Having figured Blende or Sulphuret of Zinc, tab. 74 and 

 75, we are glad to add perfect crystals of the Oxide of Zinc. 

 It was sent by Earl Ferrers, from his mines in Leicester- 

 shire, to Miss Codrington, and enriched that Lady's collec- 

 tion of minerals, who discovered these beautiful crystals. 

 It is the only specimen that has yet been noticed ; and we 

 cannot help mentioning that lady's generosity in allowing 

 us to examine it with every freedom. I thought it of much 

 use to figure and describe it as well as was practicable from 

 the little that can be spared from the specimen, which alto- 

 gether does not contain more than a grain or two at the 

 most. It consists of beautiful topaze-coloured crystals 

 dispersed about the specimen, some of which are too small
