382 Miscellanies. 



5. Corals and Entomostraca in Chalk. — Mr. Lonsdale has dis- 

 covered that the common white chalk, especially the upper portion 

 of it taken from different parts of England, (Portsmouth and Brigh- 

 ton among others,) is full of minute corals, foraminifera and valves 

 of a small entomostracous animal resembling the Cytherina of La- 

 marck. From a pound of chalk he has procured in some cases at 

 least, a thousand of these fossil bodies. They appeared to the eye 

 like white grains of chalk, but when examined by the lens are seen 

 to be fossils in a beautiful state of preservation. — Address before the 

 Geol. Soc. of London by C. Lyell. 1836. 



MISCELLANEOUS INTELLIGENCE. 



1. Sopra i Vulcani estinti del vol di Noto, del Professore Carlo 

 Gemellaro ; memoria secunda. 35 pp. 4to. Catania, 1835. — The 

 former memoir In the Val di Noto by this active geologist of Sicily, 

 established two eras of calcareous formation, and two of volcanic 

 action. That now before us contains an elaborate account of each 

 variety of rock which this tertiary and volcanic region affords. 



2. Vibration of Railways, by Capt. Denham, jR. N. — Capt. 

 Denham ascertained that the vibrating effects of a passing, laden 

 rail road train in the open air extended laterally on the same level 

 1,110 feet, (the substratum of the positions being the same,) whilst 

 the vibration was quite exhausted at 100 feet when tested vertically 

 from a tunnel. The tunnel was through a stratum of sandstone 

 rock : the rails being laid on a substratum of 12 feet of marsh over 

 the sandstone rock. The method of testing was by mercury reflecting 

 objects to a sextant. The experiments were made in the neighbor- 

 hood of Liverpool. 



3. The Geological Society of London, has awarded the WoUas- 

 ton Medal to M. Agassiz, of Neuchatel, for his work on Fossil Ich- 

 thyology ; and also the sum of 25Z. from the donation fund to M. 

 Deshayes in promotion of his labors in fossil conchology. 



4. New Scientific Journal. — On April 1st, 1836, will appear the 

 London Geological Journal, No. I, with colored engravings, by J. 

 de Carl Sowerby, F. L. S. of new Fossil Echinidae from the Eng- 

 lish strata. — Lond. and Ed. Phil. Mag. and Jour, of Sc. No. 43.
