The ' Flora of the East Riding- of Yorkshire,' in light g-reen 

 apparel, with sug-g-estions of aquatic plants, and with head and 

 tail piece sketches of local places, contrasts strong-ly with the 

 'Flora of West Yorkshire,' thick, solid-looking-, but 'full ot 

 strange oaths ' ; while both look much more impressive than the 

 paper-covered numbers of the unfinished 'North Yorkshire.' Yet 

 the plain covers of the last enclose a study on plant-distribution 

 which has elevated it frorn a list of species and localities interest- 

 ing only to the local botanist, into a standard work on plant- 

 distribution, of interest all the world over. Since the earlier 

 part of 'North Yorkshire' was penned the study oi plant- 

 distribution has advanced much, and the author of a Flora has 

 to-day many demands to satisfy. The day is past when a 

 statistical list of natives, casuals, etc., with their localities, can 

 be accepted as a Flora ; although in the case of Algae, Fungi, 

 and Mosses, groups imperfectly investigated as yet, we must 

 content ourselves for a time with lists and notes on localities. 

 It is now expected that the author of a Flora should not merely 

 give statistics, but should interpret them and attempt to advance 

 some aspect of plant-life. In ' North Yorkshire' the account of 

 the geology becomes, in the chapter on lithology, the key to the 

 solution of problems in an area with a complex but interesting 

 flora and geology. The account of the clirnatology is correlated 

 with its results on plant-life. The descriptions of the river- 

 basins are pictures of the vegetation to w^iich Yorkshireman or 

 stranger can turn again and again and see new points of 

 beauty ; it lacks completeness only because the pictures are 

 river-valleys, and the moorlands between are left in the back- 

 ground. The author of ' The Flora of West Yorkshire ' has 

 appreciated Mr. Baker's lead in following up Thurmann's 

 principles. B}' using Davis and Lees' ' West Yorkshire ' one 

 gets again a series oi pictures of the vegetation, whose greatest
