mineral and the label describing its location more distinctly. 
it is crystalized and its colours are deep purple almost black. 
Dr. Hunt of Northampton, furnished the specimen two years

4. Black Oxid of Manganese.—Respecting the locality of 
this mineral, mentioned on page 54 of this volume we have 
received some additional particulars from Mr. Calvin Pres- 
eott, (in the other memorandum, called my misnomer Cal-

undertaken.

Will it afford yourself or Dr. Ives any pleasure to see a 
specimen of the genuine plant with which the Indians per- 
form the cure of the Rattle-snake bite—it is perhaps well 
known to you ?—I have, however, preserved some stalks,

will only enable me to know it again when I see it. It re-
