may presume therefore to have been derived from the 

 subjugation of a native species of Bos. 



In this field of conjecture, the most probable one will 

 be admitted to be that which points to the Bos longifrons 

 as the species which would be domesticated by the ab- 

 origines of Britain before the Roman invasion. Had the 

 Bos primigenius been the source, we might have expected 

 the Highland and Welsh cattle to have retained some of 

 the characteristics of their great progenitors, and to have 

 been distinguished from other domestic breeds by their 

 superior size and the length of their horns. The kyloes 

 and the runts are, on the contrary, remarkable for their 

 small size, and are characterised either by short horns, as 

 in the Bos longifrons, or by the entire absence of these 

 weapons. 



ADDENDUM TO 



The valuable geological services rendered to the Russian 

 Empire by our distinguished countryman, Roderick Impey 

 Murchison, Esq., have been the source of reciprocal bene- 

 fit to Zoological science at home, the Emperor of Russia 

 having been pleased, at Mr. Murchison's request, to direct 

 the transmission to this country of the prepared skin and 

 the skeleton of the rare Zubr, or existing Wild Aurochs, 

 which species is preserved with so much care in the forests 

 of Lithuania. The specimens have been presented by 

 his Imperial Majesty to the British Museum, where I 

 have had the opportunity of comparing the recent bones 

 with those of the fossil Aurochs since the foregoing sheets 

 went to press.
