1 72 1, edited Ray's synopsis 3 ed. 1724, Hortus Elthaniensis 
1732, Historia Muscorum 1741. {Biographical Index of 
British and Irish botanists by Britten and Boulger, 
The figures of the mosses given in His. Muse, of Dillenius 
are all drawn the natural size of the plants, the engravings 
are so good that many of the larger mosses can be recognised. 
Dr. R. Richardson, of North Bierly, near Bradford, was a 
correspondent of Dillenius, and some localities for mosses 
are given for the West Riding in the Hist. Muse. ; none, 
however, are recorded for North Yorkshire. 
Four Fasciculi of Cryptogamic plants were published in 
London by James Dickson. 
Fasc. 1, published in 1785 contains the description of 
14 Mosses and 6 Hepaticae. On Tab. 1 are drawings ot 
some of the mosses and i Hepatic, all of the natural size 
of the plants. Fasc. 2, published 1790 contains 37 Mosses 
and 4 Hepatics. In Tab. 4 of this Fasc. several figures are 
given with magnified drawings of dissections of the leaves of 
both mosses and Hepatics, which are probably the first 
magnified figures of these minute plants engraved in 
England. Fasc. 3, published 1793 contains 37 mosses and 
4 Hepatics. Fasc. 4, published 1801 contains 57 mosses 
and 4 Hepatics. In this fasciculus there is a small moss 
named Brywn pancijolium^ which is recorded from Yorkshire, 
.gathered near Wetherby. A figure of the moss is given on 
Tab. II. This moss has not been met with since near 
Wetherby. It is found in Kent. In the spring of 1894 
Mr. J. Marshall met with it abundantly near Market 
Weighton, in the East Riding of Yorkshire, growing on 
loose blocks of chalk rock, at the base of a railway 
embankment. It. is a minute moss, belonging to the 
family Dicranaceae, now named Seligeria paucifolia [Dicks.) 
CarrutherSy and is a most interesting re-discovery of a 
Yorkshire moss, although in another part of the county.
