TO THE READER. 
The precise words of this old and necessary admission for 
the advancement of knowledge are borrowed from some re¬ 
marks in the Quarterly Review for March, 1822 , on Dobriz- 
lioffer’s Account of the Abipones. The same Number of the 
Review gives a few pages to the first volume of this work also, 
certain animadversions on which Sir Robert Porter’s Editors 
would have thought it proper to notice here, were it not suf¬ 
ficiently apparent to all who have read the volume, and the 
Review, that the Critick (who in such a work cannot be other¬ 
wise than an honourable man,) must have too lightly passed over 
his subject to have been aware of the mis-quotations and inter¬ 
polations presented to him by the amanuensis he had employed 
to select the passages from which he meant to form his opinion 
of the volume. To make another remark on the Review in

question is unnecessary. 
The author, in his Preface, intimates a plan of progressive 
recital, giving accounts of men and things according to successive 
opportunities of observation ; and the reader will find it accord¬ 
ingly executed; subjects being elucidated in this volume, which 
were only glanced at in the preceding; and military and com¬ 
mercial statements respecting Persia and its frontiers particularly 
brought forward. It closes with details concerning the Turkish 
provinces of Valachia and Moldavia ; and a route of posts from 
Constantinople to the Austrian lines.
