Mr. C. Dawson, in exhibiting specimens of zinc -blende from 

 "the upper beds of the Purbeck formation at Netherfield (Sussex ), 

 remarked that these specimens were obtained from an horizon 

 which was stratigraphically not far beneath the horizon in the 

 Fairlight Clays whence were derived the specimens of zinc- 

 blende previously exhibited by him on June 25th, 1913. l Like 

 the other, the Purbeck zinc -blende probably owed its origin to 

 segregation from Primary and metamorphic rocks, of which both 

 strata are partly composed. He claimed that this discovery indi- 

 cates another link between the Hastings Beds and the Purbeck 

 Series.
