 accuracy of those results, together with my 

 professional character as an observer, will give

 the meteorological appearances of our very 

 irregular and unsettled climate. The nomencla- 

 ture of the clouds is Luke Howard's, by whom, 

 when a young observer, I was favoured with a 

 presentation copy of his valuable work on the 

 Climate of London.
