M. Bosquet also has determined several species of Entomostraca 

 and Foraminifera, all of which are Tertiary, 



The authors have assiduously studied the geology of the region, 

 and made a number of sections, in order to learn whether any dis- 

 turbance of the strata has produced such a peculiar arrangement, 

 and whether the Limestone is really overlain by the Landenien beds. 

 They have, however, come to the conclusion that the succession is 

 normal ; but for the discussion we must refer the reader to their 

 original paper. — L'Institut, 28th Feb., 1866.

THIS Memoir, on the Paleeontology of the Jurassic and Cretaceous 

 formations of Noiih- western Germany, of which the first part 

 only has appeared in one of the late numbers of the well-known 

 " Palseontographica " of Dr. W. Dunker, is intended to illustrate 

 the new or little known fossils of these formations. The first part 

 contains six plates, with full descriptions and synonyms, of thirty- 

 three Jurassic Ammonites. The author appears to have carefully 

 consulted the various works bearing upon the subject, so that when 

 his book is completed, it will form a useful addition to our 

 Palseontological literature. — J. M.

THE great mass of readers, now-a-days, anxious though they are 

 to be intelligently acquainted with science, have not the time 

 nor the patience required to master its technical details, and conse- 

 quently are unable to use the most elementary manual that one would 

 put into the hands of a young student. Those who have attained 

 some proficiency in a science are apt to overlook this, and when 

 seeking to entice friends into the studies which have given them so 

 much delight, are frequently surprised to find that the attractive and 

 simple manual, after a strong effort, is at length laid aside as dry and 

 learned. When one has "finished his education," he will never 

 learn any new science by beginning with a manual, unless with an 

 amount of determination and perseverance which are seldom met 

 with in these degenerate days. Grown up readers must learn a 

 science first through popvilar sketches ; these may then become the 

 first steps to the technical handbook. So evident is this that book- 

 shops are full of popular guides to Geology, Botany, Zoology, etc.
