 Messrs. Wood and Komes' paper, Quarterly Joiiinal Geological 

 Society, May, 185S.

a Chalk, h Sand with ehalk-rubble (bed h of coast-section, fig. 1.) 

 c The Purple Clay, called in the borings ' ' bro-\vn stony clay with sand 

 threads." d The Hessle Sand, e The Hessle Clay. / Peat-bed with 

 the stools of trees rooted into it and into e, and with the stems lying 

 flat in the peat, g Silt abounding -^^th Tellina solidula, Scrobicularia 

 jjiperata, Cardium edule, &c. A Salt Water. The length of the section is 

 aboiit one mile — ^the vertical scale being about eleven times the horizontal. 



The numbers along the toiJ denote the Boriags as nimibered in the 

 Dock Engineers' record, being such of the Borings as (with the exception 

 of 1 and 5) run in a continuous line, about 80 yards from the shore. 

 Numbers 1 and 5 being out of that line and nearer the shore, the depth of 

 the water (A) is in their case disregarded. 



The vertical numbers denote the depth below the datum line, which 

 is that of high water. The broken lines indicate the presumed continuation 

 of the beds where the Borings do not descend to them. The portion of the 

 section above the horizontal liae between the 30 and 40 feet mark is that 

 which was fully exposed during the subsequent excavations; but the 

 excavations were in some parts carried deeper, and into the purple clay (c).
