derived st ill more advantage from this valuable accumulation of selections, wliich 
is sMved tVoin anproachinG: the character of a mere compilation by the amount 
of local knowledcje with which it has been intercomminglcd. 
The authorities for the information thus amalgamated with the original matter 
arc for t he most part duly acknowledged and referred to in the text or in foot-notes. 
should, however, have liked to have seen the labours of the Commission 
for the Geological Survey of the Netherlands more promineutly brought for- 
ward by the author, especially in respect to the geology and palfcontology of 
the Limburg region. M. Bosquet's elaborate memoirs on the cretaceous Crus- 
tacea and Brachiopoda of Limburg appear to have escaj)ed 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^ jyrimiffe- 
niiis, Rhinoceros, &c., and the tiint weapons of primajval men (p. 2) ; 2, gravels 
and erratic boulders (p. 7). B— Tertiary : 1, Bolderian-beds (p. 12); 2, 
Bupelian-bcds (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 the 
details of a section taken near Fauqueniont ; 2, Craie de Schaasberg (p. 52) ; 
3, Marne de Kunraad ; -1, Marncs de Simpelveld and Vetchau (p. 64) ; 5, 
Craie siUceuse 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, RexicnK', (p. 108) ; 11, 
Craie blanche a silex noirs et marnes sans silex (p. 136); 12, Sables vert a 
BehiiiniteUa quudrata (p. 161) ; 13, Couche de cailloux roiiles et sable d'Aix- 
la-Chapelle (p. 181). D— The Coal-formation (p. 185). 
vVs we have said before, the author's industry has accumulated a mass of 
valuable facts relating to the deposits above enumerated, while his knowledge 
of t he 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 palajontological acquii e- 
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. 20 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 m the following succession : — 
Metres. 
1. Vegetable earth 100 
2. Loess 1-00 
3. Rolled pebbles 3 00 
4. Quartzose ochreous sand, of a yellow colour, with streaks 
of strong red 10 00 
5. Craie tuffeau 1'50 
6. A stratum very rich in fossils, chiefly Hemiaster prunella, 
Rln/?icolithics Buchii, Rh. Beheyi 0"60 
7. Craie tuffeau 1-00 
This bed is stated to attain a thickness of twelve metres at Geul- 
hem, half a league from Fauquemont, where the fossils are com- 
inonly presented in the form of casts, and Herr Binkhorst notices 
in it an Ammonite which resembles A. perlernalis, Roem., but which 
he considers a new species, and as probably being the last of those 
ceplialopods.
