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.
