Prejudiced, no doubt, in favor of his own metaphysical views, Leibnitz himself misapprehended the principles of the Newtonian philosophy, and endeavored to demonstrate the truths in the _Principia_ by the application of different principles. Huygens, who above all other men was qualified to appreciate the new philosophy, rejected the doctrine of gravitation as existing between the individual particles of matter and received it only as an attribute of the planetary masses. John Bernouilli, one of the first mathematicians of his age, opposed the philosophy of Newton. Mairan, in the early part of his life, was a strenuous defender of the system of vortices. Cassini and Maraldi were quite ignorant of the _Principia_, and occupied themselves with the most absurd methods of calculating the orbits of comets long after the Newtonian method had been established on the most impregnable foundation; and even Fontenelle, a man of liberal views and extensive information, continued, throughout the whole of his life, to maintain the doctrines of Descartes. The chevalier Louville of Paris had adopted the Newtonian philosophy before 1720; Gravesande had introduced it into the Dutch universities at a somewhat earlier period; and Maupertuis, in consequence of a visit which he paid to England in 1728, became a zealous defender of it; but notwithstanding these and some other examples that might be quoted, we must admit the truth of the remark of Voltaire, that though Newton survived the publication of the _Principia_ more than forty years, yet at the time of his death he had not above twenty followers out of England. %MORGAN, THE BUCCANEER, SACKS PANAMA% A.D. 1671 JOHANN W. VON ARCHENHOLZ In the seventeenth century appeared "a class of rovers wholly distinct from any of their predecessors in the annals of the world, differing as widely in their plans, organizations, and exploits as in the principles that governed their actions." These adventurers were a piratical gang called buccaneers, or sometimes, as in the following narrative, freebooters, who became noted for their exploits in the West Indies and on South American coasts. The nucleus of this association of pirates is traced to bands of smugglers--English, French, and Dutch--who carried on a secret trade with the island of Santo Domingo. Later they settled there and on other islands, and after a while began to prey upon Spanish commerce. In 1630 they made their chief head-quarters on the island of Tortuga; in 1655 they aided in the English conquest of Jamaica, and ten years later settled the Bahamas. All these islands became centres of their activities.
