MISCELLANEOUS NOTICES. 



The following geological and archaeological articles appeared in the 

 ' Dublin Quarterly Journal ' for May last year : — " On the Elint Imple- 

 ments found in the Gravel of St. Acheul, and their mode of Occurrence," 

 by J. Beete Jukes, F.E.S. ; " [Report of Council of Dublin Geological So- 

 ciety for 1862-3 ;" " On the Chemical and Mineralogical Eelations of 

 Metamorphic Rocks," by T. Sterry-Hunt, F.E.S., of the Canadian Survey ; 

 " Description of an Oak Pile found in the Lake of Geneva," by Mr. 

 Starkey. 



The ' Annales de Chimie et de Physique ' for August last, contains a 

 note by M. Eegnault " On an Apparatus for the Fractional Distillation for 

 estimating the Venale Value of the Essential Oils which are produced by 

 the Calcination of Coals and Schists." 



The ' American Journal of Science ' for November, 1863, contains the 

 following articles : — " On certain Parallel Eelations between the classes of 

 Vertebrates, and the bearings of these Eelations on the question of the 

 Distinctive Features of the Eeptilian Birds," and " On the Classification of 

 Animals based on the Principle of Cephalization," by Professor J. D. Dana ; 

 " On the Eocks of the Quebec Group at Point Levis," by Sir William E. 

 Logan ; " Remarks on the Causes producing the Different Characters of 

 Vegetation known as Prairies, Flats, and Barrens in Southern Illinois, 

 with special reference to Observations made in Perry and Jackson Coun- 

 ties," by Herr Engelmann, of the State Geological Survey ; " On the 

 Earth's Climate in Palasozoic Times," by T. Sterry-Hunt, F.E.S., Chemist 

 to the Canadian Survey. Amongst the notices are : — " On the Phosphatic 

 or Guano Eock of the Island of Sombrero," recently described as a new 

 species of mineral by Dr. Phipson, under the name of Sombrerite. This 

 notice is by M. Julien, a resident chemist at Sombrero, who gives a great 

 deal of information about its extent and physical characters, disputes the 

 accuracy of Dr. Phipson's statements, and asserts that the Sombrero guano 

 is as variable in its composition as any other phosphatic guano, and as little 

 entitled to rank as a new species. "Dr. Phipson," he adds, " cannot pos- 

 sibly have examined with any care a single cargo, I venture to say not 

 even a single ton ; for there is no natural standard by which a represen- 

 tative specimen could be ' well chosen' or chosen at all." " On the Nature 

 of Jade, and on a new Mineral Species described by M. Damour," by 

 Mr. T. Sterry-Hunt. Geological Survey of Canada : Eeport for 1863.
