lioMiii;; a saiulstone cast of tlio medullary cylinder, 2 incheH in diameter. The 

 trunk spreads at lusc to :) feet, and extends its Stn/maria roots on the roof of 

 the coal. A prostrate and flattened trunk of Lepulojloi/ns was found imme 

 diately below it. 



If). Extracted in 1870. Dia meter, I foot inches; basal part, about a foot 

 thick and partially compressed, alone seen; the uppt " part having been 

 removed by the sea. The [)roduetive matter in its base f.flbrded 13 skeletons 

 oUh'mhrrpcton, I/i/Iononuts, iri/ln'peto)i,!ind Fritsclua, besides Millipedes and 

 PtipiP. 



'20. PJxtracted in 1878. Diameter, I foot; distance from No. 18, 120 feet; 

 Filled with shaly matter not productive. 



21. Extracted In 1878. Diameter, 1 foot 8 inches; heij,dit remaining, 4 feet; 

 distant from No. 20 2() feet. Aliout 5 inches of carljonaceoua matter in the 

 base, containing remains ef Ifi/lnuoiuNs, Ili/lcrj)('ton and Siitilcrjx'ton. This 

 tree is much crushed by lateral pressure at the base, and the bones obtained 

 from it were in a fragmentary condition. 



22. Extracted in 1878. Diameter, 2 feet 3 inches; height remaining, 3 feet. 

 Filled with sandstone to base, without fossils. 



23. Extracted in 1878. Diameter, I foot inches; base only preserved. Close 

 to No. 22. Some carbonaceous matter in the base believed to be productive, 

 but accidi'utally mixi'd with tlie contents of No. K!. 



24. Fxtraeted in 1878. Diameter, 1 .") inches; height remaining, 3 feet; dis- 

 tant 8 feet from No. 2:!. A little carbonaceous m.itter in hard lamimo of 

 sandstone in base. Contained a lew scattered scales and bones of Deudrcr- 

 pttoii, and some jointed objects supposed to be insect larv;e. 



2"). Not extracte<l. About IS inches in diameter, and several feet in length. 

 Distant loO feet from No. 24. Thistruidc is prostrate and partially ilatteiied. 

 It is visible only at very low tidis, and I had no opportunity to extract it. 

 Being prostrate, and so far distant from No. 24, it may possibly mark the 

 limit of the erect trees in this direction. 



It will bo observed that ot the erect trees catalogued above, ten were altogether 

 unproductive. Of these, some had evidently been broken down and filled while the 

 art'a was still submeiged. Otiun's, on the contrary, had remained inaccessible to 

 animals till suddenly fill(>d by the final iniiption of sand. The intermediate conditions 

 were those favourable to the entombment of land animals. Fifteen trees were mon; or 

 less productive: a remarkable |iroport!oii when the combination of circumstances 

 necessary to this result is considered. The greater \YMt of the remains have however 

 been obtained from nine or ten of the tives catalogued; but sonu; of the others were 

 only bases of trunks from which more |>i'oiliictive portions may have been removed by 

 the sea. Tlie more pioductive trees arc intermixed with the others, and there seems
