BLAKE — PAST LIFE IN SOUTH A:MEEICA.

strongly a magnified guinea-pig, all these past forms are enshrined 
in our JNTuseums, or by their restorations ornament our Crystal 
Palace. The object of the present paper is not again to describe 
those animals which the acumen and critical skill of Professor Owen, 
or the sagacity and hardy research of Mr. Dai'win, have unveiled to 
us. South American Palaeontology may well be proud that such 
labourers as these exist to illustrate its phases, or to demonstrate its 
signification. Whilst, however, since the publication of the works of 
these Dii majores of science, "evidence has been creeping in" indi- 
catiA'e of the existence of new and interesting forms of extinct life 
in South America, a rapid glance at some of which has been the ob- 
ject of the preceding paper. 
The following list is founded on that of Gervais (' Zoologie et Pale- 
ontologie Francaises '), but is only intended to off'er a sketch of the 
principal South American Mammalia. Many of the species entered 
in this list, Avill doubtless sink to the rank of mere synonyms ; whilst 
under one name, often many natural species will be comprised. In the 
meanwhile, it will be found useful as indicating the imperfect state of 
our present knowledge, which is caused by the fact that large districts 
of ISouth America are yet unexplored by the palaeontologist or the 
fossil collector. The malevolent influences, which retard the progress 
of physical science in countries colonized by Spaniards or their de- 
scendants, have been well described by the late Mr. Buckle, in the 
second volume of his ' History of Civilization.'
