the rivets are still in position. The blade has a well- 

 marked mid-rib and is ornamented on both faces by twelve 

 finely engraved lines in two series of six, r'unniing the entire 

 length of the blade on each side of the mid-rib. 



Mr. Jackson also reported the discovery of quartz-pebble 

 beds in the Carboniferous Limestone of Caldon Low, Staffs. 

 These pebble beds form the dip slope of the Low on its 

 N.N.W. side, overlooking Cauldon village. At the latter 

 place, a large series of fossils, reminiscent of the " Brachio- 

 pod Beds," of Castleton, etc., has been obtained by Mr. 

 W. sE. Alkins. The beds here apparently follow the pebble- 

 beds in true sequence. Specimens of the quartz-pebble 

 beds from Caldon Low anid of the pebble-bed present in 

 the Castleton district W;ere exhibited, and the relation of 

 the latter tO' the local "Brachiopod Beds " was pointed out. 

 The two pebble-beds differ greatly in composition, that of 

 Caldon Low being made up almost entirely of rounded 

 pebbles of veinstone-quartz with fragments of chert, while 

 that of Castleton consists of carboniferous limestone pebbles. 

 Quartz-pebbles are said to occur occasionally in the latter. 



Dr. H. G. A. HiCKLiNG, F.G.S., drew attention to 

 some of the more recent geodetic work in relation to the 

 figure of the earth, more especially as bearing on the 

 problem of isostasy. Some of the chief criticisms were 

 cousidered in the light of the geological evidence as to 

 movements of the earth's crust. i
