234 Reports and Proceedings. 



the whole of the land is here being systematically explored for these 

 valuable nodules, which lie at an average of six or seven feet from 

 the surface. One field after another is taken in hand, the surface 

 soil removed, the Coprolite bed of about twelve inches in thickness 

 is then taken out, the soil is carefully replaced on the surface, and 

 the field is then again ready for tillage. The so-called "Coprolites " 

 are washed by horse power to remove the sand and loam in which 

 they are embedded, and then they are ready for conversion into 

 manure. A considerable number of fossils, chiefly Brachiopods, 

 Terebratula biplicata being most abundant, were obtained. The 

 party returned to Cambridge, and in the evening were most hospit- 

 ably entertained at St. John's College by the Eev. T. G. Bonney, 

 M.A., Fellow and Tutor of the College. — On the following day, 

 Tuesday, the 11th, Up ware, between Cambridge and Ely, was visited. 

 At this place, situated in the fens and near to the river Cam, very in- 

 teresting sections have been exposed in consequence of the search 

 for Coprolites. The G-ault, which here becomes very thin, has been 

 cut through, and Lower Greensand strata reached. In the latter 

 deposit at the top of the Gault, a bed abounding in " Copro- 

 lites" is found, and this bed contains characteristic Lower Green- 

 sand fossils, together with several new species of Brachiopods, 

 described by Mr. J. F. Walker, B.A., P.G.S. Cropping out within 

 a very short distance from this exposure of Gault and Lower 

 Greensand is a remarkable rock full of fossil corals, which has 

 hitherto been called Coral Eag, but which Mr. Harry Seeley, who 

 has devoted great attention to the strata of this district, considers to 

 be of Kimmeridgian age. This rock, to which Mr. Seeley has given 

 the name " Upware Limestone," is underlain by " Ampthill Clay," 

 which would appear to be the equivalent of the Coral Eag of Oxford- 

 shire, Wiltshire, Dorsetshire, etc. The Brachiopods in the Infra- 

 Gault coprolitic bed are abundant, especially Terebratula sella, T. 

 prcelonga, and Waldheimia or Terebratella Davidsoni, many fine 

 specimens of each of which species were obtained. The drive back 

 to Cambridge, twelve miles through the fens, was quickly and agree- 

 ably accomplished, and the party returned to London highly gratified 

 with their visit to Cambridge. During May the Association will visit 

 Oxford, Grays in Essex, and Yeovil in Somersetshire. — J. L. L. 



Geological Society of Glasgow. — L The ordinary monthly 

 meeting of this Society was held in Anderson's University, on Thurs- 

 day evening, 5th January. Mr. Edward A. Wiinsch, Vice-president, 

 in the Chair. 



Mr. James Thomson, F.G.S., read a paper " On the Occurrence of 

 CoelacantJius Upturns at Newarthill, and Palceoniscus Wardii at Fossil." 

 He briefly described the scales, fin-rays and head plates of Coelacan- 

 ihus, which had been found in a detached form in the neighbouring 

 coal-measures, and which the examination of a nearly entire specimen 

 from the Staffordshire coal-field had now enabled him to identify. 

 It occurs in the upper members of the Carboniferous system in Scot- 

 land, in a shale overlying the Ironstone of the Airdrie coal-field.
