all of which are new to Britain, and 20 of them were mosse 
found in North Yorkshire by Spruce. 
A more recent work, "The Students Handbook of British 
Mosses," by H. N. Dixon, M.A.F.L.S., with illustrations 
and keys to the genera and species, by H. C. Jameson, M.A., 
was issued in 1896. A second edition was published in 1904. 
The nomenclature in this book follows mostly that adopted 
in Wilson's ''^ Bryologia Britannica.'' In the second edition 
there is revision of some of the g^enera such as Sphag-num, 
Weissia, Pottia, and the Harpidioid Hypna. 
The more natural arrangement adopted by Braithwaite is 
not used, although many of Braithwaite's new generic names 
are given as synonyms. 
The book is a handy working book. 
Robert Teesdale, who was some time principal gardener 
at Castle Howard, drew up his " Plantse Eboracenses," 
which was printed in the first volume of the " Linnean Tran- 
sactions." This was a list of the native plants growing 
chiefly around Castle Howard. A supplement to this was 
printed in the second volume of these Transactions (1798) 
which contained a copious list of flowering plants, as well as 
a list of 71 Urn Mosses and 23 Hepaticae for the whole 
county. Both lists are carefully drawn up, and are still 
referred to by writers on Botanical Geography, and the list 
of mosses is one of the earliest for Yorkshire. 
A supplement of Baines' " Flora of Yorkshire " was 
published in 1854, the first part, giving a list of the flowering 
plants and ferns, by John Gilbert Baker. The second part 
contained the mosses of the county, by John Nowell, of 
Todmorden. This enumerates 329 Urn Mosses then known 
in the county. The contributors to the list were R. Spruce, 
W. Mudd, W. Brunton, J. G. Baker, Dr. J. B. Wood, J. H. 
Davies, S. Gibson, Rev. J. Dalton, S. Hailstone, H. Ibbotson. 
The first edition of " North Yorkshire," by John Gilbert 
Baker, was published in 1863. It contained a very full list
