The original Specimen of the unique Skeleton of this species of Plesiosaurus, no ,

DEDICATED TO THE REV. WM. BUCKLAND, D.D., F.E.S., & L.S., 



PROFESSOR OF GEOLOGY AND MINERALOGY IN THE UNIVERSITY OF OXFORD. 



These Models are constructed of various kinds of Wood, fitted together from 

 actual Measurements of the Strata in tiic Coal and Lead Mining Districts of tk 

 North of England. The upper part of each Model represents the surface of the 

 ground ; the sides exhibit four vertical sections, each of which corresponds wth the 

 sections usually drawn in Geological Works, and the base of each Model represents a 

 horizontal plane at a certain depth under the s-u^face, according to scale. 



To sindents in Geolog}^, and others interested in Mineral Districts, these Models 

 afibrd a clearer idea of Geological Phenomena than ordinary plans and sections, pre- 

 senting a fac-sim.ile of the objects represented, which can be studied in every variety 

 of position, and thus exhibit and explain the subterranean, as well as surface relations 

 of the various Strata, Beds of Coal, and Mineral Veins.

It may be proper to observe, that the train of investigation which is required to 

 study these Models is wholly apart from the theoretical researches which extend to 

 the original formation of th(^ rocks^ and is confined to such facts as are open to every 

 day observation, and of which no doubt can possibly exist. 



The description of the Models can be had separate, price 1^-. M.
