Jolts from Volts

Jolts from Volts

I have almost finished my translation of Volta's original article on his pile and his crown of cups.

Most of the article is a straightforward description of his experiments, but I thought I would highlight this rather humorous paragraph, and my translation of it, in which Volta places metal probes in his ears and connects them to his newly invented battery:

  Je n'ai plus qu'à dire un mot sur l'ouie.  Ce sens, que j'avois
inutilement cherché à exciter avec deux seules lames métalliques,
quoique les plus actives entre tous les moteurs d'électricité, savoir,
une d'argent, ou d'or, et l'autre de zinc, je suis enfin parvenu à
l'affecter avec mon nouvel appareil, composé de 30 ou 40 couples de ces
métaux.  J`ai introduit, bien avant dans les deux oreilles, deux espèces
de sondes ou verges métalliques, avec les bouts arrondis; et je les ai
fait communiquer immédiatement aux deux extrémités de l'appareil.  Au
moment que le cercle a été ainsi complété, J'ai reçu une secousse dans
la tête; et, quelques moments après, (les communications continuant sans
aucune interruption,) j'ai commencé à sentir un son, ou plutôt un
bruit, dans les oreilles, que je ne saurois bien définir; c'étoit une
espèce de craquement à secousse, ou petillemont, comme si quelque pâte
ou matière tenace bouillonnoit. Ce bruit continua sans relâche, et sans
augmentation, tout le tems que le cercle fut complet, &c.  La
sensation désagréable, et que je craignis dangereuse, de la secousse
dans le cerveau, a fait que je n'ai pas repété plusieurs fois cette
expérience.

 

  I have nothing more to say except a word on the hearing. The sense that I had vainly sought to excite with only two metal strips, although the most active among all the drivers of electricity, namely, silver, or gold, and the other of zinc, I finally managed to affect with my new apparatus, consisting of 30 or 40 pairs of these metals. I had introduced beforehand in both ears, two kinds of metal probes or rods, with rounded ends, and I made immediate contact with them at both ends of the device. At the time that the circle had been thus completed, I received a jolt in the head and a few moments later (the connections continuing without interruption,) I started to sense a sound, or rather noise in the ears, which I cannot well define; it was a kind of cracking shock, or bubbling, as if some pate or viscous substance were boiling. The noise continued unabated, and without an increase, the whole time that the circle was complete, &c. The unpleasant sensation, and that which I feared to be dangerous, the shock in the brain, has ensured that I have not repeated this experiment many times.
