Dr. Jackson also gave an analysis* of a new mineral obtained from 
. Chessy, om which was supposed to be a hydrate of copper; anal- 
ysi er pro roved it to be a crenate of copper instead of the hydrate. 
- For this mineral, , he proposed the name of Beaumontite, in honor of 
M. Elie de Beaumont, the distinguished French geologist. He also 
exhibited specimens in which crenic and apocrenic acid were combined 
with metallic bases. Crystals of crenic acid were also exhibited; 
these were obtained by dissolving the acid in alcohol, and evaporating 
to dryness in the sun. 
Dr. Jackson then read a communication addressed to him by 
Mr. George Catlin, giving an account of his visit to the Coteau des 
_, Pisivies, the locality from whence is obtained the Indian “pipe stone."
