After the lapse 
of three years 
I find that the above 
couple 
has retained its powers almost unimpaired. 
E. W. Binney, F.B.S., V.P., said that many years ago, when 
he first came to Manchester, the red sandstone found under the 
city was known by the nameof theUpper New Bed Sandstone, 
the lowest division of the Trias and the equivalent of the Bun- 
ter. The authorities of the Geological Survey have divided 
it into Lower Soft Bed Sandstone, Pebble Beds, and Upper 
Soft Bed Sandstone ; but the Pebble Beds are the deposits 
chiefly found under Manchester. Superior to this sandstone 
he had seen a deposit of red marls which he thought resem- 
bled the red marls of Cheshire, and at page 37 of the 1st 
vol. of the Transactions of the Manchester Geological Society 
he states that “ this deposit, extending over so great a por- 
tion of the neighbouring county of Chester and reaching to 
a great thickness in the salt beds, is seldom to be seen in 
the south east of Lancashire. The only place where I have 
observed it is on the south of the town along the line of the 
Oxford Boacl from All Saints’ Church to St. Peter’s Square. 
After going through the diluvial clay a thin band of two 
feet in thickness occurs. In Chepstow Street leading out 
of Oxford Boad this bed is between four and five feet in 
thickness. In the middle of it occurs a light coloured layer 
resembling fullers’ earth in appearance, -which briskly effer- 
vesces when treated with dilute hydrochloric acid. The 
lower part of the marl becomes arenaceous and passes
