Dear S I R, 
HE repeated favours You were so kind to 
bestow upon me, in the compass of a short 
acquaintance, and the zeal with which You promote 
the great cause of Natural History ; encouraged me 
to prefix Your Name to this Publication, and give 
me an opportunity, thus publicly, to acknowledge 
the assistance Your benevolent and generous friend- 
ship favoured me with. 
Nothing is left to me, but the simple mention of 
thanks; and my sincere wishes for Your health, 
happiness, and the enjoyment of every intellectual 
and moral blessing. I am, with the truest regard, 
Dear. ik, 
your most obliged, 
obedient, 
humble Servant,
