of a bird with teeth in sockets, like some of the higher reptiles. In 

 addition to these we must not omit to record the labours of Newberry 

 among the Fossil Fishes ; of Hall, Meek, Billings, among the In- 

 vertebrates ; of Lesquereux and Dawson among the Fossil Plants. 



Nor have the labours and publications of European geologists and 

 palaeontologists been overlooked or ignored by the author. 



Such are briefly the vast mass of additional geological and palae- 

 ontological materials, the essence of which Professor Dana has 

 laboured to incorporate in the New Edition of his most excellent 

 text-book. The volume was originally so large (798 pp. royal 8vo.), 

 that it could hardly, consistently, have been made more bulky, yet 

 thirty additional pages have been added to the new edition, and the 

 author tells us " the work has been, for the most part, rewritten." 



If we were to take exception to anything in the book before us, it 

 would be the weight (3 lbs.), which is very tiring to the wrists. We 

 are disposed, on this account, to advocate the division into 2 vols, 

 for all books weighing over 1|- lbs. 



As a suggestion for a future edition, we would ask that a couple of 

 pages of text should be placed at the end of the volume, immediately 

 next to, and in explanation of, the physiographical (folding) chart of 

 the world. This could very well be done without increasing the 

 bulk of the volume, as three blank leaves (= 6 pages) are inserted at 

 the end of the book. 



We hardly think the " Pre-historic Man from the Cave of Mentone," 

 (See Geol. Mag. 1872, Vol. IX. pp. 272 and 368), which forms the 

 frontispiece to the New Edition of Prof. . Dana's work, is of sufficient 

 antiquity to merit so much importance. There is always an element 

 of error to be allowed for in correlating the human remains in 

 caverns with those Rhinoceros, Ursus spelaus, and other Mammalia 

 now extinct in Europe. 



The illustrations throughout the book are most excellent, but they 

 are chiefly selected from American types. 



We heartity recommend this New Edition of Dana's Manual of 

 Geology to the notice of our readers. 



II. — Eevue de Geologie, par MM. Delesse et De Lappaeent. 



(Paris, 1874.) 



THE Eevue de Geologie, which is reprinted from the Annates des 

 Mines (tome iv. 1873), forms the eleventh volume of the 

 Records of Geological Research prepared by MM. Delesse and De 

 Lapparent, and contains notices and abstracts of various papers 

 published in different countries during the years 1871-72. It is 

 compiled with the same care as the previous volumes, and, inde- 

 pendently of the resume of the memoirs noticed, is a useful addition 

 to geological literature. The matter is arranged under five different 

 heads : — general, lithological, historical, geographical, and dynam- 

 ical geology. The lithological section is fully treated, and contains 

 the more recent observations on the composition, structure, and 

 classification of rocks. J. M.
