December 7, 1885. 



Eegular Business Meeting. 



The President, Dr. J. S. Newberry, in the Chair. 



Forty persons present. 



Prof. Lazarus Fletcher, Curator of the Mineralogical 

 Department of the British Museum, and Prof. Valentine 

 Ball, Director of the Science and Art Museum, Dublin, were 

 elected Corresponding Members. 



In behalf of Mr. G. F. Kunz, Mr. B, B. Chamberlin pre- 

 sented for the notice of the Academy a large almandine garnet, 

 seven inches in diameter, and nine and one-half pounds weight, 

 found during the past week in an excavation on 35th street, between 

 Broadway and Seventh avenue. Mr. Kunz regarded the crystal 

 as the largest of the kind ever reported from the Island. It is in 

 good condition, showing twenty faces of the trapezohedron and 

 nearly half as many faces of the dodecahedron. The combina- 

 tion of the two forms gives it additional interest. The edges of 

 the rhombic faces are truncated. The general color of the garnet 

 is a reddish brown modified by olive-green spots of chlorite. The 

 fractured portion of the crystal shows dodecahedral cleavage. 



He also announced for Mr. Kunz that Herderite had been 

 found at a new locality in Maine, a place known as Morrow Ledge, 

 near the Hatch farm. Auburn, Maine, where fine colored tour- 

 malines were found two years ago. With the Herderite were found 

 large quantities of lepidolite, amblygonite, Cookeite, and some 

 colored tourmalines of little value. Of the crystals exhibited, one 

 measures 15 mm. in length by 8.5 mm. in diameter. This has a 

 light-yellow color, transparent in parts, and with good brilliant 

 faces. Another crystal, quite opaque, measures 20 mm. by 

 16 mm., and has imbedded in it a quartz crystal and a small 

 piece of transparent green tourmaline. 



Mr. Kunz also announced by Mr. Chamberlin the dis- 

 covery of a new locality for prehnite. Fine distinct primitive 

 crystals measuring 5 mm. on a face were found near the city of 

 Auburn, Maine. The mineral was first identified at this locality 

 by Mr. N. H. Perry, and procured later by Mr. S. F. Lamb.
