Topographical lists of this description are of necessity most unsatis- 
factory. The matter contained in them is never fully up to existing knowledge, 
and they are practically out of date before they come from the press. It is so 
with this list in many places. When half of it was in type an old collection 
of preserved plants with topographical notes, which has been called the 
“John Nicholson Herbarium,” and the ‘Simpson Collection,” came into 
the:possession of Mr. Arthur Smith, F.L.s., Curator of the County Museum. 
It was sent on to me for study. It dates from 1836, so these specimens—see 
the “Foreword "—supply many first records, that should take the place 
of those of the Revd. J. Dodsworth’s note book, and others of approximate 
dates. 
This is not the only difficulty. Botanical knowledge is ever expanding, 
and ready to be applied to collected facts. Dr. E. C. Moss’s paper on 
British Oaks in The Journal of Botany for this year, has thrown a flood of light 
on what was obscure specifically and also from the soil point of view. Both 
are specially interesting in such a flat county as this. After my record of the 
distribution of Quercus sessiliflora, Salisb., I added, ‘‘ Planted only?’’ From 
the evidence I possessed then that seemed the only legitimate suggestion.
