V. On a new Species of Rhinoceros found in the Interior of 
Africa, the Skull of which bears a close Resemblance to that found 
ina Fossil State in Siberia and other Countries. By Sir Everard 
Home, Bart. VPRS. 
“It has been hitherto asserted,” we are informed in the com- 
mencement of this paper, “(as one of the most curious circum- 
stances in the history of the earth, that all the bones that are 
found in a fossil state, differ from those belonging to animals 
now in existence; and I believe that this is generally admitted, 
and that there is no fact upon record, by which it has been abso- 
lutely contradicted; but the observations [ am about to state 
respecting this rhinoceros, illustrated by the drawings that 
accompany them, will go a great way to stagger our belief 
upon this subject.” 
“« The skull of the animai belonging to this new species of 
rhinoceros, now living in Africa, was brought to this country by 
Mr. Campbell, one of the missionaries sent. there from the Lon- 
don Missionary Society, and is deposited in their Museum in the 
Old Jewry.” 
Sir Everard then proceeds to give, from Mr. Campbell’s memo- 
randa, an account of the locality and habits of the animal, but 
as the substance of these has already appeared in various publi- 
cations, we shall pass to the description of the skull. This is 
shown, with the assistance of two engravings, “ to bear so close 
a resemblance to the fossil skulls from Siberia, as to leave no pro- 
minent characteristic mark between them ;” whence the author 
is led to believe, “ that although many animals belonging to 
former ages may be extinct, they are not necessarily so: no 
change having taken place in our globe, which had destroyed 
all existing animals, and, therefore, many of them may be actu- 
ally in being, although we have not been able to discover them.” 
After arguing from the existence in Africa of immense tracts of 
country yet unexplored, that “ we have no right to assume that 
large animals, although not met with, do not exist;” he gives 
the following particulars of the migration of an animal of another 
_ kind, as explaining “ in what way particular animals may elude 
our ey at one time, and at another be brought within our 
reach.” 
“ Mr. Campbell says, he found that the wild ass or quagga, 
migrates in winter from the tropics to the vicinity of the Malale- 
veen river, which, though further to the south, is reported to be 
warmer than within the tropic of Capricorn, when the sun has 
retired to the northern hemisphere. He saw bands of 200 or 300, 
all travelling south, when on his return from the vicinity of the
