SEPTEMBER 24, 1897. ] 
tivity and interest which centered in the 
Botanical Section were largely due to the 
able and energetic manner in which the 
President conducted the workin hand. To 
the botanists of the United States, however, 
is also due no small credit for their share 
in this happy result. The determination 
had evidently been reached on their part 
to make the botanists of Great Britain feel 
that, although they were to be within their 
own domain during the progress of the 
meeting, there is a brotherhood in science 
which ignores all geographical and political 
limitations, and that on these grounds the 
most cordial sympathy and support should 
be extended. This was made evident not 
only in the very fortunate arrangement 
whereby the Botanical Society of America 
met at Toronto instead of at Buffalo, and 
concluded its proceedings as the work of 
the British Association began, but also in 
the fact that the majority of the botanists 
in attendance were Americans, and that a 
very large proportion—about one-half—of 
the papers presented were from the same 
source. 
The Section met under the very able 
presidency of Professor H. Marshall Ward, 
of Cambridge, England, who was supported 
by Professor D. P. Penhallow, of McGill 
University; Dr. W. G. Farlow, of Harvard, 
and Professor F. O. Bower, of the Uni- 
versity of Glasgow, as Vice-Presidents. 
The attendance was not large, although 
representative. Of English botanists only 
eight were present, including, in addition 
to those already named, Mr. A. C. Seward, 
of Cambridge; Professor F. Weiss, of 
Owens College, Manchester; Professor J. 
B. Farmer, of the Royal College of Science, 
London ; Mr. Harold Wager, of Leeds, and 
Professor J. R. Green and Miss D. F. M. 
Berts, of Cambridge. 
Among those representing American 
botany were noted: Dr. W. G. Farlow, Dr. 
Britton, Dr. Coulter, Professor Barnes, Pro- 
SCIENCE.

fessor Penhallow, Dr. Galloway, Dr. T. J. 
W. Burgess, Dr. Bessey, Dr. Arthur, Mr. 
Webber, Professor Green, Mr. Jeffrey and 
others. Exceptional interest was added to 
the proceedings by the presence of Professor 
P. Magnus, of Berlin, who also contributed 
a valuable paper ‘On the Mycelium of a 
Witches’ Broom Fungus’ and otherwise 
assisted in the work of the Section. 
There were twenty-one papers in all 
presented to the Section, representing 
original research in nearly all the numerous 
branches of botanical science. These con- 
tributions were, in most cases, of a notable 
character, and drew forth animated and 
valuable discussions. The report submitted 
by Professor Farmer, respecting certain in- 
vestigations on the ‘ Fertilization of the 
Pheeophyceze’ conducted under his super- 
vision, already indicates that new and im- 
portant facts bearing upon the relationships 
of this group have been obtained. The in- 
vestigations continue for another year 
under a renewed grant from the British 
Association. 
Mr. Harold Wager gave an account of 
some recent studies of the yeast plant and 
other species of Saccharomyces, with re- 
spect to the presence of a nucleus and its 
constitution in various stages of develop- 
ment. The nucleus in yeast has been a 
subject of study for the past six or eight 
years, and its presence, as demonstrated by 
some seventeen observers, is abundantly 
confirmed by the results obtained by Mr. 
Wager. The author has not been able to 
reach final conclusions respecting the ques- 
tion which has been for some time in con- 
troversy as to whether the nucleus possesses 
a nucleolus or not, but his researches tend 
to the belief that certain granular bodies in 
constant association with the nucleus, and 
which present very different conditions of 
aggregation at various stages of growth, 
may represent the nucleolus. It was fur- 
ther shown that, in the process of budding
