and freely helped other botanists with his knowledge ; also an 
accurate knowledge of the British Lichens, adding several new 
species to our Flora, corresponding with Leighton, Mudd, and 
other contemporary authorities. His knowledge of the British 
Mosses made him a no mean, though friendly, rival of Wilson, 
Spruce, and other leading authorities. He contributed several 
papers to the Phytologist, Proceedings of the Botanical Society of 
Edinburgh , and other scientific journals, his most important papers 
being on the British Orthotrica. 
It will, however, he by his devotion to the study of the Hepaticse 
that his name will especially be remembered. 
He practised first at Radcliffe, near Manchester ; then in succes- 
sion at Lincoln, Yeadon, Southport, and Eccles. 
In 1861 he visited the south of Ireland, his chief object being, 
as he says (after the renovation of his health), the collection and 
study of the Hepaticse. The results of this visit was the appear- 
ance of his interesting “ Gleanings among the Irish Cryptogams,” 
published in the Trans. Bot . Soc. Eclin. in 1863 ; an extensive list 
of lichens, mosses, and hepaticse, with valuable notes on many 
species, especially of the latter order. It is illustrated by two 
beautiful plates, which indicate the skill he had attained in the art 
of delineating cryptogamic plants. Another result of this visit 
to Ireland was the rich contribution he made to Rabenhorst’s 
Bryotheca europeoe , and Gottsche and Rabenliorst’s Hepaticce 
europeoe, one part of the latter being almost composed of the 
doctor’s collecting. 
In 1862 appeared Miall and Carrington’s Flora of the West 
Riding , for which he compiled the list of cryptogams. 
About this time he began to prepare a work on the British 
Hepaticse, corresponding with all collectors and those interested in 
this group : De Notaris, Gottsche, and Lindberg on the Continent; 
Wilson, Hooker, Spruce, and others here. 
In 1874 appeared the first part of what promised to be the most 
important work since the publication of Hooker’s magnificent British 
Jungermannioe , in 1816. Three further parts were issued in 1875 
and 1876. The fourth had an ominous note appended, which 
stated that in consequence of the indisposition of the author the 
letterpress was some pages short. For some time he continued in
