An intensely yellow acid salt is described, as is also a very unstable colourless salt which could not be examined further owing to its very labile nature.
Biot relates that, when he himself was beginning his career, Laplace introduced him at the Institute for the purpose of explaining his supposed discovery of equations of mixed differences, and afterwards showed him, under a strict pledge of secrecy, the papers, then yellow with age, in which he had long before obtained the same results.
These crocuses of the flower garden are mostly horticultural varieties of C. vernus, C. versicolor and C. aureus (Dutch crocus), the two former yielding the white, purple and striped, and the latter the yellow varieties.
In 1789 Klaproth isolated from pitchblende a yellow oxide which he viewed as the oxide of a new metal, which he named uranium, after the newly discovered planet of Herschel.
Berzelius about 1823 found that the yellow oxide, when treated with excess of sulphuric acid, gave a sulphate not unlike the ferric salt.
He concluded that the uranium salt was Ur 2033S0 3, where Ur 2 0 3, according to his analysis, represents 864 parts of yellow oxide (0 = 16).
Like Fe 2 0 3, the yellow oxide lost 48 parts of oxygen per Ur203 (= 864 parts) as water, while Ur 2 = 816 parts of metal remained.
Peligot's results, though called in question by Berzelius, have been amply confirmed by all subsequent investigators; only now, on theoretical grounds, first set forth by Mendeleeff, we double Peligot's atomic weight, so that U now signifies 240 parts of uranium, while UO 3 stands as the formula of the yellow oxide, and UO 2 as that of Berzelius's metal.
The precipitate, after having been collected and washed, is digested with a warm concentrated solution of ammonium carbonate, which dissolves the uranium as a yellow solution of ammonium uranate, while the hydrated oxide of iron, the alumina, &c., remain.
Dilute sulphuric acid attacks it but slowly; hydrochloric acid, especially if strong, dissolves it readily, with the formation, more immediately, of a hyacinthcoloured solution of U 2 C1 6, which, however, readily absorbs oxygen from the air, with the formation of a green solution of UC1 4, which in its turn gradually passes into one of yellow uranyl salt, U02.
These salts generally resemble the bichromates; they are yellow in colour, insoluble in water, soluble in acids, and decomposed by heat.
Sodium uranate, Na2U207, is used as a pigment for painting on glass and porcelain under the name of uranium yellow.

Stannous bromide, SnBr 2, is a light yellow substance formed from tin and hydrobromic acid.
Stannous iodide, Sn12, forms yellow red needles, and is obtained from potassium iodide and stannous chloride.
Stannic sulphide, SnS 2, is obtained by heating a mixture of tin (or, better, tin amalgam), sulphur and sal-ammoniac in proper proportions in the beautiful form of aurum musivum (mosaic gold) - a solid consisting of golden yellow, metallic lustrous scales, and used chiefly as a yellow "bronze" for plaster-of-Paris statuettes, &c. The yellow precipitate of stannic sulphide obtained by adding sulphuretted hydrogen to a stannic solution readily dissolves in solutions of the alkaline sulphides to form thiostannates of the formula M 2 SnS 31 the free acid, H2SnS3, may be obtained as an almost black powder by drying the yellow precipitate formed when hydrochloric acid is added to a solution of a thiostannate.
Stannous salt solutions yield a brown precipitate of SnS with sulphuretted hydrogen, which is insoluble in cold dilute acids and in real sulphide of ammonium, (NH 4) 2 S; but the yellow, or the colourless reagent on addition of sulphur, dissolves the precipitate as SnS 2 salt.
Stannic salt solutions give a yellow precipitate of SnS 2 with sulphuretted hydrogen, which is insoluble in cold dilute acids but readily soluble in sulphide of ammonium, and is re-precipitated therefrom as SnS2 on acidification.
This plain diaphanous garment, without distinction of colour (white, red or yellow), and with perhaps only an embroidered hem at the top, was worn by the whole nation, princess and peasant, from the IVth to the XVIIIth Dynasties (Erman, Life in Ancient Egypt, p. 212).
One grain of saffron rubbed to powder with sugar and a little water imparts a distinctly yellow tint to ten gallons of water.

On the light, poor sands of Saxony Herr Schultz, of Lupitz, made use of serradella, yellow lupins and vetches as green manures for enriching the land in humus and nitrogen, and found the addition of potash salts and phosphates very profitable for the subsequent growth of potatoes and wheat.
The coloration is generally sombre, but to this there are exceptions; the fruit-bats are brownish yellow or russet on the under surface; two South American species are white; Blainville's chin-leafed bat is bright orange; and the Indian painted bat (Cerivoula pieta) with its deep orange dress, spotted with black on the wing-membranes, has reminded observers of a large butterfly.
Sandy soils produce tobaccos with a thin leaf, curing to a yellow or bright red colour.
The leaves now ripen, indicated by a change from a dark to lighter green, and by the appearance of yellow spots.
The process, which requires great judgment and care, results in the bright yellow leaf so largely used for pipe tobacco, cigarettes and chewing tobacco.
Hungary produces tobacco of a rich, dark brown colour, useful for cigars, and also a small, bright yellow leaf, of value as a cigarette and pipe tobacco.
Stahl, as late as 1702, quoted the formation of brass as a case of the union of a metal with an earth into a metallic compound; but he subsequently adopted the view propounded by Kunckel in 1677, that "cadmia" is a metallic calx, and that it dyes the copper yellow by giving its metal up to it.
It is an infusible solid, which is intensely yellow at a red heat, but on cooling becomes white.
This at least is true of the oxide produced from the metal by combustion; that produced from the carbonate, if once made yellow at a red heat, retains a yellow shade permanently.
The precipitate, when heated, passes into oxide, which is yellow in the heat and white after cooling; and, if it be moistened with cobalt nitrate solution and re-heated, it exhibits a green colour after cooling.

In some of these the legs as well as the bill are yellow or orange; and in a few both sexes are glossy black.
Although it had long been suspected that these insects were in some way connected with malaria and other diseases, while that the species now called Stegomyia calopus was the carrier of yellow fever had been asserted by Finlay as early as 1881, it was not until the closing years of the 19th century that the brilliant researches of Ross in India, and of Grassi and others in Italy, directed the attention of the whole civilized world to mosquitoes as the exclusive agents in the dissemination of malarial fever.
Stegomyia calopus, on the other hand, a very widely distributed species and the almost certain carrier of yellow fever, belongs to the Culicinae.
There is reason to believe that malaria, yellow fever and filariasis are not the only diseases disseminated by mosquitoes.
TiN 2 is a dark blue powder obtained when the oxide is ignited in an atmosphere of ammonia; while TiN is obtained as a bronze yellow mass as hard as the diamond by heating the oxide in an atmosphere of nitrogen in the electric furnace.

The plants have long narrow leaves springing from the bulb and a central scape bearing one or more generally large, white or yellow, drooping or inclined flowers, which are enveloped before opening in a membranous spathe.
The flowers are large, yellow, scented and a little drooping, with a corolla deeply cleft into six lobes and a bell-shaped corona which is crisped at the margin; they appear in March or April.
They admit of being forced into early bloom, like the hyacinth and tulip. They vary with a white, creamy or yellow perianth, and a yellow, lemon, primrose or white cup or coronet; and, being richly fragrant, they are general favourites amongst spring flowers.
Jonquilla, with yellow flowers, a native of south Europe and Algeria, of which there are single and double flowered varieties, is also grown in pots for early flowering, but does well outside in a warm border.

It is a golden yellow bronze, called seniokuthis being the Japanese pronunciation of Suen-t, the era of the Ming dynasty of China when this compound was invented.
Salmon-colored, red, yellow and white glazes are also found, and in late specimens gilding was added.
The latter ceramist excelled also in the production of purple, green and yellow glazes, which he combined with admirable skill and taste.
But in Bokus time, and indeed as long as the factories flourished, many other kinds of faience were produced, the principal having rich black or fiamb glazes, while a few were green or yellow monochromes.
In many cases we find large portions of the surface completely covered with green or yellow enamel overlying black diapers or scroll patterns.
Nevertheless he persevered, and in 1838 we find him producing not only green and yellow monochromes, but also greyish white and mirror-black glazes of high excellence.
So thoroughly had he now mastered the management of glazes that he could combine yellow, green, white and claret color in regular patches to imitate tortoise-shell.
Chocolate or dove-colored grounds with delicate diapers in gold and engobe; brown or black faience with white, yellow and pink designs incised or in relief; pottery curiously and deftly marbled by combinations of various colored clays these and many other kinds are to be found, all, however, presenting one common feature, namely, skilful finger-moulding and a slight roughening of the surface as though it had received the impression of coarse linen or crape before baking.
The chief of the former is faience, having light grey, close Izumc pate and yellow or straw-colored glaze, with or without erwle to which is applied decoration in gold and green enamel.
Long-tailed, terrestrial and arboreal forms. The tree-snakes are mostly green above with the under parts white or yellow.
Another variety has a red back, with pairs of black crossbars, the bands of each pair being separated by a narrow yellow space; sides brown, dotted with black; belly dark green, the outer portion of each ventral shield being yellow,.
A still more remarkable resemblance exists in the shape and striking, red, black and yellow coloration between Scolecophis aemulus of Chihuahua and the poisonous Elaps fulvius, the American coral-snake, but Cope has been careful to point out that these two creatures are not known to inhabit the same district.
The majority are distinguished by the beautiful arrangement of their bright and highly ornamental colours; many species of Elaps have the pattern of the so-called coral-snakes, their body being encircled by black, red and yellow rings - a pattern FIG.
The under surface is yellow to reddish, with dark specks.
In general the main elevations of the two ranges form pairs lying opposite one another; the forms of both ranges are monotonous, but the colouring is splendid, especially when viewed from a distance; when seen close at hand only a few valleys with perennial streams offer pictures of landscape beauty, their rich green contrasting pleasantly with the bare brown and yellow mountain sides.
The small flowers are densely crowded on thick fleshy spikes, which are associated with, and often more or less enveloped by, a large leaf (bract), the so-called spathe, which, as in cuckoo-pint, where it is green in colour, Richardia, where it is white, creamy or yellow, Anthurium, where it is a brilliant scarlet, is often the most striking feature of the plant.
Gold has a characteristic yellow colour, which is, however, notably affected by small quantities of other metals; thus the tint is sensibly lowered by small quantities of silver, and heightened by copper.
Kriiss; the brightest lines are 6277, 59 60, 5955 and 5836 in the orange and yellow, and 5230 and 4792 in the green and blue.

While the colours on the metopes and triglyphs had faded somewhat, the border above them, topped with a cornice projecting 6 in., retained a most brilliant maeander pattern of red, blue and yellow, while below these were two bands of godroons of blue and red.
In the last case it becomes coated with a greyish-black layer of an oxide (dioxide (?)), at a red heat the layer consists of the trioxide (B1203), and is yellow or green in the case of pure bismuth, and violet or blue if impure; at a bright red heat it burns with a bluish flame to the trioxide.
Thus obtained it is a yellow powder, soluble in the mineral acids to form soluble salts, which are readily precipitated as basic salts when the solution is diluted.
It melts to a reddish-brown liquid, which solidifies to a yellow crystalline mass on cooling.

The rather small tubular yellow or red flowers are borne on simple or branched leafless stems, and are generally densely clustered.
The flowers issue from between the mammillae, towards the upper part of the stem, often disposed in a zone just below the apex, and are either purple, rose-pink, white or yellow, and of moderate size.
The spines are variously coloured, white and yellow tints predominating, and from the symmetrical arrangement of the areolae or tufts of spines they are very pretty objects, and are hence frequently kept in drawing-room plant cases.
The flowers, produced near the apex of the plant, are generally large and showy, yellow and rose being the prevailing colours.
They are fleshy shrubs, with rounded, woody stems, and numerous succulent branches, composed in most of the species of separate joints or parts, which are much compressed, often elliptic or suborbicular, dotted over in spiral lines with small, fleshy, caducous leaves, in the axils of which are placed the areoles or tufts of barbed or hooked spines of two forms. The flowers are mostly yellow or reddish-yellow, and are succeeded by pear-shaped or egg-shaped fruits, having a broad scar at the top, furnished on their soft, fleshy rind with tufts of small spines.
Mangrove swamps surround the town and epidemics of cholera, yellow fever and other tropical diseases have been frequent; but the unhealthiness of the climate is mitigated to some extent by the high tides which cover the marshes, and the invigorating breezes which blow in from the sea.
