248 Chronicles of Science. [ April, 
and importance, namely, the discovery of three species of Nummu- 
lite in the Cretaceous rocks of Palestine ; one of these is a variety 
of a species known to occur in the Eocene rocks of Europe, and 
cited also from Asia Minor and Kurdistan; one is an American 
species, said to occur in the Cretaceous beds of that continent; and 
the third, occurring in the Hippurite-limestone of Wadi Jés, is a 
new species. 
Two works of great importance in Alpine geology have appeared 
within the last few months; but they are so extensive that no 
adequate idea of their contents can be given in this Chronicle. The 
larger work, by M. Favre, is entitled ‘ Recherches géologiques dans 
les parties de la Savoie voisines du Mont Blanc.’ It consists of 
three octavo volumes of text, and a folio atlas of 32 plates, and is 
an exhaustive geological account of the Mont Blanc district. The 
smaller work plays the same part for the Swiss Jura, though not so 
completely. Its title is ‘Essai géologique sur le Jura Suisse,’ by 
Dr. J. B. Greppin. 
The ‘Geological Magazine’ for the past three months has con- 
tained many articles of interest, including the continuation and 
conclusion of Mr. Belt’s memoir “On the Lingula-flags,” which 
the author treats as Upper Cambrian, and which he divides into 
six stages. Dr. Sterry Hunt has replied to Mr. David Forbes’s 
criticisms on his Lecture at the Royal Institution, and the latter 
author has printed a rejoinder to the former's reply. One fortunate 
circumstance in this controversy is that students of chemical geo- 
logy may, by reading these articles, become acquainted with many 
facts which they might otherwise lose sight of. Mr. Carruthers 
has a useful article “On British Graptolites,” with an analytic key 
to the genera, which will be of great service to those endeavouring 
to master the subject. Mr. Maw has very cleverly found—or, 
rather Mr. Kippist has—a closer parallel to the much-discussed 
flower-like forms considered by Heer to be referable to Porana, and 
the first-named paleontologist has published hig conclusions in a 
note, entitled “On a flower-like Form from the Leaf-bed of the 
Lower Bagshot Beds, Studland Bay, Dorsetshire.” Finally, Mr. 
Ruskin has given another of his papers “On Brecciated Con- 
cretions.” 
PRocEEDINGS OF THE RoyaL GEOLOGICAL Socrety. 
The Supplement-number to the volume of the Society’s Journal 
for last year contains but two papers, both of great length and of 
considerable importance to British geology. The first paper is by - 
Mr. Charles Moore, “ On Abnormal Conditions of Secondary De- 
posits when connected with the Somersetshire and South Wales 
Coal Basins; and on the Age of the Sutton and Southerndown
