cupro-descloizite is confirmed by Frenzel himself, who is quoted as 

 writing to Professor DesCloizeaux that he had not thought it 

 necessary to consider as an essential constituent the two per cent 

 of water which he had found in tritochorite.

Art. XLY. — A new Meteorite from Mexico / by J. Edward 



Whitfield. 



While in Mexico during the summer of 1888, Prof. H. A. 

 Ward, of Ward and Howell, Rochester, N. Y., obtained an un- 

 described mass of metoric iron weighing 33*0 kilos. 



The meteorite was found on a peak of the Sierra de San 

 Francisco, called La Bella Roca, in front of Santiago Papas- 

 quiaro in the state of Durango. The date of its discovery and 

 the name of the finder are unknown. 



The two greatest dimensions of the mass are 24-13 cm X 

 34'92 cm ; an idea of the shape and general appearance may be 

 had from the accompanying cut which shows what is supposed 

 to be the front and back of the meteorite;, at least during the 

 latter part of its flight.
