1. RUSSIANS. The Russians of Slavic origin form the bulk of the population of the European part of Russia. All the middle provinces of this vast empire are occupied almost exclusively by a people of purely Slavic extraction. The numerous Slavi who are scattered through Asiatic Russia, are of the same race. They belong to the Greek Church. To ascertain the exact numbers of the different races of one and the same nation, is exceedingly difficult. The statistical tables of the government afford little help; since it is the policy of the latter to annihilate as much as possible the difference of races. Schaffarik, in his Slavic Ethnography, gives the number of the Russians proper at 38,400,000. We follow him, as the most diligent and most consistent investigator of this matter; but we also feel bound to remark, that his statistical assertions have occasioned surprise, and met with contradiction. 2. RUSSNIAKS or RUTHENIANS, also called _Russinians_ and _Malo-Russians_. These are found in Malo-Russia, the South of Poland, Galicia, Ludomeria or Red Russia, the Bukovina, also in the north-eastern part of Hungary, and scattered over Walachia and Moldavia. The Kozaks, especially the Zaporogueans, belong chiefly to this race; while the Kozaks of the Don are more mixed with pure Russians. Their number is given at more than thirteen millions. They all belong to the Oriental Church; though a portion of them are Greek-Catholics, or adherents of the United Church. II. ILLYRICO-SERVIAN BRANCH. 1. The ILLYRICO-SERVIANS proper, frequently called _Rascians_ or _Raitzi_, comprising five subdivisions. a) The SERVIANS in Servia, lying between the rivers Timock, Drina, Save, the Danube, and the Balkan mountains; and, as a Turkish province, called Serf Vilayeti. Their number is at least a million. In earlier times, and especially at the end of the seventeenth century, many of them emigrated to Hungary; where even now between three and four hundred thousand of them are settled; exclusive of their near relatives, the Slavonians, in the kingdom of Slavonia so called. b) BOSNIANS, between Dalmatia, the Balkan mountains, and the rivers Drina, Verbas, and Save; from four to five hundred thousand in number. Most of them belong, like their brethren the Servians, to the Greek Church; about 100,000 are Roman Catholics. There are of late many Muhammedans among them, who still retain their language and most of their Slavic customs.
