THE many memoirs, and the numerous letters to the editors from 

 active and well-known geologists and mineralogists, make 

 this as rich as any former volume in original matter; whilst the 

 bibliographical register of published memoirs, and the multitudinous 

 abstracts of books and papers, treating of mineralogy, crystallography, 

 mineral-chemistry, geology, and palaeontology, render the Nenes Jalir- 

 buch indispensable to working geologists of every turn of mind, who 

 wish to keep up with the current literature of their science. As 

 original memoirs they will find, in Palaeontology : — E. von Eichwald
