The London clay, for the first thirty feet, was of a loose texture, 

 reddish brown colour, and contained a good deal of iron pyrites 

 and selenite : for the next hundred and seventy feet it varied in 

 colour from blue to dark brown, and contained many septaria; and 

 the lower part was very sandy. At the depth of 260 feet a i'ew 

 fruits and seeds were procured, — the former resembling those 

 found at Sheppey, and the latter those found at Highgate ; but 

 between 265 and 285 feet the clay abounded with vegetable re- 

 mains. A classed list is given of the fossils obtained by the author; 

 and among those not previously noticed, he mentions the remains of 

 Asterias, a Pentacrinite, six species of bivalves, and two small, 

 straight, tubular bodies, one round, the other square, having an in- 

 ternal radiated structure like that of a Belemnite, but without a 

 central cavity. 



The rock between the London and plastic clays was full of green 

 particles, and contained numerous rounded flint-pebbles. The 

 fossils obtained from it were chalky and friable, and among them 

 the author found Mya intermedia and Natica glaucinoides, shells 

 characteristic of the Bognor rock. 



The plastic clay presented its usual mottled appearance, but no 

 organic remains were noticed in it. 



At the depth of 330 feet a bed of sand, containing small flint- 

 pebbles, occurred, and the water gradually rose from it to within 

 200 feet of the surface. 



A letter was afterwards read from Sir Philip Grey Egerton, Bart. 

 F.G.S.to the Rev. Prof. Buckland, D.D., F.G.S., "On the Ossiferous 

 Caves of the Hartz and Franconia." 



This letter contains a detailed enumeration of the remains found 

 by Sir Philip Egerton and Viscount Cole in the caves of Gailen- 

 ruth, Kiihloch, Scharzfeld, and Baumanns Hohle. In communi- 

 cating these results, the author states that he has made the list as 

 complete as possible, as from the extreme strictness with which the 

 Miiggendorf caves are now guarded, it is not probable that any 

 large collection of bones will again find its way to this country. 

 With respect to the caves of Kiihloch and Rabenstein, he states, that 

 the account which he gave in 1829 of their destruction *, has been 

 fully verified by Lord Cole, who visited them last year j but in con- 

 sequence of the absence of the Baron of Rabenstein at the time 

 of their destruction, the author acquits him of having been impli- 

 cated in the transaction -, and adds, that this nobleman has proved 

 himself a strenuous friend and patron of science, by the care with 

 which he protects the newly-discovered cave of Rabenstein from 

 depredation. 



The author states that he found recent bones of pigs, birds, dogs, 

 foxes, and ruminantia, in every cave which he examined ; frag- 

 ments of rude pottery in those of Scharzfeld, Baumanns Hohle, 

 Gailenruth, and Zahnloch ; and old coins and iron household 

 implements of most ancient and uncouth forms in that of Raben- 

 stein. In the Gailenruth cave he did not find one bone gnawed by
