in any of the quarries opened up towards the east. Still it 

 must be admitted that the few Graptolites found were con- 

 fined to a part of the quarry where the beds were less decayed 

 and least weathered. On returning recently from collecting 

 Bj^rozoon, I noticed a shot had been fired after I passed in the 

 morning. On investigating the result, I perceived a thin 

 layer which rests on the building beds, wdiicli often holds a 

 Fucoid. On turning it over I was surprised to find, not what 

 was expected, but a fine Graptolite, the only one I ever 

 fottnd in the bed in question. Mr. Nichol has since 

 discovered a different species in a decayed upper Chert bed. 

 M}'' old friend and fellow worker also placed in my hands a 

 coral which was obtained from the base of " the blue building 

 series, known here as ^' the sand beds''' erroneously. It may 

 be identical with the specimen now in Mr. Scriven's hands, 

 from the glaciated Chert beds. Its flattened appearance is 

 owing to pressure. An un worked quarry of these Niagaras 

 has been reopened in the old Hancock quarry recentlj^, and 

 has already yielded a fine Graptolite.
