Section H (Anthropology). — In this section the pro- 

 ceedings promise to prove as interesting as usual, and 

 quite a large number of the communications are likely to 

 give rise to considerable discussion. One of the most 

 important items in the programme will be a discussion 

 on the head-form of the prehistoric and early historic 

 races in Britain which has been arranged to take place in 

 connection with an exhibit of British crania, now in the 

 possession of the Yorkshire Philosophical Society, and 

 crania from Laver Hill. The discussion will be opened 

 by Mr. J. Gray with a paper surveying the evidence, 

 anthropological and collateral, bearing on the affinities 

 and probable origin of the prehistoric and early historic 

 races which have settled in Britain. Dr. F. C. Shrubsalt 

 has also promised to contribute, and Dr. W. Wright and 

 others will take part in the discussion. In this connection 

 considerable interest attaches to a paper on the relations 

 between archaeological and anthropographical data in the 

 ethnology of Scotland by Dr. T. H. Bryce, and a paper by 

 Mr. J. R. Mortimer on the relation between stature and 

 head-form in the skeletal remains found in the round 

 barrows of Yorkshire, based on data obtained from his 

 own collections at Driffield. Mr. H. Brodrick will describe 

 a skeleton recently discovered in Scoska Cave, Littondale. 

 Two communications by Dr. W. L. H. Duckworth will 

 deal respectively with a rare anomaly in human crania 

 from Kawiawata Island, New Guinea, and observations on 

 a eunuchoid subject in the Cambridge Anatomy School. 

 Dr. C. S. Myers contributes, as an addendum to the report 

 of the committee on anthropometric investigations among 

 the native troops of the Egyptian Army, and notes on the 

 distribution of cephalic and nasal indices in different 

 provinces of Egypt. 



In general ethnography communications are hardly as 

 numerous as usual. Dr. Haddon will contribute a paper 

 on the ethnology of South Africa, based principally on 

 material collected during the visit of the association to 

 South Africa last year, and Mr. S. Dornan, a South 

 African member, sends a communication dealing with the 

 Bushmen of Basutoland. Messrs. T. A. Joyce and E. 

 Torday jointly will contribute a paper on the Ba-Yakka. a 

 tribe in the Congo Free State. Among papers dealing with 

 points of a more detailed character. Dr. Rivers offers, as 

 a possible explanation, alternative, at least in India, of 

 the importance of the maternal uncle among primitive 

 races, a survival in the marriage customs of southern 

 India, and an account of the astronomy of the Torres 

 Straits islanders. Mr. H. A. Rose will contribute a paper 

 on the custom of female infanticide in India, and Prof. 

 Ridgeway will deal with the origin of the fiddle and 

 guitar. Dr. T. H. Bryce and Mr. Newberry, of the 

 Glasgow School of Art, will exhibit a number of examples 

 of the " door-step " art — designs used by peasants to 

 decorate their door-steps and dairy and kitchen floors in 

 Scotland, which present many interesting features. 



In archreology. Prof. W. M. Flinders Petrie will give 

 an account of a Hyksos fortress and other discoveries in 

 Egypt in iqo6 ; Dr. R. C. Bosanquet will describe his 

 excavations in Sparta, and a communication from Mr. J. L. 

 Myres will deal with early traces of human types in the 

 ^gean. Mr. D. G. Hogarth hopes to communicate an 

 account of the treasures of the primitive .Artemisia of 

 Ephesus, should the interval before the meeting be sufficient 

 to allow an examination of the objects from the site, which 

 have only just arrived in England. Major P. M. Sykes 

 will exhibit a collection of bronze weapons and implements 

 from Persia, which are discussed in a communication by 

 the Rev. Canon Green well. Dr. T. Ashby will read 

 papers on the recent excavations in the Forum, and the 

 excavations at Caerwent in 1904-6. Prof. R. S. Conway
