nicely, and will engrave the plates himself. As soon as the spring 

 approaches, he will visit the south of Ireland, and I have particularly- 

 urged him to seek for the Sticta macruphylla, which he will do if we 

 will send him the exact particulars of the station. ISTo one can do this 

 so well as yourself, and I have now to ask the favour of you to 

 communicate with him ; and I am sure, if you wish it, he will gather 

 the Sticta for you, and any other plant you may express a wish to have, 

 and that he may chance to fall in with. His address is ' W. H. 

 Harvey, Esq., Summerville, Limerick.' In the spring he wi]l make 

 Killarney his head quarters for some time." * * 



Mr. Wilson lost no time in communicating with Harvey, and sent 

 him full particulars of the habitat of the s ticta. In writing, he also 

 sent Harvey specimens of liypnum demissum and H. micans, with a 

 request that he would look out for these novelties also ; and on the 

 9th of Feb., Harvey replied, telling Wilson of his contemplated 

 journey, and also mentioning the fact of Koukeria loete-virens being 

 abundant at Turk Waterfall, and in fruit. 



Dr. Hooker happened to be preparing for the press his second 

 volume (the Cryptogamia) of the British FLoj-a, and on the 22nd March, 

 1832, he wrote to Wilson : I am working now at the lichens, and 

 have printed about one-third of that family. Your Sticta is, unques- 

 tionably, the most interesting British individual of the tribe. I shall 

 be greatly disappointed if, after the full statement of the locality you 

 have given to Mr. Harvey, he should fail to find it. With his corres- 

 pondence I did not doubt you would be pleased ; and he is as much 

 gratified in being put into correspondence vdth you." 



In April of that year Harvey went to Killarney. Though he was, 

 as we may believe, interested in the search for Sticta macrophylla, yet he 

 found opportunity for other work. He was at that time just tvv^enty 

 years old, and, as is the case with most young enthusiasts in Natural 

 History, his pursuits were somewhat varied. They embraced bird- 

 stuffing and shell collecting. Mosses and Jungermannia, flowering 

 plants and sea-weeds, were alike welcome to him. In this particular 

 journey he records the finding of Turbo politus, a rare shell, at Bantry, 

 and also a new species of Lymnea {^involida), very distinct from any 

 other, most like Lymnea glutiuosa, but differing abundantly. (Memoir, 

 p. 25.) But it is very surprising to find that the editor of the Memoir 

 makes no mention of the commission given to Harvey with regard to 

 Sticta ruacrophylla. At the end of April Hooker received a letter from 

 Harvey announcing his success ; thereupon Hooker wrote to Wilson : 

 "I have just heard from Harvey, and his letter is accompanied by 

 specimens of the Sticta. It was very soon in fruit."
