FOLIO EDITION OF SHAKSPEARE.

* * * * *

SPECIMEN COPIES of the First Volume of this Work may be seen at MR.
SKEFFINGTON'S, 192. Piccadilly, and at MR. RUSSELL SMITH'S, 36. Soho
Square, London.

The Editor having, at a great sacrifice, adhered to the original limit, and
the estimates having been considered exceeded, has been compelled, to avoid
incurring an extravagant loss, to make the terms very absolute, and to
raise the Subscription to the later copies. Notwithstanding, therefore, the
great demand for the Work, a few copies may still be secured by early
written application.

All communications on the subject are request to be addressed to--

J. O. HALLIWELL, ESQ., AVENUE LODGE, BRIXTON HILL, SURREY.
