OBITUARY NOTICES. 



Professor George H. Cook died suddenly of heart failure on September 

 22, 1889. He was born at Hanover, New Jersey, on January 5th, 1818. 

 In 1836 he became a civil engineer, and his first work was in laying out 

 the line for the Morris and Essex railroad. He also surveyed the line for 

 the Catskill and Canajoharie railroad. He was not, however, satisfied with 

 his attainments, and entered the Troy Polytechnic Institute in 1838, grad-

 1842 he was made " senior professor," an office equivalent to that of presi-

 philosophy in the Albany Academy. In 1851 he became principal of the 

 academy, and held the office two years, until his election to the chair of 

 chemistry and natural philosophy in Rutgers College. The next year he 

 was made assistant geologist of New Jersey, which position he held for three 

 years. The office of state geologist had been allowed to lapse for several 

 years, but a paper read by Professor Cook before the legislature, in 1864, 

 led to its reorganization and to his appointment as its head.

 under his supervision have been adjudged to be among the best published 

 by the different states. The last of the series was recently issued, and
