In response to the chemical consumption of lecithin a new oil flows down the axis cylinders of the nerve fibrils, which are arranged like lamp wicks. The duration of the flow of this oil is, on the average, about eighteen hours. When the cerebro-spinal nerves refuse longer to perform their function, fatigue and sleep ensue, and the current of blood leaves the brain and seeks the intestines. While the cerebro-spinal system rests, the sympathetic system takes up its task of directing the renewal of tissue and supplying the nerve sheaths through the lymph vessels, which draw their material from the digestive canal, with a new supply of phosphatic oil. Thus the brain and spinal nervous system are prepared for another day's work. For the fulfillment of these processes, the magnetic blood current forms the intermediary.
The presence of formic and acetic acid supplies the blood with fresh electricity to stimulate the nerves. "Under normal conditions," says Julius Hensel, "this function is assigned to the spleen. This organ takes the part of a rejuvenating influence in the body in the manner of a relay station, and does so by virtue of an invisible but significant device. In every other region of the body the hairlike terminals of the arteries which branch out from the heart merge directly in the tiny tubes (capillaries) of the veins, which lead back to the heart again: in the spleen this is not the case. Here rather the arteries end suddenly when they have diminished to a diameter of one one-hundred-and-fortieth of an inch and end in a bulb (the Malpighian bodies). Under such circumstances the sudden stoppage, particularly the impact of the magnetic blood stream against the membrane of a Malpighian body, exemplifies the physical law of the induction of electricity, in accordance with which the blood that enters the spleen is changed into plasma and exudes through the membrane of the Malpighian bodies. The event indicates some fluidity of the red blood cells, which is a change effected in the body by the impact of electric sparks, and one which electrical therapy also brings about locally to prevent increase in the solid constituents of the blood."
The numerous Malpighian bodies in the spleen act as so many electrical conductors, and the product of their electrical activity is found in the formic and acetic acid of the fluid plasma which filters through the Malpighian corpuscles and supplies the acid tissue of the spleen (pulpa splenica). These acids are the electrolytic division products of lecithin. In the splenic pulp arise the capillaries of the splenic veins whose acid blood is carried directly to the liver, where certain cells formed like galvanic elements possess the property, through the electrical action of formic and acetic acid, of extracting from blood albumen the opposite of acids, namely, alkaline bile. The normal functioning of the liver, therefore, is dependent upon that of the spleen, and since the bile produced by the liver goes to aid the digestive activity of the duodenum, disturbance of digestion must result when the quality of the bile is inferior.
One of the substances contained in bile, lecithin, is of wide importance. When it was referred to a moment ago, I spoke only of its individual chemical nature as a fat in combination with ammonium phosphate, as by so doing I avoided error in connection with its apparently complicated formula, which includes glycerophosphoric acid, trimethylamin, palmitic and stearic acids. As it is a fatty substance, the only question that arises, is, what does it contain besides fat? This may be answered by a process of substraction:
2 (C21 H42 O4) C42 H84 O8 which represents tallow or stearate of glycerine. Lecithin, C42 H84 O9 NP, differs from this only by a larger amount of NP. The significance of this difference becomes clear when two atoms of water are added. Then ammonium phosphate, PO3 H4, N is formed. The two atoms of water needed for the condensation of the ammonium phosphate from the stearate are obtained by separating them away from two of glycerine.
The bile contains lecithin in a partially oxidized form. The chemical "remainders" are biliverdin and cholesterin. The latter when normal has, as you know, the power to neutralize snake venoms and other poisons, and thus acts as a natural anti-toxin. In addition, the bile contains combinations of stearine with gelatine and with carbonate and sulphate of sodium, which theoretical chemists believe are twin compounds of glycocholate and taurocholate. These fatty compounds depend upon stearine partly oxidized, that is deprived of a certain number of atoms of hydrogen.
As the compounds of fatty acids with ammoniacal blood gelatine and sodium carbonate, the ingredients of the bile also, develop into a peculiar soap. In the economy of the body the bile acts as a soap. When it is discharged into the duodenum, it changes the fats into so fine an emulsion (chyle) that the microscopically fine drops of fat may be drawn into the orifices of the lymph canals and conveyed to the circulatory system, and the cleavage products of albumen produced by gastric digestion, the peptones (leucin and tyrosin) are carried along with them for the renewal of tissue cells consumed in respiration.
If a soda soap is requisite for the purpose just stated, it follows that soda in the food is essential, as otherwise the supply of soda in the blood albumen cannot be renewed, and the bile cannot get its necessary supply of soda from blood albumen devoid of soda. Consequently, the entire nutritive process is dependent upon bile, and the bile cannot properly perform its function if denied soda.
In addition to carbonates of sodium, especially the hydrocarbonate known as glycolate, the bile apparently contains ammonium sulphate combined with hydrocarbon (taurin); but this results from the transposition of sodium sulphate and gelatine. Gelatine contains six atoms of hydrocarbon joined with two of ammonium carbonate, a group which is separable by chemical action into five of carburetted hydrogen with ammonium carbonate (leucin or gelatine milk), C5 H10, CO2, NH3, and into one of carburetted hydrogen with ammonium carbonate (glycin or gelatine sugar), CH2, CO2, NH3. This latter substance, gelatine sugar, is not produced in the liver, as it exists already in the blood gelatine. In an isolated condition it has the property, in virtue of its ammoniacal acids and its carbonic acid bases and, therefore, of both combined, its salts, of producing chemical fixation. This property is conveyed to the undivided blood gelatine in which the gelatine sugar is contained intramolecularly.
Since normal blood albumen is inconceivable without sulphur it is absolutely essential, in accordance with our knowledge of the constituents of the bile and their origin, that our nutriment should contain a sufficiency of sodium sulphate, if normal blood serum is to be produced. The use of pepsin for this purpose cannot serve nature's purpose, as it contains neither sodium carbonate nor sodium sulphate. Our blood must be given a fresh and sufficient supply of sodium carbonate and sodium sulphate via our food, if it is to produce normal bile and supply the requisites of normal nutrition.
