NOTICE OF NATIVE IRON FROM PEN YAN, YATES COUNTY, 

 NEW YORK. By Thomas G. Clemson. 



On the farm of Mr William Rouse of the above locali- 

 ty, there is found native iron, a specimen of which was 

 sent rae by this gentleman for examination. 



'^The rocks that are found upon this place are sand-

The filtered ammoniacal solution was evaporated to

 the presence of nickel or cobalt. 



We have given the above examination, more to state
