Not infrequently, too, the text and figures are not in agree- 
In the preparation of the following catalogue, the pre- 
liminary work on which was done by Mr. J. C. Bay, while 
he was in the employ of the Garden, considerable use has 
been made of Von Haller's Bibliotheca Botanica, 2 vols., 
1771-2; Meyer, Geschichte der Botanik, 4 vols., 1854-7; 
Eeuss, Repertoriura Comraentationura a Soc. litt. edit., 3 
vols., 1801-3; Sachs, Geschichte der Botanik, 1875; 
Seguierius and Bumaldus, Bibliotheca Botanica, 1740; 
Sprengel, Historia Rei Herbariae, 2 vols., 1807-8, and Ge- 
schichte der Botanik, 2 vols., 1817-8; Warming, Den 
Danske Botaniske Literatur, 1881; Winckler, Geschichte 
der Botanik, 1854 ; and Winther, Literaturae ScientiaeRerum 
Naturalium in Dania, Norvegia & Holsatia, 1829. The 
principal labor of reading proofs and verifying the entries by 
comparison with the works has fallen to Mr. C. E. Hatchings. 
Grateful acknowledgment is also made to the donor of the 
collection for assistance rendered with many obscure titles, 
and for reading and annotating the proofs of the catalogue. 
The intention has been to spell authors' names as on the 
title page of each work, except that oblique cases are uni- 
formly reduced to the nominative. Cross references facili- 
tate the collation of the works of a given author who may 
have published in several languages, modifying his name to 
suit the idiom of each, — a very frequent custom with the 
early writers. Translators' or changed editions are cata- 
logued under the author, with cross references under 
editor or translator. Under each entry the titles are 
aiTanged chronologically, except that all editions of a given 
work under each name come together. Translations or 
editions of works originally published prior to 1753, are 
included in the catalogue, even though of recent publica- 
tion, and though the originals may not be in the library. 
Where several works are bound together, the volume is 
placed on the shelves under the one first found on opening 
it, each of the others being indicated in the catalogue as
