VITELLUS 239 VITORIA flattery. To these he owed his rapid rise and his favor with Tiberius, Caius Caligula, Claudius and Nero. On the death of Galba he was proclaimed em- peror by the soldiers at Koln, Jan. 2, A. D. 69, and having crushed his rival Otho he secured undisputed possession of Italy. Though undoubtedly a man of low character, he did not proceed to ex- treme measures against the adherents of his rival. His chief passion was sensual gluttony, and he spent enormous sums of money in eating and drinking. Vespa- sianus revolted, and was proclaimed em- peror July 1 at Alexandria, and Anto- nius Primus declared for the new em- peror and hastened into Italy at the head of a powerful force. He defeated the generals of Vitellius twice and en- tered Rome, Dec. 21 or 22, A. D. 69. The fallen emperor was seized, dragged with every mark of ignominy through the streets and murdered. VITELLUS, or YOLK, the name given to a part of the eggs or ova of animals. It varies in form and size in different eggs, some being "large-yolked," and others "small-yolked." The hen lays a large-yolked egg, the embryo being de- veloped from a mere speck on the sur- face, named the cicatricula or tread. The name vitellin was formerly given to the essential substance of which the vitellus was believed to consist, but this sub- stance has been shown to be merely a form of albumen and casein, and not a special product of organic chemistry. The vitellus consists of highly-concen- trated protoplasmic or albuminous mat- ter, along with mineral substances, and it contains the nutritive matter from which the early tissues of the embryo are formed. In many respects the egg yolk resembles milk in its nature. VITERBO, a town of Italy, province of Rome; 42 1/2 miles N. W. of the city of Rome.
