NATURE 



[September i, 1923 



Dr. T. F. Wall will describe a new type of induction 

 motor which, although of the squirrel-cage type, has 

 many of the advantages of a shp-ring motor. Prof. 

 jVIarchant will read two papers, one on a method of 

 improving the wave-shape of an alternator, and the 

 other on the triple-frequency currents which occur 

 in the earth-return of three-phase cables. A paper 

 on water turbines is being read by Dr. H. Mawson, 

 and anotlier on the strength of forked connecting rods 

 by Mr. W. J Kearton. 



Section H (Anthropologv). 



Mr. Percy E. Newberry's presidential address to 

 the Section will be on " Egypt as a Field of Anthro- 

 pological Research," and will deal with the origins 

 of Egyptian civilisation, showing that its elements 

 are not all native to the soil. Mr. Newberry will also 

 deal inter alia with aspects of Egyptian culture in 

 opening a discussion on ' The Origin of Domesticated 

 Plants and Animals." A second organised discussion 

 in a joint session with the Geographical Section will 

 deal with " The Place of Man and his Environment 

 in Sociological Studies," to be opened by Prof. J. L. 

 Myres. Sir Arthur Evans will embody, in a con- 

 sideration of " Crete as a Stepping-stone of Early 

 Culture," some extremely important discoveries 

 recently made by him in that island. Mediterranean 

 archaeology will also be represented by two com- 

 munications from Mr. Stanley Casson on " The North 

 iEgean Coast in the Bronze Age " and " Prehistoric 

 Sites in the Dardanelles and Bosporus." 



In British archaeology several papers will deal with 

 Welsh prehistory, including a general survey by 

 Prof. H. J. Fleure, and an account of " The Hill- 

 forts in North Wales and their Historical Rack- 

 ground," by Dr. R. E. Mortimer Wheeler. Prof. E. 

 Ekwall, of Lund University, will discuss "The Early 

 History of Lancashire in the Light of its Place- 

 names." 



In ethnography, Mrs. Scoresby Routledge, in 

 " Mangarevan Folk-lore," will give an account of 

 some results of her recent expedition to the Austral 

 Islands and Mangareva; Mr. E. Torday will describe 

 the methods of native traders in Central Africa, and 

 will give an account of Hungarian folk -music, with 

 instrumental and vocal illustrations. Mr. Torday 

 has also arranged for a band of Hungarian gv'psy 

 rnusicians to perform at an evening soiree. This will 

 give added interest to Dr. John Sampson's paper on 

 " The Origin and Early Migrations of the (gypsies." 

 The Near East will also be represented by Baron F. 

 Nopsca's account of " House-building and House 

 Implements in Northern Albania." Among a number 

 of other interesting communications, space will per- 

 mit mention only of an account of the culture of the 

 stone-using peoples of Central Celebes by Dr. A. C. 

 Kruyt, who has recently returned from an expedition 

 of scientific investigation in that island. 



Section I (Physiology). 



The scope of Section I, comprising, as it does, 

 physiology, histology, experimental pathology, ex- 

 perimental biology, and a good deal of biochemistry, 

 is very wide, as the list of papers shows. The 

 presidential address by Prof. G. H. F. Nuttall, on 

 " Symbiosis in Animals and Plants," is a good ex- 

 ample of this broad outlook. One of the most 

 attractive items on the programme is a lecture on 

 " Insulin and its value in Medicine," by Prof. J. J. R. 

 Macleod, who has been closely associated with this 

 remarkable discovery of the treatment of diabetes, 

 made in his laboratory in Toronto by Prof. Banting 



NO. 2809, VOL. I 12] 



and Dr. Best. On the medical side there are also 

 papers by Dr. S. Monckton Copeman, of the Ministry 

 of Health, on " Diet and Cancer " : by Prof. J. -\I. 

 Beattie, on " The Action of I'inely Divided Particles 

 of Slate, etc., on Toxins " ; by Prof. H. E. Roaf and 

 Dr. F. W. Edridge-Grcfn, on colour vision; and by 

 Dr. M. C. Grabham, • ntal Caries at Porto 



Santo." 



The more academic usuccta of i>l '• re- 



E resented by papers by Prof. H. / r of 



Itrecht, on ' Bioradioactivity and Humoral i-uviron- 

 ment " ; Prof. R. Magnus, of Utrecht, on " The 

 Action of Carbon Dioxide and Adrenaline on the 

 Bronchi and Pulmonary Vessels "; Prof. H. E. Roaf, 

 on " The Analytical Mechanism of the Cx>chlea " : 

 Prof. J. S. Macdonald, and a^llaborators, on the 

 physiology and energetics of walking; ''r"f i s 

 Macdonald and Dr. F. A. Duffield, on thc 

 cost of cycling ; Dr. W. Waller, on the 

 Corpuscles"; and Prof. C. J^vatt Evans, 

 " Contraction of Plain Muscle." 



The more physical and chemical side will take the 

 form of a discussion, with the Chemistr>' 5»ection, of 

 " The Physico-Chemical Properties of Membranes in 

 their Relation to Physiological Science," and papers 

 by Dr. S. C. Brooks (representing the Amencan 

 Association) on " The Electrolytic Conductance of 

 Micro-Organisms " ; Dr. E. B. R. Prideaux, on 

 " Membrane Potentials " ; Mr. T. C. Angus, on "A 

 Recording Katathemometer " ; Prof. W. Ramsden, 

 on " Coagulation of Albumin at Free Surfaces " ; 

 Prof. W. Ramsden and Mr. J. Brooks, on " Factors 

 determining which of Two Liquids form the Droplets 

 of an Emulsion " ; Prof. W. Ramsden, on " Adsorp- 

 tion Films " ; Dr. R. Coope and Prof. W. Ram.sden, 

 on clinical chemical tests; and Prof. H. E. Roaf, on 

 " The Oxygen Content of Methaemoglobin." Some 

 of these will be of the nature of demonstrations, and 

 histology will be represented by a cytological demon- 

 stration by Prof. Charles E. Walker and Miss F. "W. 

 Tozer. 



Section J (Psychology). 



The psychological topics to be discussed this year 

 in Section J are, in the main, similar to those pre- 

 sented last year at Hull. A large number of the 

 papers have a definite and practical bearing on 

 education and industry. Special stress is placed in 

 several papers on the importance of individual differ- 

 ences. This is explicitly so in the presidential address 

 by Mr. C. Burt entitled " The Mental Differences 

 between Individuals — with special reference to Applied 

 Psychology in Education and Industry*." 



The connexion between psychology and other 

 sciences is again clearly shown by the titles of the 

 joint discussions. With Section F (Economics), " The 

 Inter-connexions between Economics and Psychology 

 in Industry " will be discussed ; and an endeavour 

 made to study the psychological factors entering 

 into the economic field. With Section G (Engineer- 

 ing), " Vocational Tests for Engineering Trades " 

 will be described. With Section L (Education), 

 " The Delinquent Child " will be studied — the papers 

 dealing largely with a classification of the com- 

 moner delinquencies according to their psychological 

 nature. 



A glance at the programme shows that there are 

 two topics of great interest both to education and to 

 industrv^ which receive special treatment, namely, 

 (i) vocational guidance and vocational tests ; (2) 

 mental efficiency and fatigue. Important in this 

 connexion will be the results presented by research 

 workers of the National Institute of Industrial 

 Psychology, notably in a paper on " The Conception
