When, in November last, I began to make Experimentson Animal Electricity, of which I read someaccount to the Royal Society on the 3d of December; Iwas not only much hurried with business, but could notprocure a sufficient number of Frogs for the purpose. Duringthe last winter and spring, I prosecuted the subjectmore fully and with greater attention; and, on the thirdday of June, I read a second paper to the Royal Society, towhich I have, since that time, made additions.
