14 PROCEEDINGS OF THE SAINT LOUIS MEETING 



University. In 1895 he was appointed Assistant Professor of Geology 

 and Mineralogy in the College of the University, and in 1903 full Pro- 

 fessor of the same subjects — a position vrhich he occupied until a few 

 months before his death, when his failing health led him to resign. 



After Doctor Brown left the Geological Survey of Pennsylvania he 

 carried on scientific researches covering a wide field, including geologj^ 

 mineralogy, paleontology, botan}^, and the subject of crystallography in 

 relation to biology. Though his early education was that of a mining 

 engineer and his first teaching position at tlie university was in mining 

 and metallurgy, yet most of his research work was in pure science. In 

 1893 he went to the western part of the country with Prof. E. D. Cope 

 to make paleontological studies in the Dakotas, Kansas, Texas, and Okla- 

 homa, and somewhat later he made other trips West on similar work. In 

 1902 he visited Labrador, and in later years made trips to Panama, 

 Jamaica, Antigua, and other places in the West Indies, where he made 

 important geological and paleontological researches. 



The best known of Doctor Brown's original work was "The Crystal- 

 lography of Hemoglobins," published in connection with Prof. E. T. 

 Eeichert, of the University of Pennsylvania, by the Carnegie Institution 

 of Washington in 1909. This remarkable work attracted wide attention 

 at the time, both in America and abroad. From the standpoint of crys- 

 tallography as well as of biology, it was an extremely valuable research 

 and its thoroughness marked a distinct step in advance of anything that 

 had previously been done on allied subjects. 



At the time the United States Government was beginning the con- 

 struction of the Panama Canal, Doctor Brown was one of the first to 

 recognize the importance of a study of the geologic structure of the re- 

 gion. He visited Panama in 1910 and published several papers on the 

 geology and paleontology of the country about the Gatun Dam. He also 

 visited Jamaica, Antigua, and other places in the Caribbean Sea, where 

 he made important studies of their geology and paleontology. Some of 

 this work was done in connection with Prof. Henry A. Pilsbry, of the 

 Academy of Natural Sciences of Philadelphia. 



Doctor Brown had been a member of the Geological Society of America 

 since 1905, and though his ill health prevented his attending many of 

 the annual meetings, yet he always took much interest in its work. The 

 last meeting he attended was that in Philadelphia in 1914, when he took 

 a keen interest in trying to make it a success. For many years he was 

 an active member of the American Philosophical Society and of the 

 Academy of Natural Sciences of Philadelphia. He was one of the secre- 

 taries of the American Philosophical Society from 1908 to the time of
