account of the original hints there given, it will not be deemed 
the leafl ufeful and important part of this treatife. 
The Duke of Portland, after all his other indulgences, was 
pleafed to give me free accefs to his Grace’s noble library at 
this place, which has enabled me to add many important ob- 
fervations in the notes^ which cannot fail of being acceptable 
to the reader. The names of the authors confulted will appear 
in the refpecflive notes. 
Here now, that I am drawing my preface to a conclufion, I 
muft intreat the reader to permit me to make my acknow- 
ledgments, that I may not appear ungrateful to fome of my 
living friends. — My warmed thanks are due to my much- 
efteemed and truly-learned friend the Rev. Samuel Pegge, of 
Whittington, Derbylhire, for his excellent 7 iQte on the large 
bunch of grapes produced at Welbeck in the year 1781, inferted 
in p. 41 — alfo for his curious and important note in p. 186 — 
and likewife for his further friendly afiftance. 
I feel mylelf under fingular obligations to my worthy and 
learned friend the Rev. Mr. Michell, for his obliging commu- 
nication of a new and eligible method of railing Vine-plants ; 
and alfo for his important note on this fubjedt, inferted p. 53, 
William Hanbury, Efq; has my warmed thanks for having 
obligingly favoured me with an account of the furprifing pro- 
grefs
