Ivi PEOCEEDINGS OF THE GEOLOGICAL SOCIETY. [May 1 899, 



levied from among several generations of assistant co-workers. 

 The magnitude of the private and public collections accumulated at 

 Albany, the large sums spent for their investigation, and the 

 elaborate publication of results, together with the amount and 

 variety of the investigations carried on, attracted the rising and 

 ambitious palaeontologists of the IJnited States to ji^lban}^ for many 

 years. This enabled the State Geologist to equip himself with some 

 of the best talent in the country, and in a considerable degree 

 determined the quantity and character of the output of his depart- 

 ment .... As a lobbyist among over sixty annual legislatures he 

 held an unique position in the State. In his successful adjustments 

 to the kaleidoscopic and bewildering political complexion of this 

 long period is shown his wealth of resource and adaptability. 

 In his managerial skill and tireless energy he was alone and 

 without a peer.' 



[Since this notice was written a long account of ' The Life & 

 Work of James Hall,' by H. C. Hovey, has appeared,^ with Lists 

 of his Titles and Memberships and of his Published "Works, which 

 number 42 books and 260 papers, ranging in date from 1836 to 

 two * in the press.' Of course, many of these were joint work.] 



Jules Maecoit was born at Salins, in the French Jura, on April 

 20th, 1824, and worked with J. Thurmann on the geology of 

 the Jura Mountains. He acted as travelling geologist for the 

 Jardin des Plantes, of Paris, visiting North America in 1847, and 

 accompanying Agassiz to the Lake Superior district in the following 

 year. Later on he studied the geology of New Jersey, of Pennsyl- 

 vania, and of Virginia. He made a short visit to Europe in 1850, 

 but then returned to America, and published his geological map of 

 the United States and the British possessions in North America. 



He entered the geological service of the United States in 1853, 

 but was forced by ill health to return to Europe in 1855, from 

 which year to 1859 he held a Professorship in the Polytechnic 

 School at Zurich. In 1861 he again went to the United States, 

 and helped Agassiz in founding the Museum of Comparative Zoology, 

 taking charge of the palseontological division. In 1875 he re-entered 

 the national service for a time. 



Among his many publications should be noticed a geological 

 map of the world. 



Of late years, his papers were mostly of a controversial nature ;
