   This little work is offered as a pocket com-
 panion to those who having studied the ele-
 ments of Botany, wish to bceome acquainted
 with the many beautiful and interesting native
 plants, they may meet with  in their walks,
 and  facilitate their researches in  more volu-
 minous works.  If it should also serve to assist
 the memory of the more erudite  Botanist,
 when on excursions wherein from  their  size,
 he might be deprived of the use  of bocks  of
greater importance, the intention of the com-
piler will be  completely answered \ his  only
•Jesire being to be useful.

POETICAL WORKS
   SIR WILLIAM JONES,
WITH THE LIFE OF THE AUTHOR.
  The splendid talents of Sir W. J. arc so
well known that it would be superfluous to en-
ter into  any observations upon  them here.
His Poetical works have been thought worthy
of a place in the late collections of  the best
English  bards.  It has been thought that a
neat edition of his poems,  would be a very ac-
ceptable present to the lovers of polite litera-
ture in this country, and serve to  improve the
taste of the rising generation.—An account of
the life of the author  abridged from the large
work of Lord Teignmouth is prefixed to this,
edition ;  to which will be added several pieces'
not to be found in the London edition.
  If sufficient encouragement  should offer it(
will be put to press immediately ;  to be print j
ed on a fine  paper and  bound handsomely in!
calf and gilt.  Price S 3W to Subscribers—
To Non-Subscribers the price will be advan-
ced.
