FIELD ZOOLOGY AND GEOGRAPHY 341 



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 favour of the theory he champions 

 than has been established in favour 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 possess 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.
