Descrizione

The first and second editions of this little book being so rapidly disposed of the sale of over copies is sufficient evidence that a want existed for such an inexpensive little work, not only by amateur electricians to whom the treatise was originally addressed, but by professed engineers and mechanics at home and abroad, who have by its aid made their own dynamos to light their dwellings or workshops. The patrons of the former editions included amateurs of rank as well as hard working mechanics, while several letters expressive of delight have reached the Author, for which he takes the present opportunity of returning his thanks,' and for the support accorded to the two past editions. That the instructions were carefully worked out by experiment before being printed, an extract from an Engineer's letter appearing on page 11 will confirm.
