number of the more interesting records are described and figured, 

 some of them being new to Britain, or not previously found on the 

 horizons in question. 



As regards the horizons present in Kent, the plant-remains 

 indicate that, in the area so far proved, only Middle or Transition 

 Coal Measures, or both, occur.

The following communication was read : — 



' Supplementary Xote on the Discovery of a Palaeolithic Human 

 Skull and Mandible at Piltdown (Sussex).' Bv Charles Dawson, 

 F.S.A., F.G.S., and Arthur Smith Woodward, LL.D., F.R.S., 

 Sec.G.S. With an Appendix bv Prof. Grafton ElUot Smith, M.A., 

 M.D., V.P.E,S. 



The gravel at Piltdown (Sussex) below the surface-soil is di\dded 

 into three distinct beds : — 



The first, or uppermost, contains subangular flints and 'eoliths,' 

 and one palseolith was discovered there in situ. 



The second is a very dark bed, composed of ironstone and sub- 

 angular flints. All the fossils so far found in the pit have been 

 discovered in, or ti-aced to, this bed, with the exception of the 

 remains of deer. A cast of a Chalk fossil, Echinocorys vulgaris, 

 from the Zone of Micraster cor-testudinariu??i, occun-ed as a 

 pebble. 



The third bed was recognized only this year, and consists of 

 reconstructed material from the underlying Wealden rock (Hastings 

 Series). It is only about 8 inches thick, and contains very big 

 flints (8 to 15 inches long) which have been httle rolled, and are 

 not striated. They are saturated with iron, and have undergone 

 considerable chemical change. They differ very markedly in 

 appearance from the smaller flints in the ujjper strata. No miple- 

 ments, ' eoliths,' or fossil bones have been met with in this bed. 



The floor of the gravel, where tlie remains of Eoanthrojyus were 

 discovered, has been carefully exposed, and many irregularities and 

 depressions have been found to exist. In some of these depressions 

 small patches of the dark overlying bed remained, and new speci- 

 mens were discovered. The method adopted in excavation is 

 described. 



The finds made this year are few but important, and include the 

 nasal bones, and a canine tooth of Eoanthroj)us discovered by 

 Father P. Teilhard de Chardin ; also a fragment of a molar of 

 Slegodon and another of Rhinoceros; an incisor and broken 

 ramus of Beaver (Castor Jiher) ; a worked flint from the dark 

 bed ; and a palaeolithic implement from the dt-bris in the pit. It 

 will be noted that the remains are those of a land fauna only. The 

 further occun-ence of bedded flint-bearing gi-avels in the vicinity of 

 the pit is noted. 



The Authors' foraier conclusions, as to the Pliocene fonns having 

 been derived, are maintained.
