28. Valuable cabinet of minerals for sale. — The collection of 

 foreign minerals of Baron L. Lederer, the Austrian consul gen- 

 eral, will be sold at public auction on the first days of May, 

 1836,* if not previously disposed of at private sale. This collec-

 foreign minerals, nearly all crystallized or polished, and a great many 

 of them are very valuable and rare. It probably contains a greater 

 number of handsome and rare specimens than any other collection 

 of the same kind in this country. It is arranged according to 

 Cleaveland, in four glass cases at Holbrook & Arnolds', where it 

 may be examined. Each specimen has a black and red number 

 referring to a catalogue, that gives the names under which they were 

 received, those of Werner and Cleaveland, with annotations. Any 

 person wishing to acquire by private sale, is requested to apply to 

 Mrs, Lederer, No. 21, St. Mark's place, New York.

 Vienna with the choicest American specimens, has enjoyed the best
