horizontally against their flank, having the same degree of dip 
as at Westbury, viz.: about 2° S.S.E. It is to be observed, that 
this point is not noted upon the Maps of the Geological Survey ; 
it has, therefore, probably hitherto escaped the notice of the staff 
of able and lynx-eyed Surveyors, by whose labours that magni- 
ficeut national work has been so indefatigably and so successfully 
elaborated. 
Wednesday, 17th of August. The Club met at Swindon; the 
attendance was, however, but thin, not more than half-a-dozen 
presenting themselves at the rendezvous at breakfast; of these, 
the majority proceeded on wheels to Abury, while the geological 
Section, represented by the President and Mr. Charles Moore, of 
Bath, the well-known paleontologist, addressed themselves to the 
geology of the district, which they traced from the quarries in the 
Portland Oolite above the Town, to the summit of the opposite 
chalk escarpment at Burdrop Park. 
The dirt-bed in the Swindon quarry, which has yielded a very 
interesting series of fossils to the persevering industry and in- 
telligence of Mr. Moore, was closely investigated ; but it does not 
yield up its treasures to every casual explorer; and one valve of 
a Cypris was the sole, yet satisfactory result of much laborious 
examination. 
In the course of the evening, Mr. Moore exhibited a beautiful 
series of minute organisms from this bed, concerning which he 
offered some interesting observations. 
The band of dark sandy clay, marked No. 4 in the Section 
given in the Memoirs of the Geological Survey, Sheet 34, he con- 
siders to be the equivalent of the dirt-bed of the Swanage Sec- 
tion, and although he stated that he had as yet found no traces 
of Mammalia in it; yet he has obtained teeth of Macelodus 
Brodiei, and of other reptiles found in the Purbeck strata of 
Swanage. But the remains of greatest interest are some minute 
vertebree and articulated bones, which Professor Owen has decided 
to belong to a perennibranchiate Batrachian, an Order not pre- 
viously known below the Tertiary beds. 
Cypris is found in the same bed, and one or two species of 
Chara, with other fruits, and also a numerous series of 'Testacea. 
This was a Ladies’ Meeting, but I regret to say, that the 
Ladies did not respond to the invitation conveyed in the printed 
circulars, to the extent it was hoped they would have done. One 
only gracing the table with her presence. Let us hope this was 
due rather to the inconvenience of a somewhat distant locality, 
than to lack of sympathy with the object of our meeting. The 
occasional presence of the gentler sex at such gatherings of the 
Club, as may be favourable to their coming amongst us, should by 
all means be encouraged, as tending to exert a humanizing in- 
fluence over the rougher nature of even the most intellectual of 
philosophers; while the Ladies on their part, cannot fail of
