grains, in strings, and in the limestones in capricious ramifications 

 some centimetres in width. True veins are the exception. E. Cala- 

 mine, in lenticular masses in the limestones, and more or less mixed 

 with blende, wherever the schists and the limestones have been brought 

 face to face. F. Oxide of tin, as lenticular masses of wood-tin in the 

 upper schists. Gr. Carbonate of copper, seldom workable, in masses 

 both in the schists and limestone and at their junction. H. Iron- 

 pyrites, very common in the schists, in the form of beds, veins, and 

 pockets. Chap. iii. on the origin of the various deposits. Analyses of 

 each kind of ore are given ; and the plate consists of sections illustrating 

 the mode of occurrence of each deposit. G. A. L.

This part of the author's series of studies deals with the fauna of the 



red iron-ore from the Haina mine, near Giessen. The ore occurs in 



Devonian limestone, and has yielded 63 species and varieties* The 



fauna is similar to, but not identical with, that of the StHngoceplialus^ 



limestone of Nassau. One new species is described and figured as 



Amplexus hiseptatus. F. W. R.

Describes certain cylindrical cavities filled with gravel, sand, and 

 clay, found in the neighbourhood of Paris and elsewhere. They have 

 all the characters of pot-holes ; and the author dismisses the theory of 

 their formation by geyscrian ejections, thinking that they were un- 

 doubtedly formed from above. G. A. L.
