A hobby horse (or hobby-horse) is a child's toy horse, particularly popular during the days before cars. Just as children today imitate adults driving cars, so, in former times, children played at riding a wooden hobby-horse made of a straight stick with a small horse's head (of wood or stuffed fabric), and perhaps reins, attached to one end. The bottom end of the stick sometimes had a small wheel or wheels attached.

Chinese structures have nothing durable about them, for perishable wood forms an essential element in their construction, and they were more remarkable for their elegance and slender proportions than for their vast dimensions. The roofs are especially characteristic, the most striking peculiarity being that they are always curved, and have figures on them in high relief, as well as at the corners, from which hang bells, and that they are decorated with all kinds of embellishments, such as gilt dragons, and other fantastic carvings.

Oxalis is the largest genus in the wood sorrel family Oxalidaceae. Of the approximately 900 known species in the Oxalidaceae, 800 belong to Oxalis. Many of the species are known as Wood Sorrel or Woodsorrel. The genus occurs throughout most of the world, except for the polar areas; species diversity is particularly rich in tropical Brazil and Mexico and in South Africa.

In Wollaston's battery, the wooden box was replaced with an earthenware vessel, and a copper plate was bent into a U-shape, with a single plate of zinc placed in the center of the bent copper. The zinc plate was prevented from making contact with the copper by dowels (pieces) of cork or wood. In his single cell design, the U-shaped copper plate was welded to a horizontal handle for lifting the copper and zinc plates out out the electrolyte when the battery was not in use.

An illustration of Bussen's cell.The Grove cell was an early electric primary cell named after its inventor, British chemist William Robert Grove, and consisted of a zinc anode in concentrated sulfuric acid and a platinum cathode in concentrated nitric acid, the two separated by a porous ceramic pot. The Grove cell was the favored power source of the early American telegraph system in the period 1840 - 1860 because it offered a high current output and higher voltage than the earlier Daniell cell (at 1.9 volts and 1.1 volts, respectively).

The cell was set up in a glass, or glazed earthenware, pot. This contained the chromic acid solution, the carbon plate and a porous pot. Inside the porous pot was dilute sulfuric acid, the zinc rod, and a small quantity of mercury. The mercury formed an amalgam with the zinc and this reduced "local action", i.e. unwanted dissolution of the zinc when the cell was not in use.

Georges Leclanché invented and patented in 1866 his battery, the Leclanché cell. It contained a conducting solution (electrolyte) of ammonium chloride, a cathode (positive terminal) of carbon, a depolarizer of manganese dioxide, and an anode (negative terminal) of zinc. The Leclanche battery was essentially a self-contained version of an earth battery, and fairly copied its design.

The Daniell cell (var. sp. Daniel cell), also called the gravity cell or crowfoot cell was invented in 1836 by John Frederic Daniell, who was a British chemist and meteorologist. The Daniell cell was a great improvement over the voltaic pile used in the early days of battery development. The Daniell cell's theoretical voltage is 1.1 volts and the chemical reaction is Zn(s) + Cu2+(aq) → Zn2+(aq) + Cu(s).
