"Frog Hoppers are ranked under the homopterous sub-order of insects. The name of frog hopper refers partly to the form of their body, partly to their leaping powers, which are great; this power arises from the length of their hind legs. The larva of these insects, which resembles the parent in most respects except in the want of wings, envelops itself in a froth resembling human spittle. All must have often observed ths on plants."&mdash;(Charles Leonard-Stuart, 1911)

"Victoria Regia, named by Lindley after Queen Victoria, is the most magnificent of all known water lilies, and comes from a region in which it had been supposed that no Nymph&aelig;ace&aelig; occurred. It was first discovered by the botanist H&aelig;nke in 1801; Bonbigny, in 1828, sent home specimens to Paris; others also subsequently saw it growing, but it excited no attention till in 1837, Sir Robert Schomburgk found it in the Berbice river in British Guiana. The rootstock is thick and fleshy, the leaf-stalks prickly, the leaf peltate, its margin circular, its diameter from 6 to 12 feet, the edge so turned up as to make the leaves floating in tranquil water look like a number of large trays.

"Tea is the dried leaf of an evergreen shrub of the natural order Ternstœmiaceæ. It includes the China plant, and the indigenous Assam plant. At one time it was supposed that two Chinese species were grown of which one furnished the black tea and the other the green tea of commerce, but further research has shown that these species cannot be maintained. Whether the tea shrub is indigenous in China and Japan is a doubtful question. The fact has been historically established that the culture of tea existed in China in the 4th century, and in Japan in the 9th century, and from these countries it was exclusively obtained for any other part of the globe till the time of the present generation. The discovery of the indigenous plant in the forest country of Upper Assam was made in 1834, and since 1840 its cultivation there has taken very firm root."—(Charles Leonard-Stuart, 1911)

"Speculum, a mirror, a looking-glass. The looking-glasses of the ancients were usually made of metal, at first of a composition of tin and copper, but afterwards more frequently of silver. The ancients seem to have had glass mirrors also like ours, consisting of a glass plate covered at the back with a thin leaf of metal. They were manufactured as early as the time of Pliny at the celebrated glass-houses at Sidon, but they must have been inferior to those of metal, since they never came into general use, and are never mentioned by ancient writers among costly pieces of furniture, whereas metal mirrors frequently are. Looking-glasses were generally small, and such as could by carried in the hand. Instead of their being fixed so as to be hung against the wall or to stand upon the table or floor, they were generally held by female slaves before their mistresses when dressing. The general form of looking-glasses is shown in the following wood-cut." &mdash; Smith, 1873
