96 PROCEEDINGS OF SOCIETIES. 



the uses of the blowpipe, and its application generally to the purposes of Mine- 

 ralogy. A short analysis of the scientific arrangement of minerals into classes, 

 &C, was given, and the lecturer concluded with a few remarks preparatory to 

 entering upon the separate description of each mineral, more particularly those 

 indigenous to our own country. 



Mr. Wolseley delivered his third lecture on Mineralogy at this Institu- 

 tion on December 26. Resuming his subject at the point at which he closed 

 the preceding lecture, Mr. W. proceeded to consider the specimens found 

 in the mineral kingdoms, under a classification of nineteen orders, giving 

 descriptions separately of such individuals as are indigenous to the country. 

 He noticed the chief physical characteristics of the whole, and the localities 

 whence they are principally procured, and with what substances generally 

 combined and associated. He next gave a detail of the uses of such as are 

 most commonly available to the comforts and wants of man, and entered 

 into a description of several, particularly of calcareous spar, and the several for- 

 mations of the carbonate of lime. He then proceeded to describe the several 

 orders of Ore Metal, Pyrites, &c, giving a history of the species contained under 

 each order respectively, and more especially of such as are procured in the mines 

 of this country, and the various uses to which the metals are appropriated. He 

 examined also the different orders of Gem, Malactrite, Spar, &c. ; and in con- 

 clusion directed attention to those species which are most frequently met 

 with in Great Britain, and briefly adverted to the purposes to which they 

 are applied. 



Jan. 2. — Mr. R. Wolseley completed his course of Lectures on Mineralogy 

 by the delivery of the fourth lecture of the series. 



Having in his three preceding discourses treated of the peculiar characteristics 

 and properties of various minerals separately, explained their classification, and 

 analysed their constituent properties; Mr. Wolseley, in his present lecture, 

 proceeded to describe those vast repositories in Nature, whence the greater por- 

 tion are obtained, and whence, consequently, so much of the wealth of the coun- 

 try is derived, namely — the mines. These, after a few prefatory remarks, the 

 lecturer divided into three kinds — Salt, Coal, and Mines of Metallic Ores. He 

 entered into an interesting and minute description of the Salt-mines, des- 

 cribed their general depth, and the relative position which they occupy in the 

 crust of the earth, their extent, and the sum of their annual produce, and pointed 

 out the localities of a few of the most celebrated. The general history and des- 

 cription of Coal-mines were next given, and Lodes or Veins described. A mi- 

 nute account was then given of the principal Iron, Copper, and Lead-mines, and 

 of the Mines of precious Metals generally, the strata in which the several ores 

 were found, and the manner in which the mines were worked ; and the lecturer
