Iviii PROCEEDINGS, 



fisli-remains — teeth, scales, and pieces of bone. Its green- 

 coated nodules are much less phosphatic than are those of the 

 Cambridge Greensand. A fault in the pit is well shown by this 

 bed being thrown down to the right, and a slanting streak of 

 crushed chalk clearly indicates the line of fault. 



A chalk-pit under Pitstone Hill was next examined. Here 

 the junction of the Lower and Middle Chalk is well shown, with 

 the two BelemniteUa marly bands separated by hard white chalk 

 (3 feet in all), forming the top of the Lower Chalk. In these 

 beds the characteristic fossil Adinocamax plenus was found, and 

 also Ostrea vesicularis. The hard, massive, nodular Melbourne 

 Rock, forming the base of the Middle Chalk, was seen above the 

 marly bands, and in and above it several specimens of the zonal 

 index-fossil, Rhynchonella Cuvieri, were collected. 



A little farther on, on the opposite (right-hand) side of the 

 road, near Folly Farm, there is a pit in the RhyncJionella Cuviei'i 

 zone, with this species common, and Inoceramns mytiloides 

 abundant, though mostly in fragments. Both these species 

 were found on this visit. Mr. Kidner has also collected from 

 this pit Conulus (Echinococciis) sub-rotundatus, Discoidea Dixoni, 

 Inoceramus latus, Terebratula biplicata, Gamer ospongia stib- 

 rotundata, and Ventriculites sp. 



On arriving at Tring Station tea was had at the Royal Hotel. 

 Thanks were accorded to Mr. E. T. Newton, F.R.S., for 

 identifying some of the fossils, and to Mr. Kidner for acting as 

 Director. To his report to the G-eologists' Association the 

 Editor is indebted for most of the information here given. 



Field Meeting, 22nd June, 1907. 

 REDBOURN AND AUBREY CAMP. 



This meeting was held in conjunction with the Barnet Natural 

 History Society, and was under the direction of Mr. C. G. 

 Kiddell, the Secretary of that Society. * 



From the village the party traversed the avenue of fine old 

 elms which extends the whole length of the common and leads 

 to the Church, near which rise some springs which form a pool 

 and a small brook, the Red Burn, about a mile in length, which 

 joins the Ver a short distance below the village. This brook 

 does not always flow ; in fact, its flowing was held in superstitious 

 times to presage some calamity. Now we take it as an indication 

 that the water-level in the Chalk is comparatively high, and that 

 our underground reservoir is not likely to be depleted in the 

 ensuing summer. 



The Church, dedicated to St. Mary, was first visited. It is 

 believed to mark the site of an ancient village, the present 

 Norman building, erected about 1100, standing on a Saxon site. 

 All which remains of Norman construction, however, is the 

 arcade of the north aisle and possibly the small pointed western
