[N. S. Vol. XXXIV. No. 



by Dr. Leonard Hill, followed by Professor 

 N. Zunz, of Berlin; and a third on Inhibi- 

 tion, to be opened by Professor C. S. Sher- 

 rington, followed by Mr. Keith Lucas and 

 Professor Macdonald. A report on Anesthet- 

 ics will be followed by a paper on " Additions 

 to the Use of a Chloroform Inhaler," by Pro- 

 fessor A. C. Vernon Harcourt. Among a 

 large number of other papers mention may be 

 made of contributions by Professor Macdon- 

 ald and Dr. J. E. Chapman on " Heat Pro- 

 duction and Body Temperature during Rest 

 and Work " ; Dr. P. W. Edridge-Green, " Fre- 

 quency of Color Blindness in Males " ; Dr. 

 Harriette Chick and Dr. C. J. Martin, of the 

 Lister Institute, on the " Chemistry of Heat 

 CoagTilation of Proteins " ; Dr. H. E. Eoaf , 

 " Some Considerations on the Influence of 

 Hasmoglobin in the Haemolysis of Red Blood 

 Corpuscles " ; Professor H. J. Hamburger, of 

 Groningen, " New Researches on Phagocy- 

 tosis " ; Dr. W. N. F. Woodland, on " Recent 

 Views concerning the Physiology of Gas 

 Production in connection with the Gas 

 Bladder of Bony Fishes," and Dr. John Tait, 

 various papers relating to the frog. An in- 

 teresting exhibit, by Professor C. S. Sher- 

 rington, will be a model to illustrate Listing's 

 law of the movements for the eyeball. 



Professor F. E. Weiss will preside over 

 Section K (Botany). A joint meeting has 

 been arranged between this section and the 

 Geological and Geographical Sections to con- 

 sider the relation of the Present Plant Popu- 

 lation of the British Isles to the Glacial 

 Period. A general discussion on the subject 

 will be opened by Mr. Clement Reid. 

 Another discussion on the Principles of Con- 

 struction of Phytogeographical Maps will 

 probably be opened by Mr. A. G. Tansley. 

 Additional interest will be lent to the pro- 

 ceedings of the section, and to these discus- 

 sions in particular by the presence of a num- 

 ber of the most eminent continental and 

 American plant geographers, who will be in 

 England during August for an "Interna- 

 tional Phytogeographical Excursion to the 

 British Isles." As the neighborhood of 

 Portsmouth offers many attractions from the 



point of view of plant geography, excursions 

 will play an important part in the program 

 of the section. There will again be included 

 in the " indoors " program a semi-popular 

 lecture, which this year will be delivered by 

 Mr. Francis Darwin. Other contributions to 

 the sectional proceedings will include papers 

 on " Phytogeography as an Experimental 

 Science," by Professor Massart ; " The Swiss 

 National Park and its Flora," by Professor 

 C. Schroter ; " Some Petrified Jurassic Plants 

 from Scotland," by Professor A. C. Seward; 

 " Recent Work on Jurassic Plants of York- 

 shire," by Mr. H. H. Thomas ; " A Fifteen- 

 Year Study of Advancing Sand Dunes," by 

 Professor H. C. Cowles, of Chicago ; " New 

 Proposals in Ecology," by Professor F. E. 

 Clements, of Minnesota ; " The Vegetation of 

 Pebble Beaches," by Professor J. W. Oliver; 

 " The Seaweeds of a Salt Marsh," by Miss S. 

 M. Baker ; " The Water-content of Acidic 

 Plants and the Wilting of Moorland Plants," 

 by Mr. W. B. Crump ; " The Morphology of 

 Leguminous Nodules," by Professor Bottom- 

 ley ; " Nuclear Osmosis as a Factor in 

 Mitosis," by Mr. A. A. Lawson ; " Nuclear 

 Division in Spongospora," and " The Poly- 

 phyletic Origin of the Cornacese," by Mr. A. 

 S. Home, and " The Transference of Sugar 

 from the Host Plant to the Parasitic Cus- 

 cula." 



The Agricultural Sub-section is now at- 

 tached to Section K. Its chairman, Mr. W. 

 Bateson, proposes to devote his address to a 

 consideration of the proper scope of an ap- 

 plied science, with special reference to the ap- 

 plication of genetic research to agriculture 

 and horticulture. The program of the sub- 

 section promises a series of most interesting 

 and useful discussions and papers. Reference 

 has already been made to the joint discussion 

 arranged with the Chemical Section. Another 

 discussion on How best the University Agri- 

 cultural Department may come into Contact 

 with the Farmer will be opened by Principal 

 Ainsworth Davis, who will be followed by 

 Mr. R. Hart-Synnot, dealing with the Amer- 

 ican and Canadian systems, and Mr. J. H^
