Fourscore horses may be loaded in an hour’s time, each horse carrying 250 lbs. weight. The best veins of sulphur are known by a kind of bank or rising in the ground, which is cracked in the middle. From hence a thick vapour issues, and a greater heat is felt than in any other part. These are the places they choose for digging, and after removing a layer or two of earth, they come to the sulphur, which they find best just under the rising of the ground, when it (the sulphur) looks just like sugar candy. ”

“ Its usual form of occurrence is in combination with the metals to form sulfids, or with oxygen and a metal to form sulfates. Sulfur and iron combine to form iron pyrites or iron disulfid (FeS2) , while sulfur, oxygen, and calcium are found in gypsum, an important fertilizing compound.
Sulfur plays an important part in the nourishment of plants, being found in them both as sulfuric acid and in organic compounds. Methods for estimating the sulfur in both forms will be found in another part of this manual.
