41 8  International  Botanical  Congress.  {^ptSeMooS1* 
In  the  afternoon  the  Nomenclature  Conference  organized  in  the 
hall  of  the  Museum  in  the  Botanical  Garden  by  electing  as  President, 
Flahault ;  as  Vice-Presidents,  Rendle  and  Mez  ;  and  three  secre- 
taries ;  received  the  report  of  the  standing  committees  and  of  the 
Rapporteur-General  (Briquet) ;  and  adopted  rules  of  procedure. 
The  report  of  the  Commission  was  presented  as  a  quarto  of  160 
pages,  having  the  text  of  the  code  of  1867  in  the  first  column,  the 
new  formal  proposals  of  various  bodies  in  the  second,  notes  by  the 
Rapporteur  in  the  third,  and  the  text  recommended  by  the  Com- 
mission in  the  fourth.  This  texte  synoptique  was  the  work  of  Briquet, 
whose  arduous  labors  for  the  past  five  years  thus  made  possible  the 
revision  of  the  rules  of  nomenclature  by  this  Congress.  His  untiring 
industry,  unfailing  patience,  uniform  courtesy  and  impartiality,  as 
well  as  his  linguistic  facility,  won  the  admiration  of  all. 
Afternoon  sessions  thereafter,  from  3  to  7  or  even  later,  were  de- 
voted to  the  discussions  and  actions  of  the  texte  synoptique. 
Morning  sessions  and  on  some  days  also  afternoon  sessions,  which 
were  held  in  the  lecture-room  of  the  Engineer-Architects'  Club,  were 
devoted  to  addresses  upon  special  topics.  Thus  on  Tuesday  there  were 
six  papers  on  the  development  of  the  European  flora  since  the  Ter- 
tiary period ;  two  introductory,  on  the  geographical  problems  by 
Peack  (Vienna)  and  the  botanical  problems  by  Engler  (Berlin),  while 
Andersson  (Stockholm)  spoke  specially  for  the  Scandinavian  penin- 
sula, Weber  (Bremen)  for  the  North  German  lowlands,  Drude 
(Dresden)  for  the  mountainous  region  of  central  Germany,  and 
Briquet  (Geneva)  for  the  alpine  region. 
On  Thursday  the  topk  was  the  present  position  of  the  doctrine  of 
photosynthesis,  Molisch  (Prag)  speaking  of  photosynthesis  in  chloro- 
phyllous  and  Hueppe  (Prag)  in  chlorophyll-free  organisms,  Kasso- 
witz  (Vienna)  giving  a  short  talk  on  photosynthesis  from  the 
standpoint  of  metabolism.  After  a  brief  intermission  the  general 
problems  of  regeneration  were  discussed  by  Goebel  (Munich),  Lo- 
priore  (Catania)  presenting  a  more  special  paper  on  the  effects  of 
wounding  on  regeneration  of  stems  and  roots.  In  the  afternoon 
there  were  papers  by  Arthur  (Lafayette)  on  the  classification  of 
the  Uredinales ;  by  Istvanfi  (Budapest)  on  the  life  history  of  Botrytis 
cinerea,  and  by  Pettkoff  (Sofia)  on  the  algal  flora  of  Bulgaria. 
On  Friday,  Scott  (Kew)  spoke  on  the  fern-like  seed  plants  of  the 
carboniferous  flora ;  Lotsy  (Leiden)  on  the  influence  of  cytology  on
