their description from the fourth volume of the^ original 
Cybele Britannica. ... In thus dividing the counties, any 
natural peculiarities were taken .... such as watersheds, 
roads, canals, rivers, etc.’ But in transcribing, he omitted 
the words ‘ in conformity with the watershed/ Whether 
accidental or intentional, this omission does not, I think, 
modify the boundary as defined in Cybele ; the explicit 
statement that he was repeating the description from Vol. IV., 
that natural features were used when possible, and the 
statement elsewhere that drainage lines offered facilities for 
easy determination in the field, all point to this conclusion, 
and a reasonable interpretation of this westward deflection 
is, that all the waters flowing into Dentdale are in North-West, 
and the southward flowing waters are in Mid-West, Yorkshire. 
Arnold Lees’ treatment of the matter in The Flora of West 
Yorkshire (page 103) was good — | An artificial line carried 
westwards from Newby Head Inn along the summit of 
drainage over Bleamoor to the top of Gragreth.’ A line 
along the summit of drainage should leave the political 
boundary at a. somewhat higher altitude, say the 1750 ft. 
contour line on Wald Fell, but the introduction of so well 
known a spot as Newby Head focuses attention on the general 
position of the boundary, and sweeps away the lax thinking 
that Ingleborough, Penyghent, or even Settle are in Watson’s 
North-West division. Messrs. A. Brown & Sons of Hull supply, 
in card form, a plan of Yorkshire showing the Watsonian 
divisions, with details of the boundaries. It should be noted 
that the Yorkshire Naturalists’ Union’s Dent meeting in May, 
1921, covered this boundary ’ most of the records (The Natural- 
ist, 1921, p. 273) belong to vice-county 65, but Greensett Moss 
and Force Gill drain southwards to the Greta ; the gullery on 
the former and the mosses in the latter belong to Mid-West, 
vice-county 64.

Guide to the University Botanic Garden, Cambridge, by 
H. Gilbert -Carter . The Cambridge Press, 1922, 3s. 6d. net. This 
volume, by the director of the garden, is an interesting and well- 
produced guide, and will be helpful, not only to the visitors to the garden, 
but also to the general reader. The sequence of families and genera is 
that of Engler’s ‘ Syllabus,’ and following the custom of zoologists, no 
capitals are used for trivial names. As the garden has long had a con- 
nection with oriental scholars, many eastern names of plants, also 
quotations illustrating the use of these names, are given. Many of 
these are translated, and will prove of much interest to the reader, but 
this method is very imperfectly carried out, and many unexplained 
names are introduced which will be quite meaningless to most users of the 
book. Prominent members of the University Staff have given assistance 
which is reflected to good effect in the volume where the more interesting 
biological features of the plants are described. There is a clear plan of 
the garden and twenty-four excellent illustrations from photographs.
