EDWARD AUGUSTUS KENDAL.
Embellished with Copper Plates designed and engraved by
SECOND EDITIONCorreeted and much enlarged.
J. HARRIS, SCATCHERD AND LETTERMAN, PEACOCK
IN presenting the public with a new impression of the PockET ENCYCLOPEDIA, the editor, into whose hands it has now fallen, thinks it right to notice the additions which have been made to it. The quantity of letter press is increased full a third ; much of the original matter has been obliterated, to make room for other subjects that were deemed more useful and interesting. The former edition was composed chiefly with a view to Polite Literature and the Arts; in the present is combined a vast quantity of materials connected with the Sciences properly, so denominated.
In Natural Philosopby, a variety of articles will be found in their respective places, such as Electricity, Hydraulics, Hydrostatics, Magnetism, Mechanics, Optics, Pneumatics, and Voltaism. These bave been explained and illustrated with many well-engraved plates.
A brief introduction to Chemistry will be found under the proper term, connected with the articles Chemical Apparatus, Distillation, Hydrogen, Laboratory, Metals, Mineralogy, Oxygen, &c. .
