 observations upon a large series of calcite crystals, and the de- 

 scriptions are further elucidated by many excellent figures. His 

 attention was especially directed to those cases in which the for-

14. Upon the Chemistry and Composition of the Pore 



-rucks of Japan; by Henry Wurtz.— Dr. Wurtz has 

 published, in a recent number of the American Chemist, a paper of 

 some length upon the porcelain-making of the Japanese, prepared 

 by him in his capacity as Judge in one of the departments of the 

 Centennial Exhibition. He gives a description of the occurrence 

 of the materials in Japan, and the methods employed in the prepa- 

 ration of the porcelain from them. The chemical composition of 

 err different varieties and the man- 

 ufactured products are also given at length in a series of analyses.
