352 APPENDIX A 



stages the South American fauna consisted largely of types that else- 

 where had already disappeared and that these types persisted into 

 what was geologically a very recent period only some tens of thousands 

 of years ago, when savage man of practically a modern type had already 

 appeared in South America. The evidence we have, so far as it goes, 

 tends to show that the South American fauna always has been more 

 archaic in type than the arctogeal fauna of the same chronological level. 

 To loose generalizations, and to elaborate misinterpretations of 

 paleontological records, the kind of work done by Mr. Haseman 

 furnishes an invaluable antiscorbutic. To my mind, he has estab- 

 lished a stronger presumption in favor of the theory he champions 

 than has been established in favor of the theories of any of the learned 

 and able scientific men from whose conclusions he dissents. Further 

 research, careful, accurate, and long extended, can alone enable us to 

 decide definitely in the matter; and this research, to be effective, must 

 be undertaken by many men, each of whom shall in large measure pos- 

 sess Mr. Haseman's exceptional power of laborious work both in the 

 field and in the study, his insight and accuracy of observation, and 

 his determination to follow truth with inflexible rectitude wherever it 

 may lead — one of the greatest among the many great qualities which 

 lifted Huxley and Darwin above their fellows.
