‎---- Deuxième édition ---- EXEMPLAIRE de Marcel BRILLOUIN avec sa signature sur le titre du second volume COMPORTANT DES NOTES et CORRECTIONS DE SA MAIN dont certaines plus importantes dans le second volume qui a été entièrement interfolié ---- "Closely connected with researches on attraction and elasticity is the development of spherical harmonics... Important contributions were made in Germany... Especially active was E. Heine (1821/1881) of the University of Halle, the author of the Handbuch der Kugelfunktionen (1861, 2nd ed. 1878/1881)". (Cajori p. 470) ---- "His main fields were spherical functions, Lamé functions, Bessel functions and related subjects. His greatest work Handbuch der Kugelfunctionen, was first published in 1861. The second edition (1878/1881) of Heine's book was still a standard compendium on spherical functions well into the 1930's if one considers the frequency with which it was quoted... What Heine did do was to formulate the notion of uniform continuity, which had escaped Cauchy's attention, and to prove the classical theorem on uniform continuity of continuous functions, which could rightfully be called Heine's theorem...".
