attaining the highest eminence. His tastes were varied, leading 

 him into natural science, language, art, and music, in all of which he 

 accomplished original work of the highest grade. He loved study, and 

 always entered with his whole soul into the investigation of whatever 

 subject interested him. He was filled with a noble ambition and ac- 

 tuated by the purest purposes, and thus ever sought to advance the 

 interests of science without thought of personal gain. In his short 

 life he accomplished much, but so great was his confidence in the fu- 

 ture, that he withheld the publication of many of his discoveries 

 until they should be further developed and perfected, little expecting 

 so sudden a termination of his work. 



Although linguistic studies, as well as art and music, were to him 

 favorite subjects of investigation, they were generally treated from a 

 scientific stand-point, and were made subordinate to the more special 

 field of inquiry, geology, to which he early became enthusiastically 

 devoted. With an ever increasing love for scientific research, which 

 finally came to absorb his whole attention, he died a martyr to science. 

 Eminently successful as a teacher, his students shared his deep en- 

 thusiasm, and his influence upon science will long be felt through the 

 labors of those who enjoyed the advantages of his careful training. 



Prof. Hartt was the oldest son of the late Jarvis William and Pru- 

 dence (Brown) Hartt, and was born at Fredericton, New Bruns- 

 wick, August 23, 1840; he died at Rio de Janeiro, March 18, 1878. 

 His last illness was of scarcely more than forty-eight hours dura- 

 tion ; his death was sudden, and, until near the end, entirely un- 

 looked for by even those who were watching over him. Pie was 

 attacked with a light fever on a Friday night, and this continued 

 without dangerous symptoms until nearly midnight Sunday, when he 

 became delirious. In this state he remained until three in the morn- 

 ing, when he passed away. The unexpectedly fatal termination of his 

 illness can be accounted for, only on the supposition that his system 

 had become greatly enfeebled by his constant, hard work and anxiety 

 during the long, tropical summer. He had been accustomed to leave 

 Rio in the hot season,- but this year circumstances prevented his 

 doing so. 



Hartt's early education was carried on under the direct supervision 

 of his father, who, for a long time, was prominently identified with the 

 educational interests of Nova Scotia and New Brunswick. He stud- 

 ied at Horton Academy in Wolfville, N. S., and afterwards at Aca- 

 dia College, where his father was at the time a professor. In 1860
