Letter XVII
To The Honourable Daines Barrington
Ringmer, near Lewes, Dec. 9, 1773.
Dear Sir,
I received your last favour just as I was setting out for this place; and am pleased to find that my monography met with your approbation. My remarks are the result of many years' observation; and are, I trust, true on the whole: though I do not pretend to say that they are perfectly void of mistake, or that a more nice observer ought not make many additions, since subjects of this kind are inexhaustible.
If you think my letter worthy the notice of your respectable society, you are at liberty to lay it before them; and they win consider it, I hope, as it was intended, as an humble attempt to promote a more minute inquiry into natural history; into the life and conversation of animals. Perhaps hereafter I may be induced to take the house- swallow under consideration, and from that proceed to the rest of the British hirundines.
