There were moments, no doubt, when this asserted itself in a some- 

 what rigid way. No man ever believed more firmly iu tlie principles 

 which his faith and his experience had combined to teach him ; and, 

 as the years passed, these principles had in them enough of the old 

 school sometimes to formulate themselves in a manner which came very 

 near to prejudice. Then appeared that firmness of feature from which 

 every trace of laughter or mirth, of everything but deep, earnest convic- 

 tion, had all faded. Then, instead of buoyant, cheery words came words 

 of marked, cool, and sometimes sharp decision. And yet even iu mo- 

 ments like these, when to those who did not wholly share his opinions 

 and feelings his motives seemed least liberal, there was always an under- 

 lying, evident truth and simplicity of heart which brought, even with 

 a sense of unmerited reproof, a feeling of tenderness for him. Like all 

 of us, he was human, with foibles and with fallings which be would 

 have been the last to dissemble or to deny. He had the limits and the 

 prejudices of his race and of his time; but more surely still he possessed 

 the virtues of that vanishing old New England whose tiaditions he so 

 loyally preserved to the end. 



"Integer vita3, sceleiisque purus," wrote the Roman poet; and for 

 centuries the words have been held to typify such a character as so lately 

 has passed from among ourselves. And there is another saying, a sacred 

 one which he would have cherished most, with little thought of how 

 truly we who are left can repeat it of him : " Blessed are the pure in 

 heart ; for they shall see God."

JULES MARCOU. 



Jules Marcou, the subject of this notice, was born at Salins, 

 France, April 20, 1824. He was educated at the College of Salins 

 and the Lyceum of Besangon, and entered the College of St. Louis at 

 Paris in October, 1842, but retired on account of ill health occasioned 

 by too great application to mathematical studies in the spring of 1844,

 Annales de Mathematiques," Terquem et G^rono. Paris, 1843-44. 



By the advice of his family physician. Dr. Germain, he made long 

 excursions on foot into the country around his native city, and iu order 

 to give objective interest to these walks collected and studied plants
