Ixiv PEOCEEDINQS OF THE 



sonian Institution at "Washington and the Harvard University at 

 Cambridge, U.S., to visit the United States, and under their 

 auspices to deliver courses of botanical lectures at these and 

 kindred institutions, and also to undertake the arrangement and 

 classification of a large collection of plants in possession of the 

 former. He complied with the proposal, and having performed 

 these services, and visited Canada and the southern shores of Flo- 

 rida in pursuit of his favourite Algse, he returned home in the 

 year 1850, after an absence of about nine months, to resume his 

 duties in the University of Dublin. 



" His great zeal and enthusiasm inspiring him with a wish for 

 a wider field of labour in pursuit of science, he applied to the 

 University for liberty to make a voyage round the globe, chiefly 

 with the object of making himself acquainted with marine plants 

 in their native habitats, and to collect objects of natural history 

 for the herbarium and museum of Trinity College. His wish was 

 granted, and under the auspices of the University he started by 

 the Indian mail in the year 1853 for Ceylon and Australia. He 

 visited the east, south, and west coasts of Australia and Yan Die- 

 men's Land ; and on his return from the latter to Sydney, find- 

 ing that some Methodist missionaries were about to visit in the 

 * John "Wesley,' a small vessel belonging to the mission, the various 

 islands in the Southern Pacific, touching at New Zealand, he 

 solicited liberty to accompany them, which was kindly granted, 

 and in June 1855 they sailed for Auckland, the Feejee and Friendly 

 Islands. 



" Prom the Peejee Islands he returned to Sydney, whence he 

 made a voyage to Valparaiso, where his health again gave way ; 

 thence he passed north, and crossed the Isthmus of Panama, re- 

 turning by the West India Mail to England in October 1856, after 

 having expended three years in this scientific voyage round the 

 world. 



" On his return to Dublin, in 1856, the Professorship of Botany 

 became vacant through the appointment of his friend Dr. Allman 

 to the chair of Zoology in the University of Edinburgh, and the 

 post was conferred upon him and retained till his death. 



" The following is a list of Dr. Harvey's principal works. It 

 does not include the numerous papers communicated to various 

 Botanical periodicals, and especially to ' Hooker's Journal of 

 Botany,' Eoyal Irish Academy, Dublin Natural History Society, 

 and sundry systematic works of his botanical correspondents and 

 friends.
