ll PREFACE. 
the names which they bear in it; or to those which 
may have been given to the plants in the best known 
and most standard Botanical publications of the day. 
The arrangement, then, is as follows : we have given, 
I. Aw Eneuisn ALpuaserica Inpex ; 
Il. A Latin Atpuasericar Inpex; and 
III. A Sysremaric Inpex, following the order 
of SPRENGEL, in the latest edition of 
Linnzus’s Systema Vegetabilium. 
The two first will be of essential consequence to 
those who have had their sets bound up according to 
the order of publication; the latter will be useful to 
those, who may wish to bind their sets systematically ; 
or who may wish to see an arranged catalogue of the 
Genera and Species contained in the Work. 
As many years may intervene, before it will be 
necessary to publish another General Index, we have 
added blank leaves at the end of this, for the conve- 
nience of those who wish to continue a Manuscript 
Index ; and although this Index is complete for the 
Old Series, consisting of the first Fifty-three Volumes 
of this Work, several years hence, it may be desirable 
to amalgamate the Old and New Series under one 
General Index ; we have, therefore, provided for such 
a contingency, by carrying the numbers on in nume- 
rical order beyond the Fifty-third Volume; and those 
who possess the whole of the Work will number their 
next Volume Fifty-four, disregarding the distinction 
of Old or New Series, which has been made princi- 
pally to mark a new epoch in the arrangement under 
a new Editor, and to give many an opportunity of 
commencing the Work conveniently, who may not 
have the means of purchasing the former Series.
