* SIMEON. 181 SIMILARITY. for a probably reliable record by the Chronicler (1. Chron. iv. 24 et seq. ) of an expansion of the tribe in King Hezekiah's time, evt-n as far as the laud of Seir. It does not figure at the division of the kingdom, nor is there any reference to Simeon upon the return. (An old tradition reads Simeon for Shimei in Zechariah xii. 13.) With this disappearance of the tribe goes the tes- timony of its non-mention in 'Moses's blessing' (Ueut. xxxiii. ). The legends of patriarchal times therefore stand for the historic fact that Simeon, a border tribe, early lost its identity, partly through war. partly through amalgamation with Judah or with desert trilies, with whioli history may be compared the fate of Dan. Consult: Graf, Der Stamm Simeon (Meissen, 1866) ; Steuernagel, Einicanderung der israelitischen S 111 III me { Berlin, 1001 ) . SIMEON, or SYMEON ( ?-c.927 ) . A Bul- garian ruler, son of the Boris who introduced Christianity, which was establishpd firmly by Simeon. He was the first Prince of Bulgaria to take the style of Czar or Emperor of all the Greeks and Bulgarians, upon coming to the throne in 890. His greatest fame was as a war- rior. He thrice laid siege to Constantinople, and in 803 concluded a treat}' by which the city became tributary to him, as Servia also was during most of his reign. SIMEON, Cn.RLES (1759-1836). An eminent evangelical preacher of the English Church. He was born at Reading in Berkshire; educated at Eton and King's College, Cambridge, and was or- dained a priest in 1783. He was appointed vicar of Trinity Church, Cambridge, in the year of his ordination, and held this office to the close of his life. As a preacher Simeon was distin- guished for an impassioned evangelicalism in language, sentiment, and doctrine, that at first roused against him a bitter and protracted oppo- sition. His earnestness, however, met with its due reward. 'Friends and followers sprang up ; and in course of time Simeon became a centre of evangelical influence, that spread itself over the whole Church. His entire works, including a homiletical commentary on the Bible, have been publi.shed (21 vols., London, 1840) ; also selec- tions (2 vols., 18.54). Consult his biography by Carus (London, 1847) and by Moule (ib., 1892) ; also A. W. Srov/n, Kecollections of Simeon's Con- versation Parties (ib., 1862). SIMEON STYLITES. See Pillar S.int. SIMFEROPOL, sem'fe-ro'p61-y'. The capital of the Government of Taurida, .South Russia, sit- uated in the southwestern part of the Crimean peninsula, about 200 miles southeast of Odessa ( Map : Russia, D 6 ). It has a separate quarter for the Tatar inhabitants, and a number of mosques. There are some manufactures of flour and tobacco, and an export trade in fruits and wine. Population, in 1897. 48.821, including many Tatars. Simferopol occupies the site of the Tatar settlement of Ak-metchet. SIMIID.^. The family of simian or anthro- poid apes. See Ape. SIMILARITY ( from similar, from Lat. simi- Us, similar, like; connected with simul. together, Gk. o^o, hama. together, Skt. savia, like, equal, same, and ultim.ately with Eng. same). In geom- etry, the theory of similar systems and similar figures. Two systems of points A,, B„ C,, and Aj, Bj, C^, are said to be similar when CONCENTKIC CIRCLES. they can be so placed that all lines, AjA,, BiB,, CjC,, joining corresponding points form a ANY CIRCLKB. pencil whose vertex, O, divides each line into segments having a constant ratio r. ANY LINE-SEfiMENTS. In the figures OAj : OA, = OBi : OB, = = »-. T'o figures are said to be similar when their systems of points are similar. The sjTnbol FOUR SIMILAR TRIANGLES. CO, for similarity, is due to Leibnitz and is de- rived from the letter S. When two similar figures are so placed that lines through their corresponding points form a jiencil, they are said to be in perspective, and the vertex of the pencil is called their centre of similitude. The above figures are placed in per- spective, and in each case O is the centre of similitude. In similar figures, if the ratio, r, known as the ratio of similitude, is 1, the figures are evidently symmetric with respect to a centre.
