Preliminary Note on Recent Discoveries of 

 Batrachians and other Air-breathers in 

 the Coal-Formation of Nova Scotia. 



By Sir J. William Dawson. 



This note is intended to record the fact of the discovery, 

 in 1893, of erect trees containing remains of land animals 

 at two horizons in the coal-formation of the South Joggins, 

 in addition to that in which such remains were found by Sir 

 C. Lyell and the writer in 1851, and from which so many 

 additional trees of this character have been extracted in 

 subsequent years. Details as to the species in the recently 

 discovered trees will be published when their contents have 

 been worked out and studied. 



The remarkable section of coal- formation rocks at the 

 South Joggins, in Cumberland County, Nova Scotia, has 

 long been known as one of the most instructive in the 

 world ; exhibiting as it does a thickness of 5,000 feet of 

 strata of the coal-formation in a cliff of considerable height, 

 kept clean by the tides and waves, and in the reefs extend- 

 ing from this to the shore, which at low tide expose the 

 beds very perfectly. It was first described in detail by the
