if inconsiderable, troubles, slips, or hitches ; and are the same 

 that some geologists have called faults. I have already noticed 

 the main, or 90 fathom dyke, when speaking of the hmestone 

 quarry at Whitley, 8cc. &c." And at p. 26, " It is highly pro- 

 bable it traverses the lead mine district, and produces lateral and 

 valuable metalliferous veins therein." The word basalt never 

 occurs in my description of this fissure. Letter press, p. 287, 

 ^' In many instances, through a fondness for generahzing, or an 

 attachment to theory, authors have bestowed the name of coal 

 basin where it is by no means appropriate. Thus we read of the 

 coal basin of Newcastle, or the coal basin of the Tyne and Wear, 

 though the coal strata of that district are no more in the form of 

 a basin than the metalliferous limestone on which they are 

 understood to repose, or the magnesian limestone which reposes 

 on them." To this I answer, that the numerous sections pub- 

 lished in the Transactions of the Geological Society, prove the 

 coal measures of this district to rise by gentle degrees towards 

 north and south, and more rapidly to east and west ; therefore, 

 these strata must rest in a trough or basin, which by no means 

 is the case with the encrinal hmestone, or magnesian limestone 

 beds. Note, p. 287, *^ Since the two preceding parts of the 

 work were printed, we have seen a paper by Mr. W. entitled, 

 * Observations on the Eastern Part of Yorkshire, published in. 

 vol. V. of the Geological Society's Transactions. In that paper, 

 Mr. W. states, that the coal formation which covers the shale 

 forms a basin. Had that gentleman examined our district 

 himself, instead of attempting to describe it from scraps of 

 information collected from others, he might have avoided this 

 mistake, as well as several other errors into which he has fallen." 

 The observations in question were sent to the Geological Society 

 so long ago as the year 1816, and extracts from them appeared in 

 the Annals of Philosophy for that year, vol. viii. p. 140, and of 

 course, I conclude, must have been known to the Rev. G. 

 Young ; and as that gentleman has more than once honoured 

 me with a call since that period, had he hinted his suspicions of 

 my never having investigated the part of the country where he 

 now resides, I should have acquainted him that several years 

 ago my affairs frequently called me not only to Whitby, but |o 

 Hull, Scarborough, Driffield, Stockton, 8cc. ; and from notes 

 taken on those occasions, together with colliery borings kindly 

 communicated by Mr. Buddie, my paper, which, I am sorry to 

 see appears to have given offence, was chiefly compiled.
