The colourproducing reagent is added and the tints compared.
This beautiful material presents a great diversity of tints, but a rich hyacinth red is common.
Coccinea, often confounded with the red oak, but with larger leaves, with long lobes ending in several acute points; they change to a brilliant scarlet with the first October frosts, giving one of the most striking of the various glowing tints that render the American forests so beautiful in autumn.
The bark, very dark externally, is an excellent tanning substance; the inner layers form the quercitron of commerce, used by dyers for communicating to fabrics various tints of yellow, and, with iron salts, yielding a series of brown and drab hues; the colouring property depends on a crystalline principle called quercitrin, of which it should contain about 8%.
Ihe great works of the Vatican are especially famous (more than 17,000 distinct tints are employed in their productions), and there are many other establishments in Rome.
The iris is in most young birds at first brown or dull-coloured, but with maturity attains often very bright tints which add considerably to the charm of the bird; sexual dimorphism is in this respect of common occurrence.
The deeper tints are, however, peculiar to the nuptial plumage, or are only to be faintly traced at other times, so that in winter the adults - and the young always - have a much plainer appearance, ashy-grey and white being almost the only hues observable.
In the following year he discovered rhodium; and at about the same time Smithson Tennant added two more to the list - iridium and osmium; the former was so named from the changing tints of its oxides (ipcs, rainbow), and the latter from the odour of its oxide (ovµA, smell).
The general procedure is to make a series of standard solutions containing definite quantities of the substance which it is desired to estimate; such a series will exhibit tints which deepen as the quantity of the substance is increased.
The first of these methods yields a hypsographical, or - if the sea-bottom be included, in which case all contours are referred to a common datum line - a bathy hypsographical map. Carl Ritter, in 1806, employed graduated tints, increasing in lightness on proceeding from the lowlands to the highlands; while General F.
Von Hauslab, director of the Austrian Surveys, in 1842, advised that the darkest tints should be allotted to the highlands, so that they might not obscure details in the densely peopled plains.
Thus Horsell, who was the first to introduce tints the ground, however, was made until towards the close of the 18th century, when horizontal contours and hachures regulated according to the angle of inclination of all slopes, were adopted.
Penck on a scale of 1: i,000,000, which has been undertaken by the leading governments of the world, the ground is shown by contours at intervals of ioo metres (to be increased to 200 and Soo metres in mountainous districts); the strata are in graded tints, viz.
Blue for the sea, green for lowlands up to 300 metres, yellow between 300 and Soo metres, brown up to 2000 metres, and reddish tints beyond that height.
Carla, compiled a contoured map of France (1791), and it only needed the introduction of graduated tints between these contours to secure a graphic picture of the features of the ground.
In the Atlantic Monthly, in 1862, appeared " Walking," " Autumn Tints " and " Wild_Apples "; in 1863, " Night and Moonlight."
The manakins are nearly all birds of gay appearance, generally exhibiting rich tints of blue, crimson, scarlet, orange or yellow in combination with chestnut, deep black, black and white, or olive green; and among their most obvious characteristics are their short bill and feeble feet, of which the outer toe is united to the middle toe for a good part of its length.

The qualities of the new Chinese schools were essentially those of the older dynasties: breadth, simplicity, a daringly calligraphic play of brush that strongly recalled the accomplishments of the famous scribes, anti a coloring that varied between sparing washes of flat local tints and a strength and brilliancy of decorative effort that rivalled even that of the Buddhist pictures.
From this period date most of the specimens best known outside Japan cleverly modelled figures of mythological beings and animals covered with lustrous variegated glazes, the general colors being grey or buff, with tints of green, chocolate, brown and sometimes blue.
If in the best specimens exquisite modelling, wonderful accuracy of finish and pates of interesting tints are found, such pieces are, none the less, stamped prominently with the character of utensils rather than with that of works of art.
The Imari ware, even though its thick biscuit and generally ungraceful shapes be omitted from the account, shows no enamels that can rival the exquisitely soft, broken tints of the famille rose; and the Kakiemon porcelain, for all its rich though chaste contrasts, lacks the delicate transmitted tints of the shell-like kwan-yao.
In the eyes of a Chinese connoisseur, no blue-and-white porcelain worthy of consideration exists, or ever has existed, except the kai-pien-yao, with its imponderable pdle, its wax-like surface, and its rich, glowing blue, entirely free from superficiality or garishness and broken into a thousand tints by the microscopic crackle of the glaze.
The difficulty of obtaining clear, rich tints was nearly prohibitive, and though success, when achieved, seemed to justify the effort, this class of ware never received much attention in Japan.
One species which is extremely common (Pelamis bicolor), and which is easily recognized by the black colour of its upper and the yellowish tints of its lower parts (both colours being sharply defined), has extended its range W.
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 colour of sea-water as it is seen on board ship is most readily determined by comparison with the tints of Forel's xanthometer or colour scale, which consists of a series of glass tubes fixed like the rungs of a ladder in a frame and filled with a mixture of blue and yellow liquids in varying proportions.
The colours range from deep black to pure white, passing through chestnut or bay, and many tints of brown or ashy-grey, while often the feathers are more or less closely barred with some darker shade, and the black is very frequently glossed with violet, blue or green - or, in addition, spangled with white grey or gold-colour.
Nearly a foot long, affording a striking contrast to the dark metallic tints of the rest of its plumage.
Sapphire is widely distributed through the gold-bearing drifts of Victoria, New South Wales and Queensland, but the blue colour of the Australian stones is usually dark, and it is notable that green tints are not infrequent.
Northern and eastern Europe is inhabited by a larger form (P. major), which differs in nothing but size and more vivid tints from that which is common in the British Isles and western Europe.
Teydea) - all of which, while possessing the general appearance of the European bird, are clothed in soberer tints.'
The variegated plumage of the Snipe is subject to no inconsiderable variation, especially in the extent of dark markings on the belly, flanks, and axillaries, while examples are occasionally seen in which no trace of white, and hardly any of buff or grey, is visible, the place of these tints being taken by several shades of chocolate-brown.
The tints and hues of some of the pools are of matchless beauty.
In other species of the genus, 14 to 17 in number, the bill is mostly particoloured - green, yellow, red, chestnut, blue and black variously combining so as often to form a ready diagnosis; but some of these tints are very fleeting and often leave little or no trace after death.
The leaves of both assume rich purple-red tints in autumn.
They seem also never to walk or run when on the ground, but always to hop. The bodyfeathers are commonly loose and soft; and, gaily coloured as are most of the species, in few of them has the plumage the metallic glossiness it generally presents in the pies, while the proverbial beauty of the "jay's wing" is due to the vivid tints of blue - turquoise and cobalt, heightened by bars of jet-black, an indication of the same style of ornament being observable in the greater FIG.
In this bird and its many allied forms, coloration, though almost confined to various tints of blue, seems to reach its climax, but want of space forbids more particular notice of them, or of the members of the other genera Cyanocitta, Cyanocorax, Xanthura, Psilorhinus, and more, which inhabit various parts of the Western continent.
Absolutely colourless stones are not so common as cloudy and faintly coloured specimens; the usual tints are grey, brown, yellow or white; and as rarities, red, green, blue and black stones have been found.
In doing so they frequently change colour, and hence arise the beautiful and varied tints of the autumnal foliage.
The brown tints often seen in glazed objects are almost always the result of the decomposition of green glazes containing iron.
The brilliancy and fair light scale of his tints is constantly remarkable, combined with a free use of gilding; this conduces materially to that celestial character which so pre-eminently distinguishes his pictured visions of the divine persons, the hierarchy of heaven and the glory of the redeemed.
The black pine, P. austriaca, generally now regarded as a variety of P. Laricio, derives its name from the extreme depth of its foliage tints - the sharp, rigid, rather long leaves of a dark green hue giving a sombre aspect to the tree.

The famous Pictured Rocks in Alger county on the lake shore, east of Munising, form the west portion of this north range; they are of sandstone formation, extend for several miles along the coast, rise almost perpendicularly from the water's edge, and display an interesting diversity of shapes as well as a great variety of tints and hues, especially of gray, blue, green and yellow.
About as big as a crow, its plumage exhibits the blended tints of chocolate-colour and grey, barred and pencilled with dark-brown or black, and spotted in places with white, that prevail in the two families just named.
Any attempt to classify examples by their colours fails, for, while at some periods the particular tints employed in certain chanceries may have been selected with a view to marking the character of the documents so sealed, such practice was not consistently followed.
The African golden-moles (Chrysochloris), the desmans or water-moles (Myogale), and the West African Potamogale velox, are remarkable as being the only mammals whose hair reflects those iridescent tints so common in the feathers of tropical birds.
While the price of the finest tints of rose pink may range from go to £1 20 per oz., ordinary red-coloured small pieces sell for about £2 per oz., and the small fragments called collette, used for children's necklaces, cost about 5s.
