Juan de Sangara, and after an obstinate action captured five vessels and destroyed tvvo. After relieving Gibraltar and Minorca, he sailed again for this country, and met the French fleet, under Count de Guichen, near Martinique, 15 and IT April. Although no general battle was fought, he broke through the enemy's line and was re- warded by parliament with a vote of thanks and a pension of 2,000. He was elected to parliament for Westminster, created a K. B.. and in December, 1780, made an unsuccessful attack on St. Vincent, but in 1781 captured the Dutch colonies of St. Bustatius, Demerara, Essequibo, and Berbice. Re- turning to England in the autumn of 1781, he was appointed vii-i-admiral "I' Kii^l.'ind. ami a^M^ned to command in the West Indies. In April. 1782, he met, in the channel of Dominica, with Count de Grasse, who was escorting a convoy of 150 sail that carried an invading army to Jamaica, On 9 April a partial engagement was fought, and on 12 April, Rodney, having the advantage of the wind, attacked the French. The battle lasted nearly twelve hours, and was one of the most obstinate that was ever fought in those waters. As Vau- dreuil's division was unable, on account of the wind, to co-operate in the action, and Ue Grasse's flag-ship was sinking, the latter was compelled to lower his flag, the French losing seven ships and two frigates, and the English three vessels. Yau- dreuil abandoned the expedition to Jamaica, owing to subsequent orders, and a truce was signed, which led to the peace of 1783. The Whigs, who had meanwhile come into office, had despatched, before the victory was known, an officer to supersede Rodney, who arrived in England, 21 Sept., 1782. He was greeted with enthusiasm, elevated to the peerage as Baron Rodney, and received an addi- tional pension of 2,000, made revertible to his heirs. Owing to infirmities, he retired from a> live service. Jamaica, which he saved, voted 1,000 for the erection of a monument over his grave, and his portrait, by Sir Joshua Reynolds, is at Green- wich. Rodney's son-in-law, Gen. Godfrey Basil Mundy, published " Life and Correspondence of Lord Rodney " (2 vols., London, 1830).
RODRIGUEZ, Cayetano José (ro-dre-geth '),

entered the Franciscan order in 1777, and was or-

was director of the convents of Santa Catalina and
Santa Clara, and he also taught philosophy and
theology in the convent of Buenos Ayres and the.
University of Cordova. From the beginning of
his career as a teacher he foresaw the future inde-
pendence of his country, and when the Spanish
yoke was thrown off in 1810 he was one of the
most ardent followers of the patriotic cause. As
a representative of his native province he was a
member of the congress of Tucuman in 1816, and
as secretary of that body signed the act of inde-
pendence oil 25 July of that year. When, in 1822.
the ecclesiastic reform was initiated, Rodriguez
defended the rights of the church in the paper
" Oficial del Dia " with great force, and he is
considered one of the most "powerful writers of
that period. He was also a poet of great merit,
and many of his compositions appeared in maga-
zines, but no collection has been issued.

development of mathematics in Mexico.

the defeat of Cancha Rayada. when he proclaimed
himself chief of Santiago. The reorganized forces
obtained the victory of Maypu. in which Rodriguez took part as chief of the Husares de la Muerte. The- other chiefs, especially O'Higgins, began to be jealous of the popularity of Rodriguez.

mission to the United States. On his refusal his
death was decreed by the Lautaro secret society,
and soon afterward he was imprisoned and sent to
Quillota. to be tried by a court-martial. He was
delivered to an officer, Navarro, who on the road
ordered him to be shot without any trial. On the
place of his execution a granite column has been
erected, which was dedicated on 26 May, 1863.
RODRIGUEZ, Manuel del Socorro, Cuban
scientist, b. in Bayamo, Cuba, in 1758; d. in Bogo-
ta, Colombia, in 1818. Being of poor parentage,
he was obliged to work for a living from early life,
and received only a scanty education ; but he sup-
plied this deficiency by his energy and love for
study, and without -any teacher obtained a pro-
found knowledge of science, history, and literature.
He followed Jose de Ezpeleta in 1789 to New
Granada, and, being appointed director of the pub-
lic library of Bogota, began at once to aid the in-
tellectual development of the country, associating
his name with many literary and scientific enter-
prises for that purpose. At his suggestion the
viceroy founded the " Papel periodico de Santa Fe
de Bogota," the first newspaper in the colony, the
editorship of which was assigned to Rodriguez in
January, 1791. He suggested also the idea of
creating an astronomical and meteorological ob-
servatory, and was appointed one of its directors.
He founded several scientific and literary newspa-
pers and reviews. When the country revolted
against the Spanish rule in 1810, Rodriguez sided
with the patriots and shared their fortunes. Al-
though he wrote much, especially on scientific sub-
jects, many of his works are lost. The principal
manuscript that is preserved is " Historia de la
Fundaeion de la Ensenanza." Humboldt praises
him in several parts of his numerous writings.
