tlio representative bods of Torobratula fimbria zone of tn,e 

 Cottoswolds, and of the more compact Oolitic stone of the 

 neighbouring Ham-hill, so well known in this county, as largely 

 used for ecclesiastical and domestic architecture. Under this 

 theory the Cephalopoda beds of Dorsetshire, instead of lying 

 at the base as in Gloucestershire, will occupy a sub-section from 

 the Trigonia-grit to the Ammonites Humphriosianus zone of Dr. 

 Wright. An examination of the Bradford Abbas district will 

 be made this year at one of our Meld Meetings, whose richness 

 in paleontological remains may be inferred from Professor Buck- 

 man's private collection, where the Ammonites alone may be 

 counted by the scores. I consider a careful comparison of a 

 series of apparently dissimilar forms will demand a fusion of 

 several species into one, their differences arising from the. altered 

 conditions of the Oolitic seas under which the diverging forms, 

 when living, passed their existence. But to return to Powerstock, 

 after an examination of the quarry, under the guidance of Profes- 

 sor Buckman, which presented the characteristic Inferior Oolite 

 fossils Ammonites Parkinsonu, Terebratula gphceroidalis, Terebratula 

 Phillipsii, and Holectypus hemisphcericus, the party pocketed their 

 hammers and prepared for the ascent of Eggardon Hill, whose 

 fortified heights and commanding position were reached with 

 snthusiastic admiration. The day was fine and the atmosphere 

 clear, affording to the spectator a view unsurpassed in beauty. 

 The Atlantic stretched out in wide expanse, a fertile valley 

 intervening between the base of the hill and the shore, inter- 

 spersed with isolated knolls, the Isle of Portland rising above 

 the horizon like a stranded whale, the silvery streak of Chesil 

 Bank in bold relief between the dark soil of the land and the 

 azure blue of the ocean, the deeply indented coast far into 

 Devonshire, adding beauty to the enchanting view. To the 

 north was stretched the range upon which the fortifications of 

 Lambert Castle, Pillesdon and Lewesdon stand. The centre of 

 this panorama, Eggardon forms the south-western boundary of 

 the extensive Chalk-district of the county, whose sinuous Green- 

 gand fringe flanks the Oolitic vallies of the county. Near its 

 summit a bed of highly fossiliferous Chalk-marl was reached, 

 which was attacked by the geologists of the party who collected 

 several good fossils characteristic of the formation, Scaphites, 

 Ammonites, &c. The botanists gathered Genista tinctoria, Poly gala 

 depressa, and Halenaria viridis, together with the more common 

 plants. 



The camp terminates a little north of the spur where the 

 range bends eastward. There are visible proofs of its having 

 been occupied, as well as its environs, by man previous to ita 

 conversion into a fortification or place of refuge. Fosses, mounds, 

 and pit-circles, occur both within and without. Mr. Barnes 

 brought to our notice one remarkable pit-circle, which had two
