Second Notice on the Argentiferous Ores of JDeoghur. — By Henry 

 Piddington ; Curator, Museum of Economic Geology. 



In my first notice of these remarkable ores (Journal Vol. XX. p. 1. 

 I stated that several of them contained silver, and were in fact the 

 true Mexican Colorados and Peruvian Pacos, and that working a pound 

 weight of two of them by the Spanish Amalgamation process, I had 

 obtained an average produce of 8£ and 13.5 Marcs of silver : I also 

 stated that some of the ores contained more promising proportions of 

 silver.
