MSrhoire sur les Volcans eteints, 8^c. Memoir on the Extinct 

 Volcanoes of the Val di Noto in Sicily. By G. Gemellaro. Actes 

 de VAcad, des, Sci. Nat. de Catane, Vol. III. 



Doloraieu first directed the attention of geologists to the extinct vol- 

 canoes of Sicily, which, from their neighbourhood to Etna, had not 

 attracted the observation of the ancients. M. Gemellaro places in 

 the Val di Noto the outlet of that subterranean fire, whose products 

 cover the surrounding country. He admits two calcareous deposits, 

 and two great volcanic eruptions. The most ancient of these deposits, 

 which forms the mountains, dates from the first eruption, which took 

 place by nine craters, whose site is yet perceptible. The newest 

 calcareous deposit which constitutes the lower formations of Sicily, 

 covers a part of the preceding ; after this deposit the eruptions took 

 place, which produced the bed of lava, expanded in different direc- 

 tions, and to more or less considerable distances, and which is mixed 

 in many places with alluvium. 



Meeting of the Cultivators of Natural Science and Medicine, 

 at Hamburgh, in September, 1830. By James F. W. Johnston, 

 M.A. &c. &c. — Edinburgh Journal of Science, April, 1831. 



This is a graphic sketch of the proceedings of the meetings of German 

 naturalists, at the last of which Mr Johnston assisted. At a time 

 when a proposition is made for establishing a similar meeting in 

 Great Britain, this paper becomes peculiarly appropriate ; and if the 

 perusal of it do not light up in the reader a desire to be a witness 

 of such a scene in his own country as that here described, whose 

 characteristic object is amiable feeling and good fellowship among 

 a class of men who, to their disgrace be it said, are notorious for 

 jealousy and ill will, we should be hopeless of the success of the 

 project of which we have given notice in another part of this 

 number, (p. 269.) 

 It will be recollected, that an attempt was made last summer to establish 

 a similar meeting in Edinburgh, but without success. The plan 

 of choosing York, a central and delightful city, for the first place of 

 assembly, is, however, a great improvement on the original suggest 

 tion, and we sincerely wish it may be carried out. 



Writings of M. Fuchsel. 



M. Fuchsel was the founder of the public museum of Natural History 



at Rudelstadt, in Germany, where he died, in 1773. 

 In 1762, he published the remarkable essay, entitled Historia terra et 



Maris, ex historia Thuringice per montium descriptionem erecta. Acta 



Acad. Elect. Maguntinae, (Proceedings of the Society of Mayence, 



established at Erfurt,) 11. p. 44-209. 

 This memoir is followed by another entitled Usus Historice suce terra et 



maris. Ibid. 209-244. 

 He gave also a geological map of Thuringia, in which the formations 



are indicated by letters, and which contains many sections. This 



was the first geological map ever published, and for some time the 



only one. 

 In 1773, he published a work in German, entitled, Eittwurf zu der 



celtesten Erd und Menschen geschichte, ( Sketch of the Ancient History 



of the Earth and of Man,) 8vo. pp. 275.
