It shows the left side of the jaw, measuring 18 inches in 

 length and 4J inches in depth anteriorly. One tooth, exposed in 

 its whole length by the breaking away of the bone, measures 6 • 4 

 inches, of which the crown forms only 2' 6 inches. An animal 

 with almost identical teeth, the Teratosaurus Suevieus, of Von 

 Meyer, occurs in the Lower Keuper of Stuttgardt, thus giving to 

 this type of Dinosaurian a range from the Trias to the Wealden. 



Among the Geological papers, the most important is that by the 

 Kev. J. M. Joass " On the Sutherland Gold-fields," and by Mr. J. 

 J. Murphy " On the Nature and Cause of Glacial Climate." 



We regret that want of space precludes our noticing the nume- 

 rous other papers contained in this number. 



8. METEOEOLOGY. 



Mdeorology in France. — Our last Chronicle was barely in type, 

 when the statements contained in it relating to the organization of 

 meteorological operations in France were shown to be incorrect. 

 We learn now that the Government has communicated to the So- 

 ci6te Meteorologique its intention of instituting a complete system of 

 meteorological observations, in a connection more or less intimate 

 with the Society. A commission has been appointed, with Prof. 

 Charles Sainte-Claire Deville as its President, to superintend the 

 work. A central observatory has been established at Montsouris, 

 near Paris, with which it is hoped that other institutions will soon 

 be affiliated, and the issue of a daily bulletin of the observations 

 made at Montsouris has been set on foot since the beginning of July. 

 It may therefore be expected that ere long a complete system of 

 meteorological observations will be in operation, and we cannot but 

 express our satisfaction at the evidence which these facts afford that 

 the authorities in Paris fully recognize and identify themselves with 

 the work so long and so well done by the Meteorological Society 

 of France. As regards the issue of the Bulletin International, no 

 modification of the service at the Observatoire Imperial wiU be made 

 in consequence of the change. 



The Aurora. — The remarkable auroras noticed on April 15 and on 

 May 13, of which Mr. Barber was so kind as to furnish a notice for 

 our last number, have attracted very considerable attention over the 

 whole of Europe, and have formed the theme of several interesting 

 communications to scientific societies. Among the most important 

 of these have been the notices submitted by MM. Silberman and 

 C. Sainte-Claire Deville to the French Academy, and contained in the 

 Comptes Eendus. These gentlemen, the former especially, have
