LEFT BOSA 114 BOSACEA shortness and coarseness of their baleen or whalebone, and the small quantity of oil they produce. The N. rorqual (Balae- noptera boops) attains a great size, being found from 80 to over 100 feet in length, and is thus the largest living animal known. The rorqual feeds on cod, herring, pilchards, and other fish, in pursuing which it is not seldom stranded on the shore. BOSA, CABL AUGUST NICHOLAS, originally Rose, a German opera manager and violinist; born in Hamburg, Ger- many, March 22, 1842. He was educated at the Leipsic Conservatory for a violinist, and appeared at the Crystal Palace in London, March 10, 1866. He soon came to the United States, where during a con- cert tour he met and married (in New York, in February, 1867) Mme. Parepa; formed an opera company, including Mme. Parepa-Rosa, Wachtel, Santley, Ronconi, and Formes, traveling as far as Cali- fornia.

BOSA, MONTE, a mountain or group of the Pennine Alps, on the frontiers of the Swiss canton of Valais and Piedmont, and forming part of the watershed be- tween the Rhone and the Po. Next to Mont Blanc it is the highest mountain in the Alps, but as a group it is much more massive than the Mont Blanc group. It has eight summits above 14,000 feet, the highest being Dufourspitze (15,217), ascended for the first time in 1855. Of the huge glaciers that occupy the slopes of this mountain the chief are the Gorner Glacier on the W., the Schwarzberg and Findelen Glaciers on the N., the Sesia and Macugnaga Glaciers on the E., and the Lys Glacier on the S. BOSA, SALVATOB, an Italian paint- er, etcher and poet; born near Naples, Italy, June 20, 1615. He received instruc- tion in art from his brother-in-law, Fran- cesco Fracanzaro, a pupil of Ribera, but his taste and skill were more influenced by his studies of nature on the Neapoli- tan coast. Rosa's father, dying in 1632, left his family in difficulties, and Salva- tor was compelled to sell his landscapes for small sums. One of his pictures fell into the hands of the painter Lanfranco, who at once recognized the genius of the youth and encouraged him to go to RomV In 1638 Rosa settled in Rome, where he soon established his reputation and rose to fame and wealth. The bitterness of his satire, expressed both in his satirical poems and in an allegorical painting of the "Wheel of Fortune" rendered his stay in Rome inadvisable. He therefore ac- cepted an invitation to Florence (1642), where he remained nearly nine years under the protection of the Medici. He finally returned to Rome. Salvator Rosa SALVATOR ROSA delighted in romantic landscape, delineat- ing scenes of gloomy grandeur and bold magnificence. He also painted battle scenes, and latterly historical pictures. His poems were all satires, vigorous enough and pungent; among them are "Babylon" (i.e., Rome), "Music," "Poet- ry," "Painting," "War," and "Envy." Rosa etched from his own works with great skill. He died in Rome, Italy, March 15, 1673.
