examined this substance, some of wliicli is contained in 

 the Berlin Museum (also in Chaldni's collection) micros- 

 copically. He found the whole to consist evidently of a 

 compact smoothed mass of conferva? and about twenty 

 nine well preserved forms of the called infusoria. There 

 were eight kinds of siliceous shells, or bacillariacejB, the 

 others having those which are soft or membranous.. 

 These inlusoria have now been preserved nearly two 

 hundred years. The mass may have been raised by a 

 storm from Courland and was not meteoric, and was 

 merely carried away, but may have also come from a far 

 distant district. The original locality of the substance 

 neither the atmosphere nor America ; but most probably 

 either East Russia or Courland. The forms are cosmo- 

 politan. 



In the Orange specimen I found of course conferva; 

 with the usual fresh water bacillariacese.
