248 BOTANICAL GAZETTE. 



Prof. J. G. Lemmon has read before the California Academy of Sciences a 

 very interesting paper upon his discovery of the potato in Arizona, noticed 

 before in these pages. Professor Lemmon's supply of potatoes has been ex- 

 hausted, but he is off again to the Huachuca Mountains this fall for a fresh 

 supply, which various cultivators will experiment upon. 



Baron Felix Thumen has ottered his rich Mycologic Herbarium for 

 sale. In all it probably contains 20,000 species, from all parts of the world ; 

 many of them types, and most of them bearing the labels of the most distin- 

 guished mycologists of this country and Europe. The " Mycotheca Univers- 

 alis " is to be continued. Baron Thumen can be addressed at Vienna, Wlih- 

 ring, Schulgasse 1.
