leads must nearly vanish, therefore he concluded that the parallel connection of such induction apparatus as he had in his mind’s eye was impracticable. The apprehension of Kennedy’s ideas, as we have here stated, finds direct confirmation from the leading article in the “Electrical Review” of 9th June, 1883. At the end of this leader the editors say, that “Mr. Kennedy’s apparatus is an induction coil pure and simple.” “Messrs. Gaulard and Gibbs will scarcely deny, nor can they deny, that the action of this particular construction of the coil is identical with that of his.” In this sentence it is distinctly stated that the construction of Kennedy’s induction apparatus is identical with that of Gaulard and Gibbs’. Kennedy accepted this statement in silence; if it had been otherwise, he would have protested in his next appearance in print. In order to make possible the connection of transformers in parallel, the advantages of which it may be said Kennedy had augured, there was still much wanting. Above all there was wanting the idea of a transformer as meant at present, and an exact knowledge of its action. F. Geraldy has expressed himself very suitably upon this point in the introduction to his report upon the trials made with the system of Messrs. Gaulard and Gibbs.[7] “La distribution de l’électricité comporte la solution d’un grand nombre de problèmes. Il ne suffit pas de se décider en principe et lorsqu’on a choisi la distribution en quantité (en supposant même, que l’un des procédés puisse être appliqué d’une façon exclusive, ce qui n’est pas certain), lorsqu’on a trouvé le moyen de régler le générateur et les recepteurs conformément au mode choisi, il reste encore à lever quantité de difficultés, a créer et disposer beaucoup d’organes auxiliaires.” Geraldy explained distinctly that it was not sufficient to determine only the method of connection, but there were still a considerable number of obstacles to be surmounted before the object could be attained. It has been a costly lesson, before the properties of transformers were known, which make them form a self-regulating system. Even in the year 1884 do we still find Messrs. Gaulard and Gibbs on the same false track as previously. It was in the Turin Exhibition where Messrs. Gaulard and Gibbs carried out their system upon a large scale, and where they also succeeded in gaining the interest of technical circles, and arousing general attention.
