derived still more advantage from this valuable accmmilatiou of selections, ^vllicll 

 is saved from approaching the character of a mere compilation by the amount 

 of local kno^\*leage wiih. wliich it has been inter commingled. 



The authorities for the information thus amalgamated \Tith the original matter 

 are for the most part duly acknowledged andreferred to in the text or in foot-notes. 

 ^Ve should, however, have liked to have seen the labours of the Commission 

 for the Geological Survey of the Netherlands more prominently brought for- 

 ward by the author, especially in respect to the geology and palaeontology of 

 the Limburg region. M. Bosquet's elaborate memoirs on the cretaceous Crus- 

 tacea and Brachiopoda of Limburg appear to have escaped recognition in this 

 way, although the results of M. Bosquet's labours are embodied in the work. 

 The following are the deposits described in this first part : — 



A — Quaternary: the Loess or Lehm, with its remains of Elephas primige- 

 nifis. Rhinoceros, &'C., and the flint weapons of primaeval men fp. 2) ; 2, gravels 

 and erratic boulders (p. 7). B — Tertiary : 1, Bolderian-beds (p. 12) ; 2, 

 Kupelian-beds (p. 15); 3, Tongrian-beds (p. 17). C — Under the head "Cre- 

 taceous" we have accounts of the 1, Craie TufFeau (p. 25), illustrated by tlie 

 details of a section taken near Fauquemont ; 2, Craie de Schaasberg (p. 52j ; 

 3, Marne de Kunraad ; 1, Marnes de Simpelveld and Vetchau (p. 61) ; 5, 

 Craie siliceuse de Kunraad, Benzenraad, et Simpelveld (p. 71) ; 6, the strata 

 near Jauche in Belgium (p. 79) ; 7, those at Jondrain (p. 83) ; 8, those at 

 Ciply (p. 85); 9, Sand-pipes and channels (98); 10, Resume, (p. 108); 11, 

 Craie blanche a silex noirs et marnes sans silex (p. 136) ; 12, Sables vert a 

 Beleniititelht quadrata (p. 161); 13, Couche de cailloux roules et sable d'xiix- 

 la-Chapelle (p. 181). D— The Coal-formation (p. 185). 



As we have said before, tlie author's industry has accumulated a mass of 

 valuable facts relating to the deposits above enumerated, while his knowledge 

 of the localities and his method of carefully collecting the fossils have given ad- 

 ditional value to his remarks. Some of his catalogues of fossils appear to be 

 enriched by the local lists of Bosquet and others ; and we must judge of them 

 in accordance with his own modest statement of his palaeontological acquire- 

 ments. In the resume at page 108, in the general considerations at page 220, 

 in the preface, and in the notes at pages 231-267, the reader will find many in- 

 teresting observations and extracts illustrating various topics discussed in the 

 book. 



In Plate III. of the illustrations, and at p. 29 of the work, the section of 

 the Cretaceous rocks surmounted by Tertiary deposits at Heunsberg, near Fau- 

 quemont, is given, presenting to view the strata in the following succession : — 



Metres. 



1. Vegetable earth 1-00 



2. Loess 1-00 



3. Rolled pebbles 3 00 



4. Quartzose ochreous sand, of a yellow colour, with streaks 



of strong red lO'OO 



5. Craie tuffeau 1*50 



6. A stratum very rich in fossils, chiefly Hemiaster pnmella, 



Rhjncolithm Buchii, Rh. Beheyi 0*60 



7. Craie tuffeau, I'OO 



This bed is stated to attain a thickness of twelve metres at Geul- 

 hem, half a league from Eauquemont, where the fossils are com- 

 monly presented in the form of casts, and Herr Binkhorst notices 

 in it an Ammonite which resembles A. pedernalis, Roem., but which 

 he considers a new species, and as probably being the last of those 

 cephalopods.
