Tuesday, June 24th. — Owing probably to the unpromising state of the 
weather and other causes, only a few of the members accompanied the walk 
of the Section to Upton. The members were met at Saltford Station by 
Mr. Parker, Jun., who very kindly acted as guide to the several places which 
would give the best illustration of the middle and upper lias. On alighting 
at the Saltford Station the party at once proceeded to examine the capital 
section of the beds of the lower lias, afforded by the Mangotsfield Railway. 
The fossils here were numerous and a good collection made. Among others 
were the following genera : — Modiola, Axinus, Cardium, Lima, Myacites, &c. 
comprising many species. After spending some time here, the members 
walking through the little villiage of Swinford, reached the narrow lanes 
leading to the edge of Lansdown. Some of these are noticeable for their 
Roman origin, having been originally made for military purposes. After a 
search among the nettle-grown banks of the marlstone and beds of the middle 
lias eeming with fossils, the height of the marlstone was taken in a a lane 
south-west of North -stoke, by Mr. Stoddart's barometer and was determined 
to be one hundred and sixty-one feet above the mean sea level ; about fifty 
feet higher was the base of the upper lias sands. Owing to the surface of the 
ground being so covered up, it could not be ascertained whether these beds 
were in their original position or the effects of a landslip which so often 
occurs on the Lansdown slopes. More observations on other parts of the 
hill must be made before this point can be considered as settled. The fol- 
lowing fossils were noticed : — 
Pecten 
Rhynchonella (2 specimens) 
Terebratula 
So numerous were the fossils that some of the beds were entirely composed of 
of them such as the pecten and ammonite beds. Between Upton and North- 
stoke was a quarry noted for its crustacians, but time did not permit of its 
examination. From thence the members proceeded to Mr. Parker's charming 
Ammonites bifrons 
, , annulatus 
variabilis 
,, moorei, &c.
