336 REPORTS ON THE STATE OF SCIENCE, ETC. 



Bone. — A 'toggle,' or dress-fastener; two polishing-bones ; modelling-tool; 

 two tibipe, with perforations and sawn notches ; a highly polished length of 

 bone of quadrangular cross-section. Perforated boar's tusk. Large number of 

 animal remains. 



Pottery. — In some quantity, including a large number of parts of pots finely 

 ornamented ; two pieces of pot covers ; fragments with perforated bases ; and the 

 pedestalled base of a vase. 



Baked Clay. — Triangular loom-weight; fragment in the form of the end of 

 a model boat, with two perforations. 



Spindlcwhorls. — Several of stone, pottery, baked clay, and bone, including 

 an ornamented specimen (very few ornamented exariiples found previously). 



Flint. — A barbed and tanged arrowhead, several scrapers, and small pieces of 

 worked Hint. 



Querns. — Stones of saddle querns. 



Derbyshire Caves. — Report of Committee (Sir W. Boyd Dawkins, 

 Chairman; Mr. G. A. Garfitt, Secretary; Mr. Leslie Armstrong, 

 Mr. E. N. Fallaize, Dr. R. E. Marett, Mr. H. Peake, Prof. 

 W. M. Tattersall) appointed to co-operate with a Committee of 

 the Royal Anthropological Institute in the Exploration of Caves in 

 the Derbyshire district. 



During the season 1921-22, members of the Committee have conducted or 

 supervised explorations in Derbyshire caves at Cresswell Crags, Gressbrook 

 Dale (especially at Ravencliffe Cave), Longcliffe Crags (Harborough Cave), 

 near Brassington, four caves in Hartle Dale, near Castleton, and the 'Demon's 

 Dale ' in the Taddington area. Arrangements have been made for further 

 excavation of this cave, where only the upper layers have been examined 

 hitherto. For a preliminary report by Mr. Storrs Fox see Proc. Soc. Ant. Lond., 

 II, xxii, 129 (1908). A chance discovery of human and animal remains at 

 Castleton led to the examination of a collapsed cave by Messrs. L. Armstrong and 

 R. V. Favell. A fuller report of this year's work will be published in Man. 



Experimental Studies in the Physiology of Heredity. — 



Final Report of Committee (Dr. P. P. Blackman, Chairman; Miss 

 E. E. Saunders, Secretary; Professor W. Bateson, Professor 

 Sir F. Keeble). 



DtraiNG the past year the work on the surface anatomy of the higher plants 

 which wa.' begun in 1921, and briefly reported at the Edinburgh meetins of the 

 Association, has been continued and extended. Examination of the seedlings of 

 various species employed in certain breeding experiments and of other material 

 has yielded evidence supporting the view put forward originally by Hofmeister 

 and Naegeli that the stem must be regarded as consisting of an axial core sur- 

 rounded by a foliar skin. A full account of the observations and the deduc- 

 tions therefrom appears in the April issue of the Avnals of Botany. 



Further breeding experiments have been carried out on Maithiola with the 

 object of ascertaining whether other linkages, in addition to those already 

 described, exist between the several factors which have now been identified, but 

 these results are not yet complete. It is proposed to continue the work, and 

 it is hoped that sufficient financial assistance from another source will be 

 available in the coming year to enable tliis to bp dpiie. The Committee do not 

 ^l^erefore seek reappoin|;i)ient.
