About This Book

The work presents a concise survey of electrical and galvanic phenomena, opening with a historical overview and moving through core definitions, experimental apparatus, and demonstrable laws. It distinguishes conductors and insulators, describes machines and instruments, and treats sparks, the action of pointed bodies, attraction and repulsion, Leyden jars, batteries, the electrophorus, and electrometers, connecting each topic to illustrative experiments. Historical notes accompany procedural descriptions, references point to further reading, and the text aims to teach foundational principles clearly while guiding readers who wish to pursue more extensive study.

RECOMMENDATIONS.

Having perused this Epitome, it appears to me to comprise, in a concise and perspicuous manner, the principal discoveries that have been made in Electricity and Galvanism, illustrated with a variety of amusing experiments; and I have no doubt that it will prove useful and entertaining to those who wish for information on these subjects.

Professor of Natural Philosophy, and Provost
of the University of Pennsylvania.

Having read, at the request of the authors, a work under the title of “An Epitome of Electricity and Galvanism,” I am of opinion that it is well calculated for the instruction of youth; and also that it may prove a useful manual to gentlemen who wish to acquire, without extensive reading, a general knowledge of the subjects discussed.

Professor of Natural Philosophy and Chemistry
in the College of New-Jersey.

The Epitome of Electricity appears to me to contain a concise, but perspicuous and correct statement of the laws of that branch of Philosophy, and an interesting collection of facts and experiments, by which they are illustrated.

JEREMIAH DAY,
Professor of Mathematics and Natural Philosophy.

Yale College, Nov. 25, 1809.

[As the authors could not transmit to Professor Day a copy of the Epitome of Galvanism, without unduly delaying the publication, his testimonial, of course, refers only to the Epitome of Electricity.]
