    strata incline at a very small angle from the perpendicular, and are of very peculiar construction. The stone itself is full of druses, and the most compact is full of small holes of all shapes similar to those in bread. Madrepores of various kinds abound, as m. ananas, m. musica, &c., all which are quite foreign to their neighbours in the blue limestone on the west. The whole of these rocks are stratified, but have very much the semblance of hot matter suddenly cooled in water. Fifthly, Farther to the east, and at nearly the same distance, he would examine the continuation of the group of magnesian limestone at Barrow-Hill, Gracedieu, and Osga- thorpe, arranged nearly in horizontal layers. Sixthly, To the east, he would suddenly, after passing the coal measures, find a short border of red marl, backed by the vertical strata of sienite of Charnwood Forest. Should he prolong his route in this line, about ten miles after passing the Charnwood Hills, he would come upon the lias flanking the east bank of the Soar, the range of which stratum across the kingdom, Charnwood Forest seems not to have disturbed. Seventhly, Upon taking a southerly course, he would soon pass the outcrop of the coal strata and enter upon a marl district ex¬ tending from Bagworth by Bosworth, Congerstone, Twycross, and Appleby. Eighthly, By turning in a westwardly course, he would find conglomerate rock and sandstone at Measham and Oakthorpe. And lastly, to the north¬ west, quickly passing the coal outcrop, he would arrive at the horizontal sandbeds and grit bordering the east bank of the Trent, capped with many conical mounds and extensive tracts of marl and red earth. In order to shew the difficulty of adopting any System to be applied practically, the following details of such facts and phenomena as appear to deserve the consideration of the Geologist, have been observed and collected at one of the principal workings in the Ashby Coal-Field, for the purpose of bringing them under his attention so as to enable him to endeavour to
