Analysis of Coprolites and other Organic Remains imbedded in 
the Limestone of Burdiehouse near Edinburgh. By Anruur 
ConneE 1, Esq. F.R.S. E. 
(Read 17th February 1834, and 19th January 1835.) 
Ir is not my intention to enter into any detailed description 
of the external characters of the several interesting organic re- 
mains which are found imbedded in the limestone of Burdie- 
house, that being a task which belongs to their distinguished dis- 
coverer Dr Hizpert. 
As little do I mean to describe the geological relations of the 
limestone bed, that being equally the province of Dr Hisszerz. 
It will be sufficient to state generally, that it forms one of the 
lowest members of the carboniferous group, being inferior in posi- 
tion even to the Encrinal mountain limestone of its immediate vi- 
cinity ; and that besides its numerous animal remains, some of 
which will be mentioned in the sequel, it contains throughout its 
entire mass numerous impressions of land and fresh-water tropical 
plants. 
The chemical constitution of certain of the animal remains is 
the subject which I have humbly undertaken to investigate. I 
shall first advert to the coprolites which are found in vast num- 
bers imbedded in the limestone. 
All the specimens of coprolites examined, appear to agree in 
the following general chemical characters. 
When heated in a glass tube in the state of powder, they give 
moisture and bituminous oil; and test paper held in the tube
