The Phelan bed is, on the best evidence, identified with the Bridg- 

 port or Lingan bed on the west, and the M'Aulay bed at Cow Bay 

 on the east. Assuming this to be correct, the following table gives 

 the continuation of the section, as shown in a MS. report of Mr Mosely 

 of Halifax, kindly communicated to me by Mr Joseph B. Moore : —

The bed three feet thick about 100 feet below the M'Eury Seam appears to have 

 been discovered after the publication of Lyman's Report; and Mr Poole mentions a 

 bed one foot thick as occurring between the former and the "M'Eury."
