494 BOTANICAL GAZETTE [DECEMBER 
It seems a bit invidious to distinguish the other volume as Résultats scien- 
lifiques; but it may pass as a conventional title. The four hundred odd pages 
are occupied by the formal addresses, and papers volunteered for the Congress, 
twenty-six in number. They are therefore of unequal quality and of different 
character. Some are general summaries of the present status of important 
divisions of botanical science; others are special and technical. Only one comes 
tom America—‘‘A classification of Uredineae based on structure and develop- 
ment,” by Dr. J. C. ARTHUR—and this is translated into German. The only 
English pages are those of Dr. D. H. Scort on “The fern-like seed-plants of the 
carboniferous flora.” A good index makes available the entire contents. The 
two volumes should be in every botanical reference library.—C. R. B 
Knuth’s Handbook. 
In 1899 the first volume of KNutH’s Handhuch der Bliitentologie appeared,3 
based on HERMANN MUILER’s Die Bejfruchtung der Blumen durch Insekten. 
It is general and deals with the structure of flowers and of insects in relation 
to pollination. In the same year the second volume appeared,+ giving an account 
of all known observations upon the pollination of the flowers of arctic and tem- 
other than Europe. The Clarendon Press has undertaken the publication 
of an English translation, the first volume of which has lately appeared,5 and the 
second volume is announced as being in press. The translator is J. R. Atns- 
worTH Davis, Trinity College, Cambridge, and the prefatory note is by Pro- 
fessor I. B. BaLrour. 
The character of this encyclopedic work is well known to students of pollina- 
tion, and it is a great boon to English and American botanists to possess it in 
an English translation. The original text appeared ‘in instalments, and the 
appendices of supplementary information have been incorporated in :he body 
of the text by the translator. A special feature of the translation is the bringing 
together in one list all the citations in the original, and completing the record 
to January 1, 1g04. The number of citations is almost beyond belief, the botan- 
ical titles in the bibliographical list reaching 3748. It must be said, however, 
that the citations are probably more numcrous than significant, as a cursory 
examination suggests. There are frequent cases where “fertilization” is con- 
fused with “pollination,” and papers cited which can hardly be imagined as 
belonging to the real literature of pollination. Then too, there is occasional 
duplication of titles, as for example titles 633 and 643, which are identical in 
every particular. The dreadful task of editing such a mass of citations should
