various nationalities, whose pursuits were akin to his own. Intel- 

 lectual sympathy and co-operation led to strong friendships founded 

 securely upon common tastes and mutual services. All these are 

 elements of happiness, — love of nature, acquaintance with the 

 wide earth, congenial intercourse with superior minds, and abiding 

 friendships. 



Although Dr. Gray had no children, his domestic experience was 

 one of rare felicity. His life illustrated a remark of his friend Dar- 

 win, that with natural history and the domestic affections a man can 

 be perfectly happy. His way of living was that most agreeable to 

 a philosopher ; for it was independent, comfortable, and free alike 

 from the restrictions of poverty and the incumbrances of luxury. 

 With simplicity and regularity of life went health and a remarkable 

 capacity for labor. 



All appropriate honors came in due course to Dr. Gray from acade- 

 mies, scientific associations, and universities, at home and abroad. 

 The stream began to flow as early as 1844, and continued to the 

 end of his life. With these honors came the respect and affection 

 of hundreds of persons who were devoted to the pursuit in which 

 he was a leader. His reputation was larger than that of a specialist ; 

 he was recognized as a clear thinker on philosophical and religious 

 themes, a just and sagacious critic, and a skilful and vigorous writer. 

 It is the greatest of human rewards to be thus enfolded, as years ad- 

 vance, in an atmosphere of honor, gratitude, and love. 



Finally, Dr. Gray enjoyed the conscious satisfaction of having ren- 

 dered during his long and industrious life a great and lasting service 

 to his kind. For many years past he could not but know that he had 

 made the largest and most durable contribution to American botanical 

 science which had ever been made, and that he had done more than 

 any other man to diffuse among his countrymen a knowledge of botany 

 and a love for it. He knew, moreover, that by his own work, and 

 by the interest which his labors inspired in others, he had placed 

 on a firm foundation the botanical department of the University which 

 he served for forty-six years, and that the collections he had created 

 there would have for generations a great historical importance. To 

 have rendered such services was solid foundation indeed for heartfelt 

 content.
