1. ‘‘ Professor George Sinclair’s ‘Short History of Coal’, published 
in Edinburgh 1672.”” By D. Tait. 
In this paper Mr. Tait brought before the notice of the Society 
a work called The Hydrostaticks, written by George Sinclair, Professor 
of Philosophy and Mathematics in the University of Glasgow, who is 
best known as the author of Satan’s Invisible World Discovered, 
a book on ghosts and witches. A section of Zhe Hydrostaticks is 
entitled ‘‘ A Short History of Coal’’. In it is given the first account 
of the Midlothian coalfield. The outcrop of the ‘ great’ seam of coal 
is traced round the basin and also in the neighbourhood of Prestonpans 
and Tranet in a remarkably accurate manner. He notes that whin 
dykes often render coal-seams with which they come into contact as 
if they had been burnt, and records many other interesting geological 
facts in the neighbourhood. 
2. ‘‘A Diatomaceous Deposit at the East End of Loch Leven, 
Fifeshire.”” By J. Duncan. With Note on the Diatomaces by 
George West. i 
This deposit forms part of the alluvial flat at the east end of Loch 
Leven. It was first observed in a trench cut for a water-pipe track 
near the Old Gullet Bridge, which crosses the former course of the 
River Leven near Lochend farm-house, and afterwards traced 
eastwards to East Bowhouse, a distance of about two miles. The 
greatest thickness of Diatomite met with in the series of pits made
