third deals with language, and the fourth lays down the limits of the understanding.  Other works of his are Thoughts concerning Education (1693), On the Conduct of the Understanding (pub. posthumously), The Reasonableness of Christianity (1695), Treatise on Government, and Letters on Toleration.  If not a very profound or original philosopher L. was a calm, sensible, and reasonable writer, and his books were very influential on the English thought of his day, as well as on the French philosophy of the next century.  His style is plain and clear, but lacking in brightness and variety.

Lives by Lord King (1829), and Bourne (1876). Works ed. by Prof.  A.C.  Fraser (1894). See also T.H.  Green’s Introduction to Hume (1874).

LOCKER-LAMPSON, FREDERICK (1821-1895).—­Poet, s. of the sec. of Greenwich Hospital, held appointments in Somerset House and the Admiralty.  He wrote a number of clever vers de societe, which were coll. as London Lyrics (1857).  He also compiled Lyra Elegantiarum, an anthology of similar verse by former authors, and Patchwork, a book of extracts, and wrote an autobiography, My Confidences (1896).

LOCKHART, JOHN GIBSON (1794-1854).—­Novelist and biographer, s. of a minister of the Church of Scotland of good family, was b. at Cambusnethan, Lanarkshire, and ed. at Glasgow and Oxf.  He studied law at Edin., and was called to the Scottish Bar in 1816, but had little taste for the profession.  Having, however, already tried literature (he had translated Schlegel’s Lectures on the History of Literature), he devoted himself more and more to a literary life.  He joined John Wilson, and became one of the leading contributors to Blackwood’s Magazine.  After bringing out Peter’s Letters to his Kinsfolk (1819), sketches mainly of Edinburgh society, he produced four novels, Valerius (1821), Adam Blair (1822), Reginald Dalton (1824), and Matthew Wald (1824).  His Life of Burns appeared in 1828.  He was ed. of the Quarterly Review 1824-53.  In 1820 he had m. Sophia, dau. of Sir Walter Scott, which led to a close friendship with the latter, and to his writing his famous Life of Scott, undoubtedly one of the greatest biographies in the language.  His later years were overshadowed with deep depression caused by the death of his wife and children.  A singularly reserved and cold manner led to his being regarded with dislike by many, but his intimate friends were warmly attached to him.
