accuracy. An exception must be made for the top region of Terevaka, the 

 more important as it rises above all the other hills. We ascended this moun- 

 tain in a gale of wind and in a deluge of rain, making note-taking impossible, 

 and we were soon forced to retrace our steps, especially as illness made me 

 little capable of any serious undertaking. We did not see any other vascular 

 plants than such as we had found below, but there was a notable increase of 

 mosses, mixed with a species of Clado7iia with podetia. As we resolved to 

 return no collecting was done. Unfortunately our ship, the >. Baquedano* of 

 the Chilean Navy, left two days later without giving us a chance to visit the 

 mountain a second time.
