1858-64.] VISIT AT AIX-LA-CHAPELLE. 81 



to go so far as Berlin, Alexander arranged with his 

 brother Max to meet Agassiz at Aix-la-Chapelle, and 

 from there to go with the whole party for a two-days 

 visit at the house of Max Braun, who was director of 

 the mines at La Vielle Montagne, near Moresnet, 

 Belgium. It was a meeting of congratulation on every 

 side, and Mrs. Agassiz and Pauline were objects of 

 great interest to the two brothers. They found Agassiz 

 the same enthusiast, full of new schemes for the prog- 

 ress of natural history, and they were delighted to 

 learn his success in the foundation of a new museum 

 at Cambridge. The moment of separation, which all 

 realized meant a final farewell, came only too soon, 

 and Agassiz left for Ostende, London, and Liverpool, 

 whence he sailed the loth September for Boston. 



Agassiz took advantage of his stay in Europe to pur- 

 chase palseontological collections for his new museum. 

 He succeeded in obtaining the excellent collection of 

 his old teacher at the University of Heidelberg, Pro- 

 fessor Bronn, of which he had made use when a 

 student there. While in Switzerland he secured col- 

 lections from the rich cretaceous localities of Ste. Croix, 

 Canton de Vaud, of Oeningen and Claris, and in Eng- 

 land he bought splendid Jurassic fossils from the 

 vicinity of Weymouth and Lyme Regis. But it was 

 at Lieges in Belgium that he made the most important 

 purchase, the great collection and the no less great 

 library of Professor L. G. de Koninck, the author of 

 many monographs on the carboniferous fossils. How- 

 ever, the bargain with de Koninck was not concluded 

 until more than a year later.
