has employed consecutive numbers; in other instances they refer to the 
page of the work quoted, the only exception being in such works as 
Wight’s “ leones,” where the names occur on the plates, and in such 
cases the number is that of the plate. 
The parts of plants or their products, may in some instances take a 
name differing from that of the plant itself. Whenever our authors have 
indicated this we have followed them. We have not, however, attempted 
to supply such indications when absent, nor, as already stated, have we 
in any case assumed the responsibility of altering their names or orthography. 
Alterations of this character formed no portion of our scheme in the 
construction of this Index. 
In its present state we feel assured that the work will have its 
practical and commercial value, not only as a key to the botanical names 
of plants and products of which only a native name is known, hut also 
as an index to sources where further and more explicit information may 
he obtained. 
Throughout its whole preparation the services of Mr. M. C. Cooke 
have been of great value; and on him has devolved the formidable task 
of passing the sheets through the press.
