Lias and Inferior Oolite at Braun Jura, at Gmiind, and at 

 Giindershofen, on the Lower Ehine. "The Sands," urged the 

 Doctor, "possess a fauna entirely different from that of the 

 Inferior Oolite, and should be ranged with the Upper Lias, to 

 which they palseontologically belong." 



Mr. Symonds, of Pendock, drew attention to a subject of 

 great interest to the public in general, and one especially fitted 

 for examination by Cotteswold Geologists, viz., the "weathering" 

 qualities of the so-called Bath Stone. It is weU known that 

 under this name are comprised building-stones of very different 

 qualities, much of which, when used for external purposes, are 

 utterly valueless, splitting and shivering with the first winter's 

 frost. Mr. Symonds urged upon the Club the desirability of 

 instituting careful experiments, with a view to testing the 

 qiiahties of different beds of OoHte, and thus signalising those 

 which could be reKed upon as weather-stones. Dr. Wright 

 observed that the whole education of builders ought to be re-cast; 

 it being most painful to see how good money is frequently 

 thrown away in consequence of the use of improper materials. 

 It is still an open question, which are the best qualities of 

 building materials ? The committee appointed to decide on the 

 best to employ on the Houses of Parliament, failed. The 

 building-stone of Bath, which is Great Oolite, has advantages 

 in some respects over the Inferior OoHte. It would seem difficult, 

 however, to lay down any fixed rule on the subject, beds varying 

 in the same quarry. It is asserted, moreover, that the best beds 

 of stone, if used in a green state, will pulverise rapidly; while 

 the same beds, if allowed to season, will bear any amount of 

 exposure. This subject is one which in former years much 

 engaged the attention of one of the oldest members of the 

 Cotteswold Club, Mr. W. H. Hyett, F.E.S., of Painswick, who 

 instituted a series of experiments on the qualities of the Inferior 

 Oolite building-stones, bearing more particularly on the weather 

 stone qualities of the quarries of Bisley and Minchinhampton, as 

 compared with the more perishable material of Painswick and 

 Leckhampton, from whose commiuiication to lue on the subject 

 I quote as follows: —
