put as to the occurrence of the gypsum ; but the present 

 section clearly shows five beds, all fully as white and 

 granular as the fine thick deposit met with in the per- 

 mian marls at Barrow Mouth, and described by me at 

 p. 254 of my first paper. 



No notice of the conglomerate-bed is given in the bore ; 

 but it is probable that one was met with, as the pebbles 

 usually characteristic of that deposit were found by me 

 in the materials which had been brought up. 



The thickness of the lower red sandstone, the Collyhurst 

 sand, reaching to 423 feet, shows to what extent that 

 deposit may be met with even on the outcrop of the per- 

 mian strata. The boundary between it and the under- 

 lying coal-measures is difficult to determine, as no fossil 

 organic remains were met with; but it was probably in 

 the 5 inches of red marl, marked with an asterisk, as the 

 coal-measures were then certainly reached, bright coal 

 being found in some of the metals brought up by the 

 boring-instrument . 



In this section, the red marls, with beds of limestone 

 and gypsum, and the Collyhurst soft sandstone, are both 

 well developed ; but no trace of the pebbly beds contain- 

 ing coal-plants, as met with at Astley and Bedford, was 

 found. These last-named strata were also absent in the 

 Chorlton-on-Medlock section, hereinafter described, as 

 well as in the Seedley section, described at p. 103 of my 

 second paper ■^. 



Manchester Section. — Chorlton-on-Medlock. 



In my first paper, before alluded to, as well as in another 

 communication of mine printed in the first volume of the 

 Transactions of the Geological Society of Manchester, 

 this is described at considerable length. It commences 

 near All Saints' Church in Oxford Road, and continues all
