guages, for nobody will bother to learn Dutch. Besides, that's all I 

 know; my Italian is very rusty and I've clean forgotten my Malay." 

 Rusty, or not, his Italian was still very fluent. 



The principal address, delivered publicly and before a plenary session 

 of the Congress, was by Weissmann, who spoke upon his theories of 

 heredity. He spoke in so low a tone and kept his face so persistently 

 bent over his manuscript, that I caught just a single phrase of the 

 intolerably long discourse. At one of the sectional meetings, at which 

 Weissmann was present, Eimer, of Tubingen, made a violent attack 

 on him. The great Freiburger was not accustomed to that sort of thing 

 and was beside himself with rage. So burning red a human countenance 

 I have seldom beheld, as he left the room, fairly sputtering with wrath, 

 but he made no pubUc reply. 



One of the most interesting of the ceremonial occasions of the Con- 

 gress was the evening public lecture, given by R. Bowdler Sharpe, 

 of the British Museum. The lecture was a full-dress affair, honoured 

 by the presence of the Queen and the Queen Mother. It was the only 

 time I ever saw Her Majesty of Holland, who was then a very attrac- 

 tive child of fifteen, or so. Another and much more agreeable occasion 

 was the diner intime at Scheveningen, given by the Dutch members of 

 the Congress to the foreign visitors. There I met, for the last time, as 

 it proved to be, M. Filhol, who had received me so hospitably in Paris 

 seven years before. He told me that he had recently got hold of the 

 skull of a French fossil rhinoceros, Cadurcotherium, which, as I had 

 suspected, proved to be nearly identical with the American aquatic 

 rhinoceros that Osborn and I had named Metamynodon. 



In November of the same year, the family was completed by the 

 birth of our fifth daughter, Angelina Thayer. 



The Patagonian Expeditions, much the most important scientific 

 enterprise with which I have been associated, were inaugurated by 

 Hatcher's sailing from New York, on February 29, 1896. He took with 

 him his brother-in-law, O. A. Peterson, then on the staff of the Amer- 

 ican Museum, for many years past associated with the Carnegie Mu- 

 seum in Pittsburgh. This expedition came near to bringing about the 

 only misunderstanding that ever arose between Osborn and myself. 

 Sortie months before Hatcher sailed for South America, Osborn told 

 me that he expected to send an expedition to Patagonia, to which the 

 extraordinary discoveries of the brothers Ameghino had directed the 

 attention of palaeontologists the world over. In telling me of this project, 

 Osborn enjoined the strictest secrecy on me, saying that a premature
