Geological Account of a Series of Animal and Vegetable 
Remains and of Rocks , collected by J. Crawfurd , Esq 
on a Voyage up the Irawadi to Ava , in 1826 and 1827. 
By the Rev. William Buckland, D.D. F.G.S. F.R.S. 
F.L S. Professor of Mineralogy and Geology in the 
University of Oxford. (From the Transactions of the 
Geological Society.) 
For the specimens and notes which form the subject of 
the present communication, the Society is indebted to the 
zeal and activity of J. Crawfurd, Esq. one of its Fellows, 
who having occasion to traverse the Burmese Country, on 
an embassy to Ava, in the years 1826 and 1827, discovered

It is on an examination of these specimens, and of the notes 
contained in Mr. Crawfurd’s daily journal, that the obser-
