. 58.] TO CHARLES WRIGHT. 567 



letter, Dr. Gray felt as a great personal loss, as well 

 as a loss to science. He was a young man of much 

 promise, and he felt on leaving home that, in putting 

 him in charge of the herbarium and of the college 

 classes, he could not have made any arrangement more 

 promising and satisfactory. He had counted much on 

 his future help as assistant, and anticipated that he 

 would become a very valuable aid in carrying on his 

 work, for he had patience, conscientiousness, and 

 steady diligence. Mr. Mann's lungs were weak, and 

 his health required care, but nothing of immediate 

 danger was feared. But consumption developed rap- 

 idly, and he died after a few weeks' illness. 



Charles Wright was also working at Cambridge, 

 and took charge of the herbarium and garden during 

 Dr. Gray's absence.

I had yesterday at Marseilles a letter from Mrs. 

 Mann, conveying the sad intelligence of her son's 

 death. Very sad it is. ... 



My heart bleeds for poor Mrs. Mann, who was 

 wrapped up in Horace, and who feels it as the greatest 

 of disappointments. To me, also, it is a very great 

 disappointment of long-cherished hopes. 



I expect to find letters at Alexandria when we reach 

 there. We sail from Marseilles a week hence, going 

 meanwhile to see some of this famous shore further
