IV 



The proportion of the original Hunterian specimens of Mam- 

 malian and Avian fossils to those subsequently added to the Col- 

 lection of the College is so small, that the whole are incorporated in 

 one system of arrangement and marked by consecutive or running 

 numbers ; the original specimens, 330 in number, being specified as 

 Hunterian ; the additions by the name of the Donor ; or, when ob- 

 tained by purchase at the sale of a museum, by the name of its 

 Founder. 



With many fossils of extinct species the corresponding part of the 

 nearest allied existing animal has been placed in juxtaposition, and 

 such parts bear the same number as the fossils they illustrate, with an 

 added dot, as No. 2, No. 2" ; No. 1579, 1579\ 



Ten Plates are subjoined to the present Volume in illustration 

 of some of the rarest fossil specimens, which have not before been 

 figured in any Work.
