Rodent Ulcer.—This shows itself as a slowly progressing ulceration of the skin, and is especially common on the face near the eye or ear. The condition is one, of purely local malignancy, and dissemination does not occur. It is believed to be a carcinoma of the sebaceous glands of the skin.  (L. C.*) 


TUMULUS, a Latin word meaning a heap or mound, also in classical writings in the secondary sense of a grave. In Roman epitaphs we meet with the formula tumulum faciendum curavit, meaning the grave and its monument; and on the inscribed monumental stones placed over the early Christian graves of Gaul and Britain the phrase in hoc tumulo jacet expresses the same idea. But among archaeologists the word is usually restricted in its technical modern application to a sepulchral mound of greater or less magnitude. The mound may be of earth, or of stones with a covering of earth, or may be entirely composed of stones. In the latter case, if the tumulus of stones covers a megalithic cist or a sepulchral chamber with a passage leading into it from the outside, it is often called a dolmen. (See Stone Monuments, Barrow and Cairn.) The custom of constructing sepulchral tumuli was widely prevalent throughout the prehistoric ages and is referred to in the early literature of various races as a fitiing commemoration of the illustrious dead. Prehistoric tumuli are found abundantly in almost all parts of Europe and Asia from Britain to Japan. They occur with frequency also in northern Africa, and in many parts of North and South America the aboriginal populations have practised similar customs. Sepulchral tumuli, however vary so much in shape and size that the external appearance is no criterion of age or origin. In North America, especially in the Wisconsin region, there are numerous mounds made in shapes resembling the figures of animals, birds or even human forms. These have not been often found to be sepulchral, but they are associated with sepulchral mounds of the ordinary form, some of which are as much as 300 ft. in diameter and 90 ft. in height. Perhaps the largest tumulus on record is the tomb of Alyattes, king of Lydia, situated near Sardis, constructed in his own lifetime, before 560 B.C. It is a huge mound, 1180 ft. in diameter and 200 ft. high. In south-eastern Europe, and especially in southern Russia, the sepulchral tumuli are very numerous and often of great size, reaching occasionally to 400 ft. in circumference and over 100 ft. in height. These are mostly of the period of the Greek colonies of the Tauric Chersonese, dating from about the 5th century B.C. to about the 2nd century A.D., and their contents bear striking testimony to the wealth and culture of the people who reared them.

TUN, a town in the province of Khorasan, Persia, situated about 150 m. S. of Nishapur in 34° N., 58° 7' E., at an elevation of 1200 ft. The town, which has a population of 7000, is surrounded by a wall, 20 ft. in height, raised on a high rampart of mud. It has three gates, handsome bazaars, good caravanserais and numerous large gardens and fields producing opium, tobacco and cotton. Some silk is also grown.


TUNBRIDGE WELLS, a municipal borough and inland watering-place of England, chiefly in the Tonbridge parliamentary division of Kent, but extending into the eastern division of Sussex, 34½ m. S.E. by S. of London by the South Eastern & Chatham railway, served also by a branch of the London Brighton & South Coast line. Pop. (1891), 29,296; (1901), 33,375. It owes its popularity to its chalybeate springy and its beautiful situation in a hilly wooded district. The wells are situated by the Parade (or Pantiles), a walk associated with fashion since the time of their discovery. It was paved with pantiles in the reign of Queen Anne. Reading and assembly rooms adjoin the pump-room. The town is built in a picturesquely irregular manner, and a large part of it consists of districts called “ parks ” occupied by villas and mansions. On Rusthall Common about a mile from the town is the curiously shaped mass of sandstone known as the Toad Rock, and a mile and a half south-west is the striking group called the High Rocks. The Tunbridge Wells sanatorium is situated in grounds sixty acres in extent. Five miles south-east of Tunbridge Wells is Bayham Abbey, founded in 1200, where ruins of a church, a gateway, and dependent buildings adjoin the modern Tudor mansion. Three miles south, in Sussex, the village of Frant stands on a hill which is perhaps the finest of the many view-points in this district, commanding a wide prospect over some of. the richest woodland scenery in England. The vicinity of Tunbridge Wells is largely residential. To the north lies the urban district of Southborough (pop. 6977). There is a. large trade in Tunbridge ware, which includes work-tables, boxes, toys, &c., made of hard woods, such as beech, sycamore, holly, and cherry, and inlaid with mosaic. Tunbridge Wells was incorporated in 1889, and is governed by a mayor, 8 aldermen and 24 councillors. Area, 3991 acres.

The town owes its rise to the discovery of the medicinal springs by Dudley, Lord North, in 1606. Henrietta Maria, wife of Charles I., retired to drink the waters at Tunbridge Wells after the birth of her eldest son Charles. Soon after the Restoration it was visited by Charles II. and Catherine of Braganza. It was a favourite residence of the princess Anne previous to her accession to the throne, and from that time became one of the chief resorts of London fashionable society. In this respect it reached its height in the second half of the 18th century, and is specially associated with Colley Cibber, Samuel Johnson, Cumberland the dramatist, David Garrick, Samuel Richardson, Sir Joshua Reynolds, Beau Nash, Miss Chudleigh and Mrs Thrale. The Tunbridge Wells of that period is sketched with much graphic humour in Thackeray's Virginians.
