and improved edition of his father's map of Auvergne ; — a work 

 which is still spoken of with admiration, for its fidelity and skillful 

 construction, by all who explore that country. But the labors of 

 the younger Desmarest were principally bestowed upon the other 

 parts of natural history. We possess in our Library, extracted 

 from various journals, and presented us by the author, his "Notes 

 on the impression of marine bodies in the strata of Montmartre," 

 published in 1809; his "Memoir on the Gyrogonite," published 

 in 1810 ; to which he added, 1812, the recognition of the analogy 

 of this fossil with the fruit of the Chara, pointed out by his 

 brother-in-law M. Leman ; his review of a work by M. Daudebard 

 de Ferussac, on the Fossils of Fresh v\rater Formations, in 1813 ; 

 his memoir on Two Genera of Fossil Chambered Shells, in 1817 ; 

 and his " Natural History of Proper Fossil Crustaceans," published 

 in 1822 along with M. Brongniart's "Natural History of Fossil' 

 Trilobites." In the " Dictionnaire d'Histoire Naturelle," the arti- 

 cle JMalacostraces, which contains a complete account and classi- 

 fication of Crustaceans, is by M. Desmarest, with others on the 

 same subject. In this work all the articles on Crustaceans had 

 originally been assigned to Dr. Leach ; but when the lamented 

 illness of that distinguished naturalist prevented his finishing this 

 task, it was committed to Desmarest, who carefully studied the 

 labors of his predecessor ; and, with most laudable industry and 

 self-denial, made it his business to follow his method as closely 

 as possible. He also published a separate work on Crustaceans 

 in 1825. 



Count Kaspar Sternberg was one of those persons, so valuable 

 in every country, who employ the advantages of wealth and rank 

 in the cultivation and encouragement of science. He belonged 

 to a younger branch of one of the best and oldest families in Bo- 

 hemia ; and was closely connected with the persons of most eleva- 

 ted station in that country. He was born the 6th of January,, 

 1761, and received a distinguished education at Prague ; not only, 

 as was then common among the Bohemian nobility, through pri- 

 vate tutors, but by following the public course of the university. 

 He was created Canon of the Chapter of the metropolitan church 

 at Ratisbon, which, obliging him to receive the lower degree of 

 holy orders, bound him to celibacy. At Ratisbon, then a consid- 

 erable place, and the seat of the Diet of the German empire, he 

 formed friendships with several eminent persons, and especially
