Fischbacli in Visperthal afforded the crystal for the pyramid 

 of Marsfeld, made in 1797. This block, which is a cluster 

 measuring three feet in diameter and weighing over eight hun- 

 dred i)ounds, is now in the Museum of Natural History, at Paris. 



The neighborhood of Mt. Blanc yields beautiful, clear crystals, 

 the preparation of which for sale gives lucrative employment to 

 the inhabitants of the vale of Chamouny. 



At Galenstock, above the Tiefengletscher, a most remarkable 

 deposit was found in a granite cave, which yielded over one 

 thousand crystals of from fifty to three hundred pounds" weight, 

 but unfortunately of a smoky color. The finest of these crys- 

 tals, weighing one hundred and twenty-five pounds, and called 

 the President, is in the celebrated collection of Mr. Clarence S. 

 Bement, of Philadelphia. Of the others, perhaps the best are at 

 Berne, Switzerland — one called the Grandfather, weighing two 

 hundred and seventy-six ]-)ounds, and another, known as the 

 King, of two hundred and fifty-five pounds' weight. 



A crystal of thirty-eight centimetres in height and nine centi- 

 metres in diameter, from Savoy, is now in the Dresden Green 

 Vaults. 



In Japan, nineteen mines are now being worked for quartz and 

 rock-crystal. The latter material is found in large clear masses 

 in the mountains on the Island of Niphon, Fusiyama, and in the 

 granitic rocks of central Japan, the principal veins being near 

 Kami; but is also found among the gravel beds, where transpa- 

 rent masses that would furnish perfect spheres six inches in dia- 

 meter have been dug out. Some suppose, however, that much of 

 the Japanese crystal is procured from China, and, from state- 

 ments made to the writer by members of the Corean Embassy 

 that recently visited us, it seems probable that the peninsula of 

 Corea has furnished some of the material for these Japanese 

 objects. It was further learned that there are at present twelve 

 workers of crystal in Corea.
