MALTZAN—MALVACEAE

gave the castle and its appurtenances to Eustace son of John, whose descendants took the name of Vescy. Eustace meditated the deliverance of Malton Castle to King David of Scotland in 1138, but his plans were altered owing to the battle of the Standard. The “ burgh ” of Malton is mentioned in 1187, and in 1295 the town returned two members to parliament. It was not represented again, however, until 1640, when an act was passed to restore its ancient privileges. In 1867 the number of members was reduced to one, and in 1885 the town was disfranchised. Until the 17th century the burgesses had all the privileges of a borough by prescriptive right, and were governed by two bailiffs and two under-bailiffs, but these liberties were taken from them in 1684 and have never been revived. From that time a bailiff and two Constables were appointed at the court leet of the lord of the manor until a local board was formed in 1854. In the 13th century Agnes de Vescy, then lady of the manor, held a market in Malton by prescription, and Camden writing about 1586 says that the lord of the manor then held two weekly markets, on Tuesday and Saturday, the last being the best cattle market in the county. The markets are now held on Saturdays and alternate Tuesdays, and still belong to the lord of the manor.


MALTZAN, HEINRICH VON, Baron zu Wartenburg und Penzlin (1826–1874), German traveller, was born on the 6th of September 1826 near Dresden. He studied law at Heidelberg, but on account of ill health spent much of his time from 1850 in travel. Succeeding to his father's property in 1852, he extended the range of his journeys to Morocco and other parts of Barbary, and before his return home in 1854 had also visited Egypt, Palestine and other countries of the Levant. In 1856–1857 he was again in Algeria; in 1858 he reached the city of Morocco; and in 1860 he succeeded in performing the pilgrimage to Mecca, which he afterwards described in Meine Wallfahrt nach Mecca (Leipzig, 1865), but had to flee for his life to Jidda without visiting Medina. He then visited Aden and Bombay, and after some two years of study in Europe again began to wander through the coasts and islands of the Mediterranean, repeatedly visiting Algeria. His first book of travel, Drei Jahre im Nordwesten von Afrika (Leipzig), appeared in 1863, and was followed by a variety of works and essays, popular and scientific. Maltzan's last book, Reise nach Südarabien (Brunswick, 1873), is chiefly valuable as a digest of much information about little-known parts of south Arabia collected from natives during a residence at Aden in 1870–1871. Among his other services to science must be noticed his collection of Punic inscriptions (Reise in Tunis und Tripolis, Leipzig, 1870), and the editing of Adolph von Wrede's remarkable journey in Hadramut (Reise in Hadramaut, &c., Brunswick, 1870). After long suffering from neuralgia, Maltzan died by his own hand at Pisa on the 23rd of February 1874.


MALUS, ÉTIENNE LOUIS (1775–1812), French physicist, was born at Paris on the 23rd of June 1775. He entered the military engineering school at Mezières; but, being regarded as a suspected person, he was dismissed without receiving a commission, and obliged to enter the army as a private soldier. Being employed upon the fortifications of Dunkirk, he attracted the notice of the director of the works, and was selected as a member of the École polytechnique then to be established under G. Monge. After three years at the École he was admitted into the corps of engineers, and served in the army of the Sambre and Meuse; he was present at the passage of the Rhine in 1797, and at the affairs of Ukratz and Altenkirch. In 1798 he joined the Egyptian expedition and remained in the East till 1801. On his return he held official posts successively at Antwerp, Strassburg and Paris, and devoted himself to optical research. A paper published in 1809 (“ Sur une propriété de la lumière réfléchie par les corps diaphanes ”) contained the discovery of the polarization of light by reflection, which is specially associated with his name, and in the following year he won a prize from the Institute with his memoir, “ Théorie de la double refraction de la lumière dans les substances crystallines." He died of phthisis in Paris on the 23rd of February 1812.


MALVACEAE, in botany, an order of Dicotyledons belonging to the series Columniferae, to which belong also the orders Tiliaceae (containing Tilia, the lime-tree), Bombaceae (containing Adaiisonia, the baobab), Sterculiaceae (containing Theobroma, cocoa, and Colo, cola-nut). It contains 39 genera with about goo species, and occurs in all regions except the coldest, the number of species increasing as we approach the tropics. It is represented in Britain by three genera: Malva, mallow; Althaea, marsh-mallow; and Lavatera, tree-mallow. The plants are herbs, as in the British mallows, or, in the warmer parts of the earth, shrubs or trees. The leaves are alternate and often palmately lobed or divided; the stipules generally fall early. The leaves and young shoots often bear stellate hairs and the tissues contain rnucilage-sacs. The regular, hermaphrodite, often showy Bowers are borne in the leaf-axils, solitary or in fasicles, or form more

or less complicated cymose

arrangements. An epicalyx (see

MALLOW, figs. 3, 4), formed by a

whorl of three or more bracteoles

is generally present just beneath

the calyx; sometimes, as in

Abutilon, it is absent. The

parts of the flowers are typically

in tives (fig. 1); the five sepals,

which have a valvate aestivation,

are succeeded by five often large

showy petals which are twisted

in the bud; they are free to the base, where they are attached to the staminal tube and fall with it when the flower Withers. The very numerous stamens are regarded as arising from the branching of a whorl of five opposite the petals; they are united into a tube at the base, and bear kidney-shaped one-celled anthers which open by a slit across the top (fig. 2). The large spherical pollen-grains are covered

with spines. The carpels

are one to numerous; when five

in number, as in Abulilon, they

are opposite the petals, or, as in I H ibiscus, opposite the sepals.

forming a whorl round the top

flower, the united styles rising

corresponding number of stigmatic

branches. In M alope the

numerous carpels are arranged one above the other in vertical rows. One or more anatropous ovules are attached to the inner angle of each carpel; they are generally ascending but sometimes pendulous or horizontal; the position may vary, as in Abutilon, in one and the same carpel.

The flowers are proterandrous; when the Bower opens the unripe stigmas are hidden in the staminal tube and the anthers occupy the centre of the flower; as the anthers dehisce the filaments bend backwards and finally the ripe stigmas spread in the centre. Pollination is effected by insects which visit the flower for the honey, which is secreted in pits one between the base of each petal and is protected from rain by hairs on the lower margin of the petals. In small pale-flowered forms, like Malva rotundifolia, which attract few insects, self-pollination has been observed, the style-arms twisting to bring the stigmatic surfaces into contact with the anthers.

Except in M alvaviscus which has a berry, the fruits are dry. In Malva (see MALLOW) and allied genera they form one-seeded schizo carps separating from the persistent central column and from each other. In Hibiscus and Gossypium (cotton-plant, q.v.), the fruit is a capsule splitting loculicidally. Distribution of the seeds is sometimes aided by' hooked outgrowths on the wall of the schizo carp, or by a hairy covering on the seed, an extreme case of which is the cotton-plant where the seed is buried
