nce has been obtained from eminent
scientific men: and the Editor has the satisfaction of announcing among the
Contributors to the first year's volumes the names of Professor Owen, of
the Royal College of Surgeons; Sir William Jardine, Bart.; Professors
Ansted and Tennant, of King's College; the Rev. Walter Mitchell, of St.
Bartholomew's Hospital; and Professor Young, Examiner in Mathematics at the
University of London. Every confidence, therefore, may be placed in the
publication, as regards its soundness of principle, its extent of
information, and its accordance with the results of the latest researches
and discoveries.

During the first year either three or four volumes will be completed. The
respective subjects will not be issued in consecutive weeks; but the paging
of each series will be continuous:--so that the whole, when collected at
the end of the year, will form separate Volumes, with Title-pages,
Prefaces, Tables of Contents, Indices--each Volume being a distinct work on
Natural Philosophy, on the Two Great Divisions of Natural History, and on
the Mathematical Sciences.

The "Circle of the Sciences" will thus, by the aid of copious Analytical
Indices, combine all the advantages of an Encyclopaedia, as a work of
reference, without the irksome repetition which alphabetical arrangements
necessarily involve.

On the 1st of December an Introductory Treatise,

"On the NATURE, CONNECTION, and USES of the GREAT DEPARTMENTS of HUMAN
KNOWLEDGE."

Will be issued; but the Publication of the Work itself will not commence
until January, 1854.

"Orr's Circle of Sciences" can be supplied by every Bookseller in the
Kingdom; of whom a detailed Prospectus, containing Specimen Page and List
of Subjects, may be had.
