Villot, — . Etudo sur divers gisements de combustibles dans la 

 Province de Teruel (Espagne). [Yarious deposits of Eossil Euel in 

 the Province of Teruel, Spain.] Bull, Soe* Sci. Inclust. Marseille, 

 t. ii. pp. 19-34, 65-88 ; 3 folding plates of fac-simile sketch 

 maps and sections. 

 Chap. I. geological, from a strictly mining point of view ; Chap. II. 

 commercial and industrial. Tho deposits described are 4 to 28 kilo- 

 metres from Montalban. Different opinions have been held as to their 

 geological position ; the author divides them into 4 groups : — 1, lowest, 

 light subcrjstalline limestones (Middle Lias to Urgonian) ; 2, first 

 lignite horizon with yellow siliceous limestones, Trigonia-heds, &c. 

 (Aptian) ; 3, a marked mass of blue and brown clays capped by varie- 

 gated sands with iron- concretions (Cenomanian and Turonian) ; 4, a 

 series of limestones similar to those of 1, but much higher in the series 

 (Carantonian and Ehotomagian). Geographically the deposits are 

 classed as follows : — Basins of Gargallo, Arino, and Utrilias, the last 

 comprising the most important lignitic deposits. Some of the lignites 

 described are of a quality equal to those of Euveau, whilst the others are 

 inferior, but good enough to be worked under favourable circumstances. 

 None are coking or gas coals ; but they might be used for nearly every 

 other industrial purpose, especially the harder qualities. Analyses and 

 statistics are given. G. A. L.

At this spot the Paniselian rests upon Upper Ypresian sands, and 



the Bruxellian beds are entirely wanting. 40 species are enumerated 



as having been found in the Paniselian, of which 20 are also found at 



Mont Panisel (Mens), whilst 17 only are Bruxellian. Indeed some of 



the most characteristic Bruxellian fossils are absent in the Anderlecht 



Paniselian, in which only 3 Ypresian species are found. The writer 



concludes that the Paniselian is a passage-bed between the Lower and 



Upper Eocene. G. A. L.

More than 20 mountains have been in eruption during the historic 

 period. Some of the chief of these are described. All the lavas of 

 Hecla are basaltic. Myrdals Jokull now produces only heated water 

 and sand, but at one time it ejected lava. The greater volcanic activity 

 of Iceland seems to have retreated northwards, to the Yatna Jokull (of 

 which the great Skapter Jokull is but a small part). This is a vast 

 frozen tract, the peaks of the Volcanoes protruding through the snow ; 

 this district has not yet been explored. (See also a letter, " The Yol-
