 finches, the proportionate length of the thigh-bone or femur to the tibia and foot (metatarsus and toes) is constant, being 2 to 5; in animals, on the other hand, such as hares, horses and frogs, which use all four feet, the corresponding lengths are 4 to 7. The resemblance between the jerboa’s and the bird’s skeleton is owing to adaptation to a similar mode of existence. In the young jerboa the proportion of the femur to the rest of the leg is the same as in ordinary running animals. Further, at an early stage of development the fibula is a complete and separate bone, while the three metatarsals, which subsequently fuse together to form the cannon-bone, are likewise separate. In addition to their long hind and short fore limbs, jerboas are mostly characterized by their silky coats—of a fawn colour to harmonize with their desert surroundings—their large eyes, and long tails and ears. As is always the case with large-eared animals, the tympanic bullae of the skull are of unusually large size; the size varying in the different genera according to that of the ears. (For the characteristics of the family and of its more important generic representatives, see .)

In the Egyptian jerboa the length of the body is 8 in., and that of the tail, which is long, cylindrical and covered with short hair terminated by a tuft, 10 in. The five-toed front limbs are extremely short, while the hind pair are six times as long. When about to spring, this jerboa raises its body by means of the hinder extremities, and supports itself at the same time upon its tail, while the fore-feet are so closely pressed to the breast as to be scarcely visible, which doubtless suggested the name Dipus, or two-footed. It then leaps into the air and alights upon its four feet, but instantaneously erecting itself, it makes another spring, and so on in such rapid succession as to appear as if rather flying than running. It is a gregarious animal, living in considerable colonies in burrows, which it excavates with its nails and teeth in the sandy soil of Egypt and Arabia. In these it remains during great part of the day, emerging at night in search of the herbs on which it feeds. It is exceedingly shy, and this, together with its extraordinary agility, renders it difficult to capture. The Arabs, however, succeed by closing up all the exits from the burrows with a single exception, by which the rodents are forced to escape, and over which a net is placed for their capture. When confined, they will gnaw through the hardest wood in order to make their escape. The Persian jerboa (Alactaga indica) is also a nocturnal burrowing animal, feeding chiefly on grain, which it stores up in underground repositories, closing these when full, and only drawing upon them when the supply of food above ground is exhausted (see also ).

JERDAN, WILLIAM (1782–1869), Scottish journalist, was born on the 16th of April 1782, at Kelso, Scotland. During the years between 1799 and 1806 he spent short periods in a country lawyer’s office, a London West India merchant’s counting-house, an Edinburgh solicitor’s chambers, and held the position of surgeon’s mate on board H.M. guardship “Gladiator” in Portsmouth Harbour, under his uncle, who was surgeon. He went to London in 1806, and became a newspaper reporter. He was in the lobby of the House of Commons on the 11th of May 1812 when Spencer Perceval was shot, and was the first to seize the assassin. By 1812 he had become editor of The Sun, a semi-official Tory paper; he occasionally inserted literary articles, then quite an unusual proceeding; but a quarrel with the chief proprietor brought that engagement to a close in 1817. He passed next to the editor’s chair of the Literary Gazette, which he conducted with success for thirty-four years. Jerdan’s position as editor brought him into contact with many distinguished writers. An account of his friends, among whom Canning was a special intimate, is to be found in his Men I have Known (1866). When Jerdan retired in 1850 from the editorship of the Literary Gazette his pecuniary affairs were far from satisfactory. A testimonial of over £900 was subscribed by his friends; and in 1853 a government pension of 100 guineas was conferred on him by Lord Aberdeen. He published his Autobiography in 1852–1853, and died on the 11th of July 1869.

JEREMIAH, in the Bible, the last pre-exilic prophet (fl. 626–586 ?), son of Hilkiah.

Early Days of Jeremiah.—There must anciently have existed one or more prose works on Jeremiah and his times, written partly to do honour to the prophet, partly to propagate those views respecting Israel’s past with which the name of Jeremiah was associated. Some fragments of this work (or these works) have come down to us; they greatly add to the popularity of the Book of Jeremiah. Strict historical truth we must not ask of them, but they do give us what was believed concerning Jeremiah in the following age, and we must believe that the personality so honoured was an extraordinary one. We have also a number of genuine prophecies which admit us into Jeremiah’s inner nature. These are our best authorities, but they are deficient in concrete facts. By birth Jeremiah was a countryman; he came of a priestly family whose estate lay at Anathoth “in the land of Benjamin” (xxxii. 3; cf. i. 1). He came forward as a prophet in the thirteenth year of Josiah (626 ), still young but irresistibly impelled. Unfortunately the account of the call and of the object of the divine caller come to us from a later hand (ch. i.), but we can well believe that the concrete fact which the prophetic call illuminated was an impending blow to the state (i. 13–16; cf. ch. iv.). What the blow exactly was is disputed, but it is certain that Jeremiah saw the gathering storm and anticipated its result, while the statesmen were still wrapped in a false security. Five years later came the reform movement produced by the “finding” of the “book of the law” in the Temple in 621 (2 Kings xxii. 8), and some critics have gathered from Jer. xi. 1–8 that Jeremiah joined the ranks of those who publicly supported this book in Jerusalem and elsewhere. To others this view appears in itself improbable. How can a man like Jeremiah have advocated any such panacea? He was indeed not at first a complete pessimist, but to be a preacher of Deuteronomy required a sanguine temper which a prophet of the school of Isaiah could not possess. Besides, there is a famous passage (viii. 8, see R.V.) in which Jeremiah delivers a vehement attack upon the “scribes” (or, as we might render, “bookmen”) and their “false pen.” If, as Wellhausen and Duhm suppose, this refers to Deuteronomy (i.e. the original Deuteronomy), the incorrectness of the theory referred to is proved. And even if we think that the phraseology of viii. 8 applies rather to a body of writings than to a single book, yet there is no good ground (xi. 1–8 and xxxiv. 12 being of doubtful origin) for supposing that Jeremiah would have excepted Deuteronomy from his condemnation.

Stages of his Development.—At first our prophet was not altogether a pessimist. He aspired to convince the better minds that the only hope for Israelites, as well as for Israel, lay in “returning” to the true Yahweh, a deity who was no mere national god, and was not to be cajoled by the punctual offering of costly sacrifices. When Jeremiah wrote iv. 1–4 he evidently considered that the judgment could even then be averted. Afterwards he became less hopeful, and it was perhaps a closer acquaintance with the manners of the capital that served to disillusionize him. He began his work at Anathoth, but v. 1–5 (as Duhm points out) seems to come from one who has just now for the first time “run to and fro in the streets of Jerusalem,” observing and observed. And what is the result of his expedition? That he cannot find a single just and honest man; that high and low, rich and poor, are all ignorant of the true method of worshipping God (“the way of Yahweh,” v. 4). It would seem as if Anathoth were less corrupt than the capital, the moral state of which so shocked Jeremiah. And yet he does not really go beyond the great city-prophet Isaiah who calls the men of Jerusalem “a people of Gomorrah” (i. 10). With all reverence, an historical student has to deduct something from both these statements. It is true that commercial prosperity had put a severe strain on the old morality, and that contact with other
