83 COMPARATIVE ANATOMY. 



valleys, and the chalk and greensand elevations. The forma- 

 tion of the Warren itself, and East Wear Bay, was then clearly 

 explained as the Members stood at No. 3 Tower (Copt 

 Point) : consisting of gault it had been easily worn by the 

 action of the sea, the slips being occasioned mostly by the 

 land springs, while Copt Point still stood boldly out because 

 of the hard rocks of the lower greensand which crop out in 

 that exact spot, and may be seen still in situ. 



They then descended to the foot of the cliffs and examined 

 them more in detail. Mr. Mackeson showed that the blocks 

 of greensand scattered about were remarkably deficient in 

 fossils as compared with the Hythe beds, showing among 

 other proofs that they had been formed in a tumultuous sea, 

 not very pregnant with life. Some false bedding, and the 

 fact of some largish pebbles being found mixed up in the 

 stones, were also adduced in support of this view. 



A cordial vote of thanks was given to Mr. INIackeson, and 

 the Members then went fossil hunting. Some good speci- 

 mens of fossil wood bored by worms were found in the Junc- 

 tion bed, also large pieces of selenite. 



June 23rd. Evening meeting by invitation at the Rev. C. 

 L. Acland's. Thirty Members present. On the table were : — 



A collection of skulls of British Mammalia. 



Vertebra of a Whale, found in East Wear Bay. 



Several gigantic specimens of Anodonia cygncea from the 

 Military Canal. 



Living specimens of Hyoscyamus niger (Henbane) from 

 the Warren.

With several books and microscopes. 

 The Rev. E. Langdon, M.A., F.G.S., then read the follow- 

 ing paper on the skulls above mentioned : — 



]\Ir. President, Ladies, and Gentlemen, 



I see I am announced in the notice paper, 

 as about to read a paper on "Comparative Anatomy;" and I 

 would, therefore, wish to say in the first place that I am not 

 prepared to read a paper on so vast a subject as Comparative 

 Anatomy, but rather to talk to you about these skulls that lie 

 on the table before you.
