 its substance. He has been excessively praised by Schopenhauer, whose appreciation of the author induced him to translate the Oráculo manual, and he has been unduly depreciated by Ticknor and others. He is an acute thinker and observer, misled by his systematic misanthropy and by his fantastic literary theories.

  GRACKLE (Lat. Gracculus or Graculus), a word much used in ornithology, generally in a vague sense, though restricted to members of the families Sturnidae belonging to the Old World and Icteridae belonging to the New. Of the former those to which it has been most commonly applied are the species known as mynas, mainas, and minors of India and the adjacent countries, and especially the Gracula religiosa of Linnaeus, who, according to Jerdon and others, was probably led to confer this epithet upon it by confounding it with the Sturnus or Acridotheres tristis, which is regarded by the Hindus as sacred to Ram Deo, one of their deities, while the true Gracula religiosa does not seem to be anywhere held in veneration. This last is about 10 in. in length, clothed in a plumage of glossy black, with purple and green reflections, and a conspicuous patch of white on the quill-feathers of the wings. The bill is orange and the legs yellow, but the bird’s most characteristic feature is afforded by the curious wattles of bright yellow, which, beginning behind the eyes, run backwards in form of a lappet on each side, and then return in a narrow stripe to the top of the head. Beneath each eye also is a bare patch of the same colour. This species is common in southern India, and is represented farther to the north, in Ceylon, Burma, and some of the Malay Islands by cognate forms. They are all frugivorous, and, being easily tamed and learning to pronounce words very distinctly, are favourite cage-birds.

In America the name Grackle has been applied to several species of the genera Scolecophagus and Quiscalus, though these are more commonly called in the United States and Canada “blackbirds,” and some of them “boat-tails.” They all belong to the family Icteridae. The best known of these are the rusty grackle, S. ferrugineus, which is found in almost the whole of North America, and Q. purpureus, the purple grackle or crow-blackbird, of more limited range, for though abundant in most parts to the east of the Rocky Mountains, it seems not to appear on the Pacific side. There is also Brewer’s or the blue-headed grackle, S. cyanocephalus, which has a more western range, not occurring to the eastward of Kansas and Minnesota. A fourth species, Q. major, inhabits the Atlantic States as far north as North Carolina. All these birds are of exceedingly omnivorous habit, and though destroying large numbers of pernicious insects are in many places held in bad repute from the mischief they do to the corn-crops.

 GRADISCA, a town of Austria, in the province of Görz and Gradisca, 10 m. S.W. of Görz by rail. Pop. (1900) 3843, mostly Italians. It is situated on the right bank of the Isonzo and was formerly a strongly fortified place. Its principal industry is silk spinning. Gradisca originally formed part of the margraviate of Friuli, came under the patriarchate of Aquileia in 1028, and in 1420 to Venice. Between 1471 and 1481 Gradisca was fortified by the Venetians, but in 1511 they surrendered it to the emperor Maximilian I. In 1647 Gradisca and its territory, including Aquileia and forty-three smaller places, were erected into a separate countship in favour of Johann Anton von Eggenberg, duke of Krumau. On the extinction of his line in 1717, it reverted to Austria, and was completely incorporated with Görz in 1754. The name was revived by the constitution of 1861, which established the crownland of Görz and Gradisca.

 GRADO, a town of northern Spain, in the province of Oviedo; 11 m. W. by N. of the city of Oviedo, on the river Cubia, a left-hand tributary of the Nalon. Pop. (1900) 17,125. Grado is built in the midst of a mountainous, well-wooded and fertile region. It has some trade in timber, live stock, cider and agricultural produce. The nearest railway station is that of the Fabrica de Trubia, a royal cannon-foundry and small-arms factory, 5 m. S.E.

 GRADUAL (Med. Lat. gradualis, of or belonging to steps or degrees; gradus, step), advancing or taking place by degrees or step by step; hence used of a slow progress or a gentle declivity or slope, opposed to steep or precipitous. As a substantive, “gradual” (Med. Lat. graduale or gradale) is used of a service book or antiphonal of the Roman Catholic Church containing certain antiphons, called “graduals,” sung at the service of the Mass after the reading or singing of the Epistle. This antiphon received the name either because it was sung on the steps of the altar or while the deacon was mounting the steps of the ambo for the reading or singing of the Gospel. For the so-called Gradual Psalms, cxx.-cxxxiv., the “songs of degrees,” LXX. , see.

GRADUATE (Med. Lat. graduare, to admit to an academical degree, gradus), in Great Britain a verb now only used in the academical sense intransitively, i.e. “to take or proceed to a university degree,” and figuratively of acquiring knowledge of, or proficiency in, anything. The original transitive sense of “to confer or admit to a degree” is, however, still preserved in America, where the word is, moreover, not strictly confined to university degrees, but is used also of those successfully completing a course of study at any educational establishment. As a substantive, a “graduate” (Med. Lat. graduatus) is one who has taken a degree in a university. Those who have matriculated at a university, but not yet taken a degree, are known as “undergraduates.” The word “student,” used of undergraduates e.g. in Scottish universities, is never applied generally to those of the English and Irish universities. At Oxford the only “students” are the “senior students” (i.e. fellows) and “junior students” (i.e. undergraduates on the foundation, or “scholars”) of Christ Church. The verb “to graduate” is also used of dividing anything into degrees or parts in accordance with a given scale. For the scientific application see below. It may also mean “to arrange in gradations” or “to adjust or apportion according to a given scale.” Thus by “a graduated income-tax” is meant the system by which the percentage paid differs according to the amount of income on a pre-arranged scale.
