3. The specimens of Wavelliteare from the neighborhood of Macungie, 

 Lehigh Co., Pa. They present radiating nodules on limonite ; their color 

 is white. These crystals were considered to be calamine, and on this 

 account we experienced some difficulty in ascertaining the locality. In- 

 deed, we were obliged to show qualitative proof of the absence of zinc to 

 the parties interested, before being made acquainted with the history of the 

 specimens. Our analyses were made of some of the Avell-delined crystals. 

 The method of analysis pursued, was that described by Dr. F. A. Genth, 

 in Am. Journal of Science, etc., II. Vol. 23, p. 423.
