35G On Mineralogical Surveys. 



been published by Smith, and Greenough. At present Mr. 

 De la Beche is engaged in colouring geologically the maps 

 connected with the great Trigonometrical Survey. The geo- 

 logy of Scotland has also been minutely examined, and 

 lately a map was published from materials collected by 

 MacCulloch, most of which, however, were pillaged from 

 Professor Jameson, who for the last 12 or 14 years has had 

 in his possession materials collected, from personal examina- 

 tion, for a geological map, but his other numerous avocations 

 have as yet prevented him from making use of them. In 

 1838 he called the attention of the Wernerian Society to 

 the great want of a regular survey of Scotland, which led 

 to the appointment of a Committee of the Society, which 

 was ordered to communicate with the Royal, and Highland 

 Societies, and to request of them to draw up memorials, 

 petitioning government to recommence the Trigonometrical 

 Survey, which was immediately done ; and upon the res- 

 pective memorials of each of the Societies being transmitted 

 to government, an order was given for a certain number 

 of the individuals engaged in the Irish Survey to be drafted 

 to Scotland, and before we left that country, Col. Colby, 

 the chief engineer, had arrived in order to see the survey 

 properly begun; we may therefore hope soon to see finish- 

 ed this important national work. In laying the report before 

 the Wernerian Society, Professor Jameson accompanied it 

 with a statement of the points of greatest importance to be 

 attended to in the mineralogical department, which however 

 he has not as yet published, and considering that it might 

 be of great importance to those engaged in drawing up 

 topographical accounts, we have been induced to give an 

 account of the method proposed.
