284 Reports and Proceedings—Geological Society of London. 
Sheet 17 (next sheet to east of Sheet 16) includes part of Kirkeud- 
brightshire, Dumfriesshire, Roxburghshire (the eastern half of the 
town of Dumfries). More than half of the area of the map is blank 
as representing part of England. ‘This is a pity. The good example 
set in Sir A. Geikie’s Map of England and Wales and in the maps of 
Stieler’s Hand Atlas of giving full detail of all the country within 
the sheet should have been followed. The rocks represented are 
Lower Silurian (Arenig, Llandeilo-Caradoc); Upper Silurian (Llan- 
dovery-Tarannon, Wenlock-Ludlow); Old Red Sandstone (Lower, 
Upper); Carboniferous (Calciferous Sandstone, Moor Rock, Coal- 
measures); Trias; Recent (Marine and Fresh-water Alluvium, 
Peat); Volcanic Rocks (Intrusive Massive), Granite (Felsite, Porphy- 
rite, Andesite), Basalt and Dolerite in dykes and in sheets (Intrusive 
Fragmental), Agglomerate in necks (Extrusive), Andesitic Lavas, 
Basaltic Lavas, Tuffs. 
Compared with Sir A. Geikie’s, 10 miles to 1 inch, Geological Map 
of Scotland, the amount of detail shown on these sheets with 63 times 
the space is not as great as might have been expected.

- The following communications were read :— 
1. ‘‘The Toadstones of Derbyshire, their Field Relations and 
Petrography.” By Henry Howe Arnold-Bemrose, J.P., M.A., F.G.S. 
The district over which the Toadstones are seen may be divided 
into three main areas of volcanic activity, between which there are no 
exposures of igneous rock. 
I. The North-Western or Miller’s Dale Area. 
IJ. The South-Eastern or Matlock Area. 
Ill. The South-Western or Tissington Area. 
In each of these areas there are lava-flows, bedded tuffs, and volcanic 
vents, and in the Miller’s Dale and Matlock areas several intrusive 
sills. In the Miller’s Dale and Matlock areas the igneous rocks are, 
with the exception of the Hopton vent, entirely in the Mountain 
1 May 15th, 1907. At the Special General Meeting held on this day the proposed
