On the aberration of compound lenses and object-glasses. Read March 22, 1821.
London, W. Bulmer and W. Nicol, 1821. 4to. No wrappers as extracted from ""Philosophical Transactions"" 1821 - Part I. With titlepage to Part I. Pp. 222-267 a. 1 engraved plate. Verso of titlepage with 2 stamps.
First appearance of this importent paper in optical theory in which Herschel described how to free lenses from the aberration for two axis points, one of which is infinitely distant. It is known as Herschel's condition. ""Sir John Herschel gave the condition which must be satisfied in order that a symmetrical optical system, free from spherical aberration for two conjugate axial points, may also be free from spherical aberration for two neighbouring and conjugate points upon the axis of the system" but Herschel's condition applies only to first order aberration, i.e. to aberration depending upon the cube of the inclination of the ray to the axis. Abbe shewed, later, that this condition could be included in a wider result, viz. that the spherical aberration, supposed zero, is stationary for axial variations provided that the incident and emergent rays for two conjugate axial points, associated with modified magnification m, satisfy the relation.

On the action of crystallized bodies on homogenous light, and on the causes of the derivation from newton's scale in the tints which many of them develope on exposure to a polarized ray. Read december 23, 1819.
London, W. Bulmer and Co., 1820. 4to. No wrappers as extracted from ""Philosophical Transactions"" 1820 - Part I. Pp. 45-100 a. 1 engraved plate.
First printing of one of herschel's importent investigations on polarization and the wave theory of light. He designed a new instrument to project the colored rings onto a screen about three inches behind the analyzer. This method allowed Herschel to examine the details of the tints.

Édition originale ,Nicolas-Louis de Lacaille (1713-1762) est l'un des principaux astronomes français du XVIIIe siècle. Au cours d'une mission dans l'hémisphère sud de 1750 à 1754, il a établi un observatoire au cap de Bonne-Espérance à partir duquel il a observé et mesuré les positions d'environ 10 000 étoiles australes. Près d'un siècle plus tard , l'ensemble des observations de Lacaille est entreprise sous la direction de Francis Baily. Le résultat a été publié en 1847 sous le titre Un catalogue de 9766 étoiles dans l'hémisphère sud.P2-1A
