country about Charnwood Forest — very ancient rocks certainly, 

 These Malvern hills meet us, on our journey from Oxford, like a wall, 

 and differ in every way from all the strata which surround them." 

 (p. 59.) 



Thus we have in the Malvern ridge of very old rocks, gneiss, 

 Granite, Syenite, Diorite. Besides these, which are all well-marked 

 rocks, we have frequently greenstones, felspatho-hornblendic, or 

 felspatho-augitic compounds, the felspar not being orthoclase, and 

 not distinctly crystallized. Felstone, Quartz-rock, Serpentine, and 

 mineral veins composed of Mica, Talc, Epidote, Graphite, Copper 

 pyrites, and Copper carbonate, and sulphate of Baryta. 



The second period is formed by the Cambrian rocks, represented 

 by the Hollybush sandstone and the black shale yielding Trilobites 

 of the Primordial type and other fossil-remains. 



The Silurian, Devonian, Carboniferous, Permian, Triassic, Ehsetic, 

 and Liassic deposits are successively dealt with in greater or less 

 detail, according to their development within the area treated of by 

 the author. 



But the great feature of the work, and that in which is displayed 

 for the first time the results of Professor Phillips's latest and most 

 important pal^ontological labours, is comprised in some three hun- 

 dred illustrated pages (chaps, xi.-xiv.), embracing the author's "Bath 

 Oolite Period." In it we are not only made acquainted with the hosts 

 of the Invertebrata — corals, worms, mollusks, insects, crustaceans 

 — met with in the Oolitic rocks, but with numerous fishes, some 

 half-dozen of small mammalia (from Stonesfield)^ and that grand 

 assemblage of reptilian remains for which Oxford has so long been 

 famous, comprising, Plesio-, IcTitJiyo-, Teleo-, Steneo-, and Dako- 

 saiirus ; the flying BhampTiorliynchus ; several Cheloniee ; the great 

 land-dwelling Megalosaurus, and that mightiest of ancient lizards, 

 the giant Cetiosaurus, with the remains of which the name of Prof. 

 Phillips will long be associated as its indefatigable investigator and 

 restorer. 



Space would fail us in which adequately to describe this ancient 

 denizen of the Thames Valley. The earliest discovery of remains of 

 Cetiosaurus dates back as far as 1825, to which subsequent additions 

 from time to time were made by Dr. Buckland and others ; but it 

 was not until 1868 that the present discoveries of Prof. Phillips 

 were commenced by the finding of a gigantic femur sixty-four inches 

 in length, the precursor to the grand series of bones laid bare in 

 1870, comprising remains from almost every part of the skeleton. 

 Some of the most striking of these, such as the vertebrse, ribs, 

 scapulee, humeri, ulnfe, pelvic bones, femora, tibia, etc., are drawn, 

 one-tenth the size of the originals; and when we remember the 

 hundreds of fragments from which these huge bones have been built 

 up, we cannot but admire the skill and patience brought to bear 

 upon the task by Professor Phillips and his assistant, Mr. Henry 

 Caudel. 



Taking the lowest of the various estimates of the size of this huge 

 reptile (arrived at by measuring and comparing its bones with those
