BLAKE — PAST LIFE IN SOUTH AMERICA.

strongly a magnified guinea-pig, all these past forms are ensbriued 

 in our Museums, 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 Palasontology 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 Vii majo7^es of science, "evidence has been creeping in" indi- 

 cative 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- 

 on tologie Fran^aises '), but is only intended to offer a sketch of the 

 principal South American Mammalia. Many of the species entered 

 in this list, will 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 South 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.'
