collected by G. H. K. Thwaites, Esq.' In 1871 appeared 'The 

 Lichen Flora of Great Britain,' which was reviewed somewhat 

 severely in this Journal*; the second edition appeared in 1872, 

 and the third in 1879. He contributed a series of papers to 

 * Grevillea,' extending from 1872 to 1876, entitled * Lichenological 

 Memorabilia ' ; a paper on * Stigmatidium dendriticum ' to this 

 Journal for 1875 ; and read two papers before the Linnean Society 

 on ' New British Lichens ' in 1876, and another on ' New L:ish 

 Lichens ' in 1879. 



After completing his third edition of the * Lichen Flora of Great 

 Britain,' he abandoned the study, finding it too much for his eye- 

 sight, and presented the whole of his valuable and extensive 

 collection of Lichens, enriched by many foreign published fasciculi, 

 to the Kew Herbarium, besides giving a great number of duplicates 

 to the Shrewsbury Museum. Henceforth he devoted his attention 

 to archaeology, which, from early days, had shared a large portion 

 of his time, and having taken an active part in establishing the 

 Shropshire Archaeological and Natural History Society, he became 

 the honorary editor of its Transactions, to which he contributed 

 many valuable papers. He was a Fellow of the Linnean Society, 

 but retired in 1887, and of the Botanical Society of Edinburgh, 

 from which he retired about the same time ; as well as an honorary 

 member of several Natural History Societies. His name is asso- 

 ciated with the following plants: — Opegrapha Leightonii Cromb., 

 Lecidea Leightoniana Larb., Agaricus Leightonii Berk., Sphmia 

 Leightonii B. & Br., and Calloria Leightonii Phil. 



In disposition Mr. Leighton was generous and warm-hearted, 

 an agreeable and stedfast friend, and at all times ready to assist 

 those engaged in his favourite pursuits. He was twice married, 

 and bears a son and two daughters by the first wife, and a son by 

 the second, who survives him. He was buried in the General 

 Cemetery, Shrewsbury.
