PREFACE 
The student who attempts to use "Grevillfca" 
soon discovers that its valuable contents are not 
readily available, owing to it not being suffic- 
iently indexed. It has no specific index of the 
text or illustrations. A topical index appears 
in each volume, except the sixth, in which it is 
missing. These have not been placed in regular 
order. Some are in the front, others in the mid- 
dle, or back of the volumes. To supply this de- 
fect, an index of indexes has been made. Next ap- 
pears a specific index of the illustrations, sup- 
plemented by a tabulated record of the page and 
volume containing the desired information or des- 
criptions of each plate. Without an index, the 
185 plates possess little value, as the inscrip- 
tion under many of them was only that of the coun- 
try in which the specimen or collection was found, 
as "Australian” etc. To gain any information of 
such, the reader was obliged to first search 
through the topical indexes for that particular 
collection, and when there were a number of that 
kind, as was frequently the case, the search must 
be continued through numerous pages of several vol- 
umes &re the desired reference to the plate was 
discovered. When found, a tabiilated record was 
made of the page and volume containing the desired 
information or descriptions of the plates.
