La Grange. From a Bust in the Library of the Institute of France. Under the Superintendance of the Society for the Diffusion of Useful Knowledge.
Engraved by Rob.t Hart.
[London, Published by Charles Knight, Pall Mall East.] [n.d. c.1800.]
Scrap biography stuck down over publication line.
Joseph-Louis Lagrange (1736-1813) was a mathematician and astronomer born in Turin. His main scientific contributions are as one of the creators of the calculus of variations, deriving the Euler-Lagrange equations for extrema of functionals. He also invented a method of solving differential equations, and his treatise "Theorie des fonctions analytiques" laid down some of the foundations of group theory, anticipating Galois. He transformed Newtonian mechanics into what is now known as Lagrangian mechanics, which exhibits the mechanical "principles" as simple results of the variational calculus.
Ex Norman Blackburn Collection.

Sir John Ross, C.B. K.S.A. K.C.S. Captain in the Royal Navy.
Painted by B.R. Faulkner. Engraved by Rob.t Hart. Printed by Gaywood & Longworth.
London, Published 1834, by Captain J, Ross, R.N.
Sir John Ross (1777-1856), the Scottish Rear Admiral and Arctic explorer. He became an Arctic explorer after distinguished naval service in the Napoleonic Wars. In 1818, he made his first voyages in search of the Northwest Passage to China. However, deciding the route was blocked by mountains, Ross's reputation suffered when it was later shown that the mountains were an optical illusion. Ross rebounded by attracting funding, from the gin distiller Felix Booth, to command the first steam ship into the Arctic on another voyage to locate the Northwest Passage (1829-33).
