VII.— jP. p. N. Gilletde Laumont. 



Francois Pierre Nicolas Gillet db Laumont, was born at 

 Paris, 28th May, 1747^ and was the son of Pierre Gillet, a cele- 

 brated advocate. Gillet de Laumont at first applied himself to the 

 study of law, and was made an advocate on the 8th August, 1768 ; 

 but on the formation of a new Parliament he left the profession of 

 the law, and underwent the mathematical examinations necessary 

 for admission into the military school. In 1772, he entered into 

 the royal grenadiers and distinguished himself so highly, that in less 

 than five months he rose from the rank of ensign to that of captain- 

 commandant. His passion for science was however so great, that in 

 1784, he abandoned the military career, and applied himself to the 

 study of mineralogy under Sage, Bournon, Manon, Daubenton, 

 Rome Delille, De la Meltiene, Hauy and Saussure. Previous to 

 this he had discovered the crystalline sandstone, in the forest of 

 Fontainebleau, and the true nature of the lignites in the clay of 

 the Paris bason. The same year he was nominated inspector of 

 mines, and surveyed the mines of Brittany and the Pyrenees. It 

 was on this occasion that he discovered in the mines of Huelgoat, 

 the green phosphate of lead and the beautiful efflorescent zeolite, 

 termed laumonite by Haiiy. In 1787 he surveyed the strata in the 

 neighbourhood of Paris, and determined the nature of the wood coal 

 of Verberie, Soissons, &c. In 1789 he presented to government 

 a memoir on the min^s of France. In 1792 he added to his own 

 collection of minerals, the magnificent cabinet of Rome Delille. In 

 1794 he organized along with Lefeveres and D'Hellencourt, Le 

 Lievre, and Fourcroy, the new school of mines. In 1801 he pre- 

 sented to the Royal Society of Agriculture, statistical tables of the 

 minerals of the department of Seine, and the same year read to the 

 institute a paper on the conversion of muriate of silver into native 

 silver by the use of zinc or iron. He describes also the tin mines
