2. Notes on a Section o/Lower Lias and EniETic Beds, near Wells, 

 Somerset. By the Rev. P. B. Brodie, M.A., F.G.S. 



The accidental lowering of a road at Milton Lane, one mile and a 

 half north of Wells, exposed a very interesting section of Lias and 

 Ehaetic beds, which has not been referred to by Mr. Dawkins in his 

 paper '' On the Relations of the Liassic and Rhsetic Series in Somer- 

 setshire." This section is the more deserving of notice because, as 

 a general rnle, the sections in the imm.ediate neighbourhood only 

 exhibit the White Lias and Rhaetic beds, and these have not hitherto 

 been recorded so near the city in a northerly direction, nor so close 

 to the Mendips; and in this case we have the " Lima-beds" the highest 

 seen, passing into and overlying the White Lias and the Avicula-con- 

 torta zone. The nearest section to Wells described by Mr. Dawkins, 

 showing the White Lias and Rha3tic series, though very obscure, is 

 at Pen Knowle, about five miles west of the town. The Milton-Lane 

 section gives a clearer view of the succession of the ^' Lima-beds" 

 downwards, and I can confirm Mr. Dawkins's* statement that the 

 "White Lias" rests immediately upon the Rheetic bedsf ; for whether 

 the strata below No. 4 in the annexed section, down to the " White 

 Lias," belong to the " Lima series," which is most probable, and to 

 ^ which I have referred them, or form a reduced equivalent of the 

 " Insect and Saurian beds," it is evident that the latter do not here or 

 ' elsewhere underlie the " White Lias." The following is the section:|: 

 at Milton Lane, in descending order : — 



^ This was also pointed out by Mr. Bristow in his paper communicated to the 

 Bath Meeting of the British Association. 



t At Harbury, in Warwickshire, the Lima-beds rest immediately on the 

 White Lias.
