Sire, Je prie Votre Majestt de daigner agrter la dtdicace de ce livre comme un faible ttmoignage de ma profonde reconnaissance. Vous avez t6 le premier d encourager mes travaux. Apres avoir assist, en 1872, d mes experiences sur les courants secondaires, au Con servatoire des Arts-et Metiers, Votre MajesU a bien voulu, en, honorer deux fois de sa visite mon laboratoire de la rue de la Cerisaie, dans ce quartier du vieux Paris, ob les noms d Henri IV et de Sully sont encore vivants. Cent soixante ans auparavant, Pierre le Grand venait y habiter Jhdtel Lesdiguieres, et, vers la 9 fin du dernier stecle, tillustre Franklin assistait, dans Fhdpital des Ctlestins, a des experiences d Electricity La presence, dans ces mSmes lieux, de Votre Majestt poursuivant son enqufae sur tons les progres utiles a f humanity ajoutera une nouvelle page a nos anciennes traditions et un prtcieux souvenir qui sera conservd.

The fifth part embraces the description and study of the effects of a new apparatus, by means of which we have tried to transform, in the most complete manner possible, dynamic into static electricity, and which we have distinguished by the name of rheostatic machine. The sixth is devoted to a concise enumeration of analogies which the electrical phenomena particularly those which we have noticed with currents of very high tension present with effects produced by mechanical actions, and to the inferences drawn from them as to the nature of electricity. The reader who will only admit absolute deductions from facts, may omit the fourth part, in which induction has considerable play. Nevertheless, we thought we ought not to pass over in silence some of the ideas which the results of our experiments presented, and the real or apparent analogy which they show with natural phenomena. Authors are often blamed for not having understood the inference to be drawn from facts which theyhave observed, or for not having perceived the theoretic sequence, and the applications to which it may lead. We have sought to be free from this fault, which, besides, has not always foundation for it is rare for anyone who has patiently studied nature, seeking new facts, not to also meditate upon their significance, and, as nature is seen complete in each one of her manifestations, it is difficult for the student to avoid being led to generalise the result of his observ ations...
