the principal types of Palceolithic and Neolithic objects. Par- 

 ticularly useful is the account of the various Bone-caves that 

 have been found in Britain from time to time. Two of the 

 illustrations are here reproduced throuijii the kindness o( the 

 Trustees of the British Museum. The first is an engraving^ 

 of a horse's head on bone, from C'resswell Crags, Derbx'shire, 



and is o'i Palaeolithic Age. The second represents a peculiar 

 type of Neolithic arrow-head, showing parallel or ' ripple ' 

 flaking. Implements of this type are exceedingly rare in 

 Britain, and appear to be confined to the neighbourhood of 



Bridlington. 



'THE BIRDS OF YORKSHIRE.' 



We would like to draw particular attention to one of the most 

 important works yet undertaken by the Yorkshire Naturalists' 

 Union, viz., 'The Birds of Yorkshire,' by T. H. Nelson, 

 M.B.O.U., with the assistance oi \V. Eagle Clarke, F.L.S., 

 M.B.O.U., and Mr. Fred Boyes. 



The scope of the work will be comprehensive, and the 

 account of each species will include succinct accounts of dis- 

 tribution, faunistic status, migration, nidification, variation, 

 vernacular nomenclature and folk-lore, with full details v\ hen 

 necessary, and critical and detailed particulars of the occurrence 

 of the rare species ; while under each species will be incorporated 

 a verbatim reproduction oi the account given of it by Mr. 

 Thomas Allis, in 1844, whose list (the earliest Yorkshire one) of 

 that year has never been published. 



Illustrations will be included of noted bird-sites or haunts, 

 and interesting phases of bird-life within the county, the number 

 of which will depend upon the amount oi the subscription list. 



The work will be shortly issued, and intending subscribers 

 should send in their names at once to the Secretary of the Union, 

 at The Museum, Hull, from whom a detailed prospectus can be 



obtained.
