JOHANN VON LAMONT (1805-1879), Scottish-German astronomer and magnetician, was born at Braemar, Aberdeenshire, on the 13th of December 1805. He was sent at the age of twelve to be educated at the Scottish monastery in Regensburg, and apparently never afterwards returned to his native country. His strong bent for scientific studies was recognized by the head of the monastery, P. Deasson, on whose recommendation he was admitted in 1827 to the then new observatory of Bogenhausen (near Munich), where he worked under J. Soldner. After the death of his chief in 1835 he was, on H. C. Schumacher's recommendation, appointed to succeed him as director of the observatory. In 1852 he became professor of astronomy at the university of Munich, and held both these posts till his death, which took place on the 6th of August 1879. Lamont was a member of the academies of Brussels, Upsala and Prague, of the Royal Society of Edinburgh, of the Cambridge Philosophical Society and of many other learned corporations. Among his contributions to astronomy may be noted his eleven zonecatalogues of 34,674 stars, his measurements, in 1836-1837, of nebulae and clusters, and his determination of the mass of Uranus from observations of its satellites ( Mena. Astron. Soc. xi. 51, 1838). A magnetic observatory was equipped at Bogen Atlas range the food of this bird is said to consist chiefly of the Testudo mauritanica, which "it carries to some height in the air, and lets fall on a stone to break the shell" ( Ibis, 18 59, p. 1 77). It was the iipin and ohvn of Greek classical writers.

hausen in 1840 through his initiative; he executed comprehensive magnetic surveys 1849-1858; announced the magnetic decennial period irk 1850, and his discovery of earth-currents in 1862. His Handbuch des Erdmagnetismus (Berlin, 1849) is a standard work on the subject.

Lamoriciere, Christophe Leon Louis Juchault De (1806-1865), French general, was born at Nantes on the 1 1th of September 1806, and entered the Engineers in 1828. He served in the Algerian campaigns from 1830 onwards, and by 1840 he had risen to the grade of marechal-de-camp (majorgeneral). Three years later he was made a general of division. He was one of the most distinguished and efficient of Bugeaud's generals, rendered special service at Isly (August 14, 1844), acted temporarily as governor-general of Algeria, and finally effected the capture of Abd el-Kader in 1847. Lamoriciere took some part in the political events of 1848, both as a member of the Chamber of Deputies and as a military commander. Under the regime of General Cavaignac he was for a time minister of war. From 1848 to 1851 Lamoriciere was one of the most conspicuous opponents of the policy of Louis Napoleon, and at the coup d'etat of the 2nd of December 1851 he was arrested and exiled. He refused to give in his allegiance to the emperor Napoleon III., and in 1860 accepted the command of the papal army, which he led in the Italian campaign of 1860. On the 18th of September of that year he was severely defeated by the Italian army at Castelfidardo. His last years were spent in complete retirement in France (he had been allowed to return in 1857), and he died at Prouzel (Somme) on the 11th of September 1865.
