THE REVISION OF THE ECHINI 107 



have been spent at the Knipe, but there is an improve- 

 ment, I fancy, since father's days ; in fact ladies go there 

 now with their husbands, they having found that their 

 husbands would go and spend their evenings they have 

 determined not to leave them to their own devices, but 

 to lend them the charm of their presence and beer at 

 the same time. 



From Leipzig he writes a few days later : — 



" From Wiirzburg I went to Leipzig, stopping between 

 two trains at Erlangen, a rather round about way, to pay 

 a visit to Ehlers. He came to meet me at the railroad 

 station and, as frequently before, I recognized him at 

 once from his photograph. He took me to his house 

 where we supped and had a pleasant chat of a few hours. 



" I found also there that Ehlers had in his Museum all 

 the original Echini described by Klein, but as it would 

 be naturally a most critical kind of work to identify 

 them all, and would take more time than I can possibly 

 afford, he will send me the whole collection over for 

 examination in the fall. This is for the ' Revision of 

 the Echini' a most remarkable catch, as it will settle the 

 history of many of the old things of the time of Liune."

 and I did not want to get caught, as I had left the Rhine
