106:(1880-1881), and he described his observations and experiences in his 1884 travelogue. His experimental work involved the synthesis of minerals at high pressure and temperature including nepheline, pyroxenes, micas, and zeolites. He examined the effects of remelting and recrystallization and these went into his 1890 textbook on general mineral chemistry. He studied water of crystallization in the zeolites, examined the physical and chemical laws involved in silicate melting. He later examined the physical properties of silicates and other minerals and suggested theories to explain the nature of electrical conductivity by crystals. In 1906 he published a book
