548 CAtfALOGOES. 



the original ms. catalogue is cited in the present work as " Hind 

 cat." The county of Middlesex is so small in its area, and so 

 humanly altered in its surface, that the temptation was con- 

 siderable to leave it out of notice in this work; and now I regret 

 that it was not originally combined with Hertford, instead of 

 being separately numbered ; — as Eutland with Leicester, as 

 Kinross with Fife, as Nairn with Easterness, etc. 



Mr. John Hogg. 



62, 65, 66. Alphabetical Catalogue, checked for plants ob- 

 served on either side of the Tees, from the coast upwards to 

 Blackwell. As this old catalogue does not distinguish the plants 

 by counties, it has not been quoted in the present work, although 

 used in former works by the same writer. Mr. Baker's ad- 

 mirable Botany of North Yorkshire and (jointly with Dr. Tate) the 

 New Flora of Northumberland and Durham were really made 

 the basis for vice-counties 62 64 65 66 67 68 ; although good 

 personal authorities have been cited from other sources. This 

 basis was the more convenient because the New Flora recognizes 

 my triple division of the two Tyne counties and arranges its 

 localities in accordance. 



Dr. George Johnston. 



68, 81. London Catalogue, edition second, checked for plants 

 found within three mUes of Berwick-on-Tweed ;" the space being 

 nearly all of it "in England" although partly "north of the 

 Tweed." As the catalogue will thus relate to portions, not only 

 of two counties, but even of two primary provinces, Tyne andEast 

 Lowlands, it becomes non-available in the present work. Actu- 

 ally, however. Dr. Johnston's very pleasing work, The Natural 

 History of the Eastern Borders, is the chief (unquoted) authority 

 for the county of Berwick, and for much in adjacent counties 

 also.
