Cabinet of Minerals for Sale 



The undersigned offer at private sale the extensive M ineralogical 

 Cabinet of Dr. H. H. Hayden, late of Baltimore City, deceased. 

 Dr. Hayden's devotion to the science of Geology, and his corre- 

 spondence with the scientific men of this country and of Europe 

 for more than thirty years, enabled him to render this collection 

 'most rare and valuable. It has recently passed under the rigid in- 

 spection of Dr. Ducatel, the State Geologist, to whom persons de- 

 sirous of knowing the character of the collection are referred. Ref- 

 erence is made for the same purpose to Prof. Silliman of Yale Col-
