JOHN BELL HATCHER.' 

 BoRX October 11, 1861. Died July 3, 1904. 



The Editor of the Amials of the Carnegie Museum, Pittsburgh, 

 Pennsylvania, U.S., records with deep regret the death, on July 3rd, 

 1904, of his trusted associate, Mr. John Bell Hatcher. 



Mr. Hatcher was born at Cooperstown, Brown County, Illinois, 

 on October 11th, 1861. He was the son of John and Margaret C. 

 Hatcher. The family is Virginian in extraction. In his boyhood 

 his parents removed to Greene County, Iowa, where his father, 

 who with his mother survive him, engaged in agricultural pursuits 

 near tlie town of Cooper. He received his early education from 

 his father, who in the winter months combined the work of teaching 

 in the schools with labour upon his farm. He also attended the 

 2:)ublic schools of the neighbourhood. In 1880 he entered Grinnell 

 College, Iowa, where he remained for a short time, and then went 

 to Yale College, where he took the degree of Bachelor in Philosophy, 

 in July, 1884. "While a student at Yale his natural fondness for 

 scientific pursuits asserted itself strongly, and he attracted the 

 attention of the late Professor Othniel C. Marsh, the celebrated 

 Naturalist, at that time paleeontologist of the United States Geological 

 Survey. Professor Marsh, as soon as the young man had received 

 his diploma, commissioned him to undertake a palseontological 

 investigation in south - western Nebraska. Fi'om the summer of 

 1884 until the year 1893 he was continuously in the employment 

 of Professor Marsh. During these years he conducted explorations 

 over a wide area in the States of Nebraska, the Dakotas, Montana, Utah, 

 Wyoming, and Colorado. These expeditions to the western country, 

 which usually began early in the spring, continued until late in the 

 fall, or even into the early winter. He also collected in the winter 

 mouths and early spring in Maryland and North Carolina. His 

 success as a collector was phenomenal, and the scientific treasures 

 which he unearthed greatly enriched the collections of the United 

 States Geological Survey and of the Peabody Museum in New 

 Haven. It was upon the collections of vertebrate fossils made by 

 J. B. Hatcher that Professor Othniel C. Marsh based to a very 

 large extent many of his most important papers, and to Hatcher 

 more than to any other man is due the discovery and collection 

 of the Ceratopsia, perhaps the most striking of all the extinct 

 reptilia. Very little had been known about them, and before
