X PATAGONIAN EXPEDITIONS. 



In Buenos Aires, the late Dr. C. Bergh, then Director of the Museum, 

 and Sr. R. Pendola, Secretary, were extremely courteous and provided 

 every facility that the Museum could offer. The United States Minister 

 to Argentina, Hon. William P. Lord, also interested himself in the enter- 

 prise and assisted it in every way that he could command. 



The editor wishes also to express his sense of gratitude to the many 

 collaborators, both at home and abroad, who have taken part in the 

 laborious task of describing the various parts of the collections which 

 have been entrusted to their hands. To their scientific colleagues the 

 names of these collaborators are a sufficient guarantee of the quality of 

 the work. 



Finally, most grateful mention must be made of the generosity of 

 J. Pierpont Morgan, Esq., who has rendered it possible to publish these 

 reports in a manner altogether worthy of their subject and with adequate 

 illustrations. Scientific undertakings of this magnitude are generally 

 executed by governments and are beyond the scope of universities. 

 Mr. Morgan's liberality alone has put it in our power to bring together 

 in one uniform series all the great and varied results of Mr. Hatcher's 

 labors in South America. In expressing his most sincere thanks for this 

 great gift, the editor acts as spokesman for a numerous and widely spread 

 body of students, as well as for Princeton University.
