period ; coral-reefs in the Pacific ; the origin and age of the 

 EngHsh Channel — is not to be taken in hand lightly ; the pajier is 

 a failure, for the reason stated in the other case, the subject 

 has mastered the author. 



(4.) Mr. Gr. M. Browne records an earthquake-wave which ap- 

 peared at Admiralty Bay, Island of Bequia, on 17lh March, and 

 advanced 3 feet in height, a distance from 70 to 350 feet beyond 

 high-water mark. A second smaller wave followed. 



(5.) Captain F. W. Hutton sends a note on an extinct Volcano 

 (Nga Tutura) in New Zealand, previously described'by Mr. Heaphy.* 

 Captain Hutton thinks the fluid matter that escaped as lava was 

 not connected with any deep-seated matter in the interior, but may 

 have come from rocks 1000 feet below the surface. We are glad 

 to see Mr. David Forbes was present to condemn the rashness of 

 such a statement made at hazard ; — the idea of fluid rocks only 

 1000 feet below the surface is dreadful. 



(6.) Mr, Wood Mason calls attention to the discovery of teeth 

 of Dahosaurus in the Kimmeridge Clay of Shotover Hill. Dako- 

 saurus had, however, previously' been found at Potton, near Cam- 

 bridge, and described by Mr. John F. Walker, B.A., F.G.S., hi the 

 * Annals and Mag. Nat. Hist.,' 1SG6. 



(7.) Dr. Duncan's paper on the Test of Amphidefus was 

 withdrawn. 



(8.) Mr. Bauerman's '* Geological Reconnaissance in Arabia 

 Petraea " is, we trust, the first only of a series of good papers on this 

 interesting country. Hills of gravel-topped alluvium, gravel-plains, 

 gently swelling or terraced plains of sand, a kind of oolite made up 

 apparently of rolled fragments of shells, dipping sea- wards ; blue 

 shaly clays with gypsum ; granular massive gypsum, or alabaster ; 

 clifis of calcareous grit-stone finely stratified ; white chalky lime- 

 stone ; a bluish grey or white crystalline (Tertiary) limestone, and 

 a soft limestone (these last bearing Nummuhtes), a series (600 feet 

 thick) of Lower Cretaceous rocks, and of dark-red soft sandstone, 

 with marly partings (hke the Lower New Bed Sandstone about 

 Chester), these are the principal formations met with. 



Old mines were observed in several places in a bed of iron and 

 manganese, and remains of copper-works of considerable extent. 

 Turquoise-mining has been carried on by the late Major Macdonald, 

 and subsequently by a Frenchman with more or less success. The 

 implements of still earlier miners, discovered by Mr. Bauerman, 

 are recorded in the Chronicle of Prehistoric Archaeology. 



(9.) Dr. Le Neve Foster and Mr. Bauerman have a joint note on 

 the occurrence of Celestiue in the Nummuhtic Limestone of Egypt. 



The Celestine occurs not only in detached crystals, but also,
