thus brought upon him did not prevent his pushing on vigorously 

 with the now large arrears of phycological work. His first 

 action was to finish and publish the third and last section of the 

 Nereis B or eali- Americana and then bring to a conclusion his 

 enumeration of the seaweed flora of North America. This was 

 accomplished in 1858, and in the same year he began the publi- 

 cation of the results of his work in Australia. The Phycologia 

 Australica, which was issued in parts during the ensuing five 

 years, ran to five volumes, each containing sixty coloured plates, 

 and descriptions of all the species known from Australasian 

 waters. In the year following the launching of this work, he 

 commenced the publication of two important treatises on the 

 phanerogamic flora of South Africa. In the first of these, the 

 well-known Flora Capensis, he had the co-operation of Dr O. W. 

 Sonder of Hamburg. This extensive work he did not live to 

 complete ; the third volume, which ran as far as the end of the 

 Campanulaceae, being published the year before his death. The 

 other work was his Thesaurus Capensis, a series of plates of rare 

 or interesting South African plants, designed to supplement and 

 illustrate the unillustrated Flora ; of this he lived to issue only 

 two volumes, each containing one hundred plates. 



Harvey's home life, which for several years had been very 

 lonely, was transformed in 1861, when, at the age of fifty, he 

 was married to Miss Phelps of Limerick, whom he had long 

 known. But almost immediately afterwards the shadow of death 

 appeared, haemorrhage from the lungs warning him that his 

 newly found happiness might not endure. After a summer 

 spent at his favourite Miltown Malbay, on the wild coast of 

 Clare, he was able to resume his college duties and his work on 

 Flora Capensis. Although he never fully recovered his health, 

 he laboured diligently at the works he had in hand. He had a 

 noble example of continued devotion to science in his old friend 

 Sir William Hooker, whom he again visited, on returning from 

 a tour on the Continent, in the autumn of 1863, to find him, in 

 his seventy-ninth year, finishing off the last volume of his 

 Species Filicum, and " already beginning to nibble at another 

 book." This was a further work on ferns, the Synopsis Filicum, 

 on which Hooker was busily engaged until within a few days
