time to Mosses. He studied medicine but never graduated; he was Profes- 

 sor and Examiner in the Philadelphia College of Pharmacy many years; 

 Secretary of the Pennsylvania Horticultural Society, and after the death of 

 Dr. Darlington took his place as Professor of Botany. He was also Treas- 

 urer of the American Pomological Society till his death and was indefatiga- 

 ble in its interests, editing and indexing its biennial reports, etc It was in 

 connection with Dr. Darlington's editing of the Bartram correspondence 

 that my father made the acquaintance of his future wife, Miss Isabelle 

 Batchelder. She was a friend of Dr. Asa Gray's and much interested in 

 Botany, and gave valuable suggestions regarding the illustrations to the 

 Bartram Letters. They were married in old Christ-Church, Cambridge, 

 Mass., in December, 1851. They lived a few months in Philadelphia, then 

 settled at Burlington, New Jersey, where I was born: the following winter 

 they returned to Philadelphia, and here my two brothers and sister were 

 born. Now came the time when my father began to give the fruit of his 

 labor to the public. In 1853 he prepared the list of Anophytes, e., Mosses 

 and Liverworts for Dr. Darlington's third edition of Flora Cestrica. A lit- 

 tle later the Flora of Delaware County to Dr. George Smith's History of that 

 county. 



Under date Nov. 12, 1855, Dr. Asa Gray writes: "The first sheets of 

 the revised edition of the Manual is now in the printer's hands — and I am 

 going on with it pretty fast. After a while SuUivant is to revise the mosses 

 and hepaticse, adding all the species he knows in Atlantic States, e., east 

 of the Mississippi. If you do not like to furnish him a list of the species you 

 have detected, I think it would be well (and the only way to secure the 

 priority of your discoveries) for you to publish beforehand a list of the 

 mosses you know, or of those you have detected which are not in the 

 Manual. Only you should do it soon. These people that wait for perfec- 

 tio7i before they give their knowledge to the world, I notice generally die 

 before they reach the acme. And I should think it hard if you know of 

 mosses in New England which we do not and you let a new edition of my 

 Manual come out, and be stereotyped while you confine that knowledge to 

 your own bosom. As to those thought to be new, why not decide and bring 

 them out or keep those for further investigation." 



. A hall room on the third floor, in the Thirteenth and Locust street 

 house, was given up to mosses. The walls were entirely lined with high 

 wooden cases, grained to imitate oak, whose fronts let down and showed 

 innumerable pasteboard boxes filled with mosses from all lands. Above 

 them hung engravings of botanists. A delightful mossy smell pervaded the 

 room, and in the window stood a little table on which were the microscope 

 and many watch crystals with moss floating in water. To this den I used to 

 come with specimens or letters as they arrived, feeling sure of a hearty wel- 

 come, especially if I brought a letter postmarked " Columbus, O," addressed 

 in the fine script of Mr. Leo Lesquereux, LeCru as we always called him. 

 My father began sending him mosses soon after he came to this country in 

 1848, and a constant correspondence was kept up between them until my
