classical quarries a visit onkis journey to or from Munich, where, in 
the National Museum, ke will find a magnificent Collection of tke 
type specimens of von Meyer’s, Schlotheim’s, Oppel’s, Zittel’s, and 
many otker celebrated palaeontologists’ figures and descriptions of 
Lithographie limestone fossils. 
“ Düring the succeeding Cretaceous Period, a great part of Switzer- 
land was dry land, the sea covering cliiefly the low ground from the 
Lake of Constance to the Lake of Geneva ; its northern coast ran 
nearly in the direction of Schaffhausen by Aarau and Soleure to 
Bienne, and thence extended further westward, quitting the limits of 
Switzerland. The sea no doubt covered these districts, where 
strips of marine Cretaceous deposits are frequently met with, which 
were formerly connected together. The Southern shore of the 
Swiss Cretaceous sea is shown generally by a line drawn from 
the Lake of Wallenstadt to Altdorf, the Lake of Brienz and Bex ; 
but there are numerous and deep inlets bringing the sea into the 
interior of the Alps, as in the Canton of the Grisons, where the 
Calanda and part of the chain of the Kalfeusen are formed of Creta- 
ceous rocks.” (p. 176.) 
Passing from the Cretaceous formation to the Tertiary Period, we 
have in the Eocene slate-quarries of Matt, in the Canton Glaris, the 
most important Swiss locality for the remains of fossil fishes. Dry 
land was at no great distance, as evidenced by the fossil remains of 
two species of birds found at Matt. These beds must have under- 
gone great pressure, as they closely resemble the Cambrian slates of 
Bangor in tkeir general appearance, tkougk of a much darker hue ; 
they are also largely quarried for the same economic purposes as our
