Scientific American Supplement, No. 717, September 28, 1889 Tyndall tells us that each drop of water sheathes electric power sufficient to charge 100,000 Leyden jars and blow the Houses of Parliament to atoms. The Investment of Influence A Study of Social Sympathy and Service This could not well be otherwise; for beyond a contrivance like your Leyden jar, for collecting "air electricity," no means of collecting, still less concentrating, electricity of any kind then existed. Another World Fragments from the Star City of Montalluyah This thought-form may not inaptly be compared to a Leyden jar, the coating of living essence being symbolised by the jar, and the thought energy by the charge of electricity. Thought-Forms Each disk revolves between two metallic rings, c, provided with points that attract and collect in Leyden jars, D, the electricity produced by the friction. Scientific American Supplement, No. 441, June 14, 1884. You charge a Leyden jar and let it discharge; vibration follows and light is excited.

Cyclopedia of Telephony & Telegraphy Vol. 1 A General Reference Work on Telephony, etc. etc. If a small Leyden jar be converted into that form of apparatus usually known by the name of the electric well, it will illustrate this action very completely. Experimental Researches in Electricity, Volume 1 In this case the vacuum bulb is charged from Leyden jars which, in their turn, are excited by an induction coil. McClure's Magazine, Vol. 6, No. 5, April, 1896 Why is an arrangement of several Leyden jars called an electrical battery? The Mirror of Literature, Amusement, and Instruction Volume 17, No. 479, March 5, 1831 A luminous band excited in a bulb by repeated discharges of a Leyden jar must possess rigidity, and if deformed and suddenly released should vibrate. Experiments with Alternate Currents of High Potential and High Frequency On the other hand, Leyden jars with tinfoil coatings showed considerable absorption, and this he thought due to want of close contact between the foil and the glass. Scientific American Supplement, No. 795, March 28, 1891 The other four helices were similarly arranged, but their ends connected with a Leyden jar. Experimental Researches in Electricity, Volume 1 The next step was to bring more energy into play, still using Leyden jars; and for this purpose Dr. Morton placed within the circuit between the jars a Tesla oscillating coil.

The Boy Mechanic: Volume 1 700 Things for Boys to Do It is employed for discharging a Leyden jar or an electrical battery. The Gutenberg Webster's Unabridged Dictionary Section D and E Marconi and his assistants ultimately solved the problem by modifying Lodge's syntonic Leyden jar tuned circuit. The Dawn of Amateur Radio in the U.K. and Greece: a personal view Then the brass ball of a charged Leyden jar was used in place of the excited shell-lac to produce induction; but this caused no alteration of the phenomena. Experimental Researches in Electricity, Volume 1 In 1864 he made researches on the heating of the sides of a Leyden jar by the electrical discharge. Heroes of the Telegraph It soon became apparent that the people were charged with Independence doctrines, and, like an electrified Leyden jar, only waited for the touch of a skilful hand to produce the explosion. The Atlantic Monthly, Volume 04, No. 25, November, 1859 We are but forces—bottled up forces—charged Leyden jars. Weighed and Wanting It is needless to say to those who understand a Leyden jar, that nothing of the sort takes place. The Atlantic Monthly, Volume 02, No. 08, June 1858 When a Leyden jar is charged, the particles of the glass are forced into this polarized and constrained condition by the electricity of the charging apparatus. Experimental Researches in Electricity, Volume 1 He cut the wire at the middle, to form a gap which a spark might leap across, and connected its ends to the poles of a Leyden jar filled with electricity. Heroes of the Telegraph Cavallo likewise proposed to use as signals combustible or detonating materials, and to employ as a call the noise made by the discharge of a Leyden jar. Scientific American Supplement, No. 384, May 12, 1883 Other tubes which withstood the passage of the sparks from a Leyden jar, when submitted to the discharge of the coil, exploded after a few seconds when the platinum wires became red-hot. Scientific American Supplement, No. 358, November 11, 1882 "That means that the substitution of the smaller Leyden jar for one of the larger reduced the sending power of this instrument just ten miles," said he. The Sign at Six See Discharge, disruptive Discharge, electric, as balls of fire —— of Leyden jar —— of voltaic battery by hot air —— —— points —— velocity of, in metal, varied —— varieties of —— brush, . Experimental Researches in Electricity, Volume 1 On either side innumerable huge Leyden jars stood ranged in rows, tier topping tier, while above them were columns of Voltaic cells. The Doings of Raffles Haw The upper half of a thin Leyden jar charged is brought into the bell-jar, and held there four or five seconds; it is then found entirely discharged. Scientific American Supplement, No. 275, April 9, 1881 After standing for a few hours in contact with the phosphoric oxide, the gases may be submitted to strong sparks from a Leyden jar without igniting. Scientific American Supplement, No. 358, November 11, 1882 Eldridge said nothing, but replaced the Leyden jar he had but just removed. The Sign at Six He drew a spark from the key with his finger, and finally charged a Leyden jar from this key, and performed all the then known proof-experiments with the lightning drawn from heaven. Steam, Steel and Electricity We cannot discharge at will either a torpedo or a gymnotus, as we discharge at will a Leyden jar or a Voltaic battery. Personal Narrative of Travels to the Equinoctial Regions of America, During the Year 1799-1804 — Volume 2 Is the unconscious any better explanation of phenomena we do not understand than the ‘devil-devil’ by which Australian tribes explain the Leyden jar and its phenomena? Unconscious Memory If the glass has a weak spot, a scratch say, an electric spark is produced at that point and the vessel crumbles, just like a Leyden jar when overcharged. Marvels of Modern Science The insulation of a Leyden jar broke down at this point, and nothing more could be done until it was remedied. The Home of the Blizzard Being the Story of the Australasian Antarctic Expedition, 1911-1914 In his first account of the new apparatus he describes it as 'Leyden jars with a continuously re-established charge'. Man or Matter The action of the fish on the human organs is transmitted and intercepted by the same bodies that transmit and intercept the electrical current of a conductor charged by a Leyden jar, or Voltaic battery. Personal Narrative of Travels to the Equinoctial Regions of America, During the Year 1799-1804 — Volume 2 These tiny sparks from the electrophorus, or the bigger discharges of an electrical machine, can be stored in a simple apparatus called a Leyden jar, which was discovered by accident. The Story of Electricity Then he brought a large phial, tinfoil, rosin and a cat's tail, and in this manner contrived a Leyden jar. Yama: the pit In reading this, my uncle gave a spring as if he had touched a Leyden jar. A Journey to the Interior of the Earth The Leyden jar brought electrical effects of quite unexpected intensity within reach. Man or Matter He invented the lightning rod, discovered the phenomenon of positive and negative electricity, explained the action of the Leyden jar, and was the first American writer on the modern science of political economy. The Quaker Colonies, a chronicle of the proprietors of the Delaware Of late years the principle of induction, which is the secret of the Leyden jar and electrophorus, has been applied in constructing "influence" machines for generating electricity. The Story of Electricity The Leyden jar, in which the mysterious force could be stored, was invented in Holland in 1745 and in Germany almost simultaneously. The Age of Invention : a chronicle of mechanical conquest There was no past and no future for me, and the present felt as though it were sealed up in a Leyden jar. Father and Son: a study of two temperaments These glass capsules are covered with a strip of steel and weighted with a lead base; they're genuine little Leyden jars charged with high–voltage electricity. Twenty Thousand Leagues Under the Sea Nothing like the enthusiasm it created in the philosophic world had been known since the invention of the Leyden jar, more than half a century before. A History of Science — Volume 3 The cloud and earth with air between are analogous to the charged foils of the Leyden jar separated by the glass. The Story of Electricity In June, 1752, he performed the famous experiment with the kite, drawing down electricity from the clouds and charging a Leyden jar from the key at the end of the string. The Age of Invention : a chronicle of mechanical conquest The advent of the Leyden jar, which made it possible to produce strong electrical discharges from a small and comparatively simple device, was followed by more spectacular demonstrations of various kinds all over Europe. A History of Science — Volume 2 The apparatus was virtually a Leyden jar, the two coatings of which were the two spheres, with a thick and variable insulator between them. Faraday as a Discoverer Ursula was seized with a little nervous tremor which made the abbe quiver as though a whole Leyden jar had been discharged at him; he felt moreover a lasting commotion in his heart. Ursula There are, however, batteries known as "secondary," which store the current as the Leyden jar stores up the discharge from an electrical machine. The Story of Electricity After a shower had wetted the string and made it a conductor, he was able to draw sparks from it with a key and to charge a Leyden jar. The Story of Electricity He made also a similar device, more closely resembling the modern Leyden jar, from a thermometer tube partly filled with water and a wire tipped with a ball of lead. A History of Science — Volume 2 Without this reaction of the walls upon the sphere you could no more, according to Faraday, charge it with electricity than you could charge a Leyden jar, if its outer coating were removed. Faraday as a Discoverer Voltaic cells are grouped together in the mode of Leyden jars. The Story of Electricity The Leyden jar is illustrated in figure 9, and consists in general of a glass bottle partly coated inside and out with tinfoil F, and having a brass knob K connecting with its internal coat. The Story of Electricity A cable is virtually a Leyden jar or condenser, and the signal currents in the wire induce opposite currents in the water or earth. The Story of Electricity And so when this professor of Leyden made his discovery, the apparatus came to be called the "Leyden jar," for want of a better name. A History of Science — Volume 2 He might charge a single Leyden jar by twenty turns of his machine, or he might charge a battery of ten jars by the same number of turns. Faraday as a Discoverer CAPACITY—K.—The farad is that capacity of a body, say a Leyden jar or condenser, which a coulomb of electricity will charge to the potential of a volt. The Story of Electricity Leyden jars can be connected together in "batteries," so as to give very powerful effects. The Story of Electricity One of these men dipped his free hand in the water, the other presenting a Leyden jar to a rod suspended on a cork float on the water, both men receiving a shock simultaneously. A History of Science — Volume 2 These studies of the Leyden jar, and the studies of pieces of glass coated with sheet metal, led Franklin to invent his battery, constructed of eleven large glass plates coated with sheets of lead.
