Publisher's Synopsis
Excerpt from Annuaire de la Soci�t� M�t�orologique de France, 1896, Vol. 44
M. LE pr�sident rappelle que la diff�rence d'uction magn�tique des ...mpos�s du fer selon leur natu re, se retrouve �galement dans certains alliages. Ainsi, un alliage de fer et de nickel contenant 23 pour 100 de ce dernier m�tal, est sans aucune influence sur l'aiguille aimanl�e, et l'on cmoeenoe � utiliser cette propri�t� pour la construction de c'ertaines pieces des chronom�tres, mais cette influence appara�t d�s qu'on modifie la proportion de nickel, dans un sens ou dans l'autre.
