Publisher's Synopsis
Excerpt from Annales de Chimie Et de Physique, 1906, Vol. 9
Par instants des mouvements se produisent dans l'au rore: les rayons se d�placent le long de l'arc auroral et l'ensemble tourne, tant�t dans un sens, tant�t dans l'autre, autour de l'axe magn�tique du globe. Quelquefois la base des rayons s'�l�ve ou s'abaisse comme si chaque faisceau �tait anim� d'un mouvement longitudinal (danse des rayons).
