Coprolite-beds (‘Cloake’), besides others of less importance, namely: 
1. Below the Lettenkohlensandstein. 2. Between the horizon of 
Beaumont and the Keuper-gypsum. 3. In the Keuper-sandstone (0). 
4, In the Koéssen beds (Tabingen) immediately below the Lias. 
These deposits (Cloake), he observes, have all the same character ; 
they form great layers in the beds in which they occur, and contain 
teeth, bodies, and scales of various Fishes and Reptiles, mixed and 
cemented together with Coprolites.—H. M. J.

ESIDES the usual notices of Mineralogical, Geological, and 
Paleontological memoirs, the last number of the ‘Jahrbuch’ 
contains the following papers :— 
1. Vorlaufiger Bericht tber krystallinische Silikatgesteine des 
Fassathales und benachbarter Gegenden Siidtyrols, von Herrn T. 
Scheerer. (Preliminary notice on the Crystalline Siliceous rocks of 
the Fassathal and neighbouring districts of South Tyrol.) 
In this paper the author divides the different rocks occurring in 
the district under consideration into two great classes, namely, the 
Hochsilicirte Gesteine (or Plutonites) and the Niedrigsilicirte Ge- 
steine (or Vulcanites). These classes are again subdivided, so that 
all the rocks of the Fassa Valley are arranged as follows :—
