in the November and December Numbers of the Philosophical 

 Magazine for 1861. Other notices by the same author were 

 communicated and commented upon by Mr. R. P. Greg at the 

 Manchester Meeting of the British Association. Meantime the 

 Imperial Museum had received specimens of the Tula iron from 

 Dr. Auerbach, and a rich collection of East-Indian meteorites 

 through Dr. Thomas Oldham's kind intervention; and Messrs. 

 Laurence Smith, B. V. Marsh, H. A. Newton, Baron Beichen- 

 bach, and others had published their theoretical views on me- 

 teorites. Dr. Buchner had lectured on the same subject at the 

 thirty-sixth Meeting of German Naturalists at Spire, 1861. 

 Another paper by von Haidinger had been communicated to the 

 Academy of Paris by M. Elie de Beaumont*. The collections 

 of meteorites have been greatly augmented since then. The Mu- 

 seum of Munich numbers (March 1, 1868) twenty-two localities 

 of iron or of lithoid meteorites; the University Museum of Got- 

 tingen (July 1,1868) 176 localities, 99 of lithoid meteorites, 77 

 of meteoric iron; the Museum of the Geological Survey of India 

 in Calcutta (December 1867) 254 localities, 159 of lithoid me- 

 teorites, 95 of meteoric iron.

Y IGNITE. — In the eastern part of the province there are 

 found in the carboniferous districts, but apart from the 

 beds of coal, sulphides of metals associated with coaly matter 

 having the characters of lignite. The sulphides are relatively 

 large in quantity, and frequently consist of iron and copper py- 

 rites, with a very rich sulphide of copper, apparently vitreous, 

 though called grey. The enclosing rock of such specimens of 

 these copper ores as I have seen is sandstone, and it is generally 

 more or less impregnated with green carbonate. In one instance 

 galena occurs with iron pyrites in a conglomerate of limestone 

 and siliceous pebbles. The masses composed of the carbonaceous 

 and metallic minerals generally exhibit the form of branches and 

 trunks of trees; and Dr. Dawson points outf that those con- 

 taining copper result from the action of vegetable matter on 

 waters containing sulphate of the metal. The formation of
