The town of Volcano, where these specimens were collected, is rich in 

 caves, presenting the most singular formations I have ever witnessed ; and 

 which will at some future day divide the interest now felt in the gigantic 

 trees and stupendous waterfalls, whose grandeur marks them as wonders of 

 the world. 



Owing to the want of time, I have been prevented from pursuing my 

 exploration as much as I could wish ; but should the opportunity occur 

 at any future time, I will give you the result of my discoveries. I hope 

 that the accompanying specimens will prove interesting to you. 



Yours truly, 



J. H. WARWICK.
