show that it varies in thickness in difTerent places from about 10 

 to 20 feet. It bears every mark of a tranquil sedimentary deposit 

 from water; but the lamina? are sometimes divided by thin layers 

 of fine sand, or occasionally, but rarely, by a layer of small flint 

 pebbles. There are no marine remains; but land-shells are said 

 to occur sometimes in this deposit. The bnck-earth rests upon a 

 bed of chalk-flints, .the greater part of which are not water-worn ; 

 and beneath these is chalk, which is loose and rubbly in the 

 upper part. 



This brick-earth is not connected with the alluvial soil of the 

 present valley, but appears to have been deposited when the val- 

 ley was at a higher level ; for it forms a low terrace along the 

 side of the river Wily, between Salisbury and Wilton, rising 30 or 

 40 feet above the present water-meadows. It is necessary at lea&t 

 to suppose that when these beds were accumulated, the water rose 

 much higher than it now does. 



The bones are in a very decomposed state, but have no appear- 

 ance of having been rolled ; they are found in the lower part of 

 the brick-earth, and not in the subjacent flint-gravel. And in 

 one spot there is reason to believe that the remains of an entire 

 skeleton of an Elephant might have been procured. 



This meeting terminated the Session, and the Society adjourned 

 to Friday evening, the 2d of November next. 



ZOOLOGICAL SOCIETY. 



We have the satisfaction to report the further progress of this 

 society towards the attainment of the objects of its institution, in 

 the accession of new members, and new contributors to its col- 

 lections ; the arrangement of the subjects in the Museum in Bruton 

 Street; and the opening, to the members and their friends, of the 

 Menagerie and Gardens in the Regent's Park. Since the general 

 meeting on the 7th of March, at which the Marquis of Lansdowne 

 was unanimously elected President of the Society, in the place of 

 Sir T. S. Raffles, its lamented founder, as noticed in our last
