many Points m the Frith of Clyde. 253 



These are a few of the observations which I was enabled to 

 make during my short stay in Arran, as far as regards position, 

 The others must be deferred to some future opportunity. 



I may add, however, that from a paragraph which I sent to some 

 of the Glasgow newspapers on my return, stating a few of these 

 glaring blunders, I have the satisfaction to learn that on a petition 

 or memorial afterwards prepared from those interested in the pros- 

 perity of the trade of the river Clyde, Government have engag-

 and part of the adjacent lochs, and I should be happy if these 

 remarks would draw the attention of men of influence connected 

 with Scotland to memorialize Government to induce- it to grant 

 a tenth part of those employed on the Irish survey, that is, 120 

 men and officers, to continue the survey of Scotland, under the 

 able superintendence of Colonel Colby, where it might be thought 

 most advantageous for the prosperity of the country, and bene- 

 ficial to its maritime interests.

THE crystalline slaty rocks occupy an immense tract of 

 country in European Turkey, as they form the following chains, 

 viz. the great ranges of the Tschardagh and Despotodagh ; the

 rida and Castoria ; the Pindus ; the Olympus ; in Servia, the 

 Jastrebacz, the Temnitscha-Planina, and the western borders 

 of the Morava valley higher than Tagodin ; and in Wallachia 

 the chain separating that country from Transylvania and 

 the Bannat. These rocks also, chiefly under the form of mica 

 or talc slates, occupy considerable tracts between the Timok 

 valleys and the defile of the Danube ; then west of the Pristina 

 plain ; around Kacsanik ; in the Karadagh ; around Egri- 

 Palanka ; between that town and Karatova ; south of Kosten-
