Hambleton, Kepwick, and Hawnby tribes, between whom, 
probably, feuds would frequently take place ; so that sites 
which are now almost deserted may have been busy scenes of 
savage polity in pre-Itoman times." 
Finally, from these several interments, we ascertain that 
the Hambleton Hills have been occupied by different races of 
men during a long series of years. The earliest, or long 
barroiv, dating very probably 3,000 years since, the circular 
British barrow not less than 1,800 years ; though the 
Rev. William Greenwell considers that 1,000 years before 
Christ is not too remote a period to assign for the earliest of 
this class, and the latest, or Saxon, from the fifth to the ninth 
century of our era. 
ON THE PLEISTOCENE MAMMALS OF YORKSHIRE. BY WM. BOYD 
dawkins, m.a. (oxon.), f.g.s., etc. (An abstract only). 
In examining with some care the remains of animals 
embedded in caverns, peat mosses, river beds, and other early 
deposits, we find them indicate or point to distinct and widely- 
separate periods of time since their entombment. Some of 
the animals are still living in the district, and others of an 
earlier date no longer occur in Britain, but whose former 
existence is recorded in the early annals of this country. 
Another class embrace species, in addition, of which we have 
no record of their ever having been natives of Europe. To 
the first we apply the term Prehistoric; to the last, Pleis- 
tocene, which is synonymous with the terms Post-Pliocene 
Preglacial, and Glacial. It applies to all deposits or forma- 
tions, from the top of the Norwich Crag up to the prehistoric 
deposits comprising the preglacial, the forest-bed, the glacial 
drift, the post-glacial brickearths, loams, gravels, and the 
contents of the older ossiferous caverns. In some instances, 
species of animals appear to have lived through the earliest of 
these periods down to the present time; while others ceased 
to exist at a very remote epoch, and whose bones are either
