Russia's Contribution to Science. 229 



educated men in the world, is the real creator of the mineralogical 

 museum in AIoscow and author of many researches. He investi- 

 gated the mines of Austria and Germany in 1894 during which 

 trip I had the privilege of accompanying him and shall never 

 forget his enthusiasm, energy and perseverance. He worked at 

 that time from morning till late in the evening, collecting minerals, 

 visiting mines, museums, art galleries and points of interest and 

 in the evening when I was totally exhavisted and ready to fall 

 asleep, he would open some new treatise on history of art, or 

 civilization or sociology and read imtil late into the night. Later 

 he took part in the liberating movement of Russia, was member 

 of the Imperial Council, and quite recently member of the Provi- 

 sional Government, remaining in Petrograd at his post when 

 the Kerensky Government was fighting its last battle. A man of 

 the tenderest heart, a friend of youth, he lived through most 

 trying experiences during the student revolt, enduring discom- 

 fitures and incurring insult for extending with fatherly love his 

 protection to persecuted students. 



Alexander Alexandrovitch Inostrantzev is perhaps the most 

 distinguished Russian geologist, born in 1843. He travelled a 

 great deal throughout European Russia, the Caucasus and the 

 Ural mountains and published many works among which I cannot 

 omit mentioning his two volumes of Materials for the Geology of 

 Russia, published in 1869, his Geological Investigations of the 

 North of Russia, published in 1872, his subdivision of the stone 

 age into periods, published in 1880, and his Treatise of Geology, 

 published in 1885 and reprinted several times w'ith additions and 

 revisions. Inostranzev was for years president of the geolog- 

 ical section of the St. Petersburg Society of Naturalists and 

 president of the Russian Anthropological Society. He worked 

 up the geological collection brought by Przewalsky, Potanin, 

 Pievtzov and others, and made the St. Petersburg Geological 

 Museum one of the best in Russia. It may be interesting to 

 recall to memory the fact that the Philadelphia Academy of 

 Sciences elected Inostranzev corresponding member. 



One more name should be mentioned in connection with geolog- 

 ical and mineralogical sciences. It is the distinguished name of 

 the unfortunate Dokutchaeff, who did so much for the elucida- 

 tion of the nature of the black earth in Russia, created a school 

 of learning, founded a museum of natural science in Poltawa and
