PREFACE, 
Lights^ and make it flat and heavy. On the contrary^ if you leave 
Lights as broad and as clean as the thing will permity your Colours laid 
on fuch light Parts will appear with more Luftre than with black Strokes 
under them ; and when the Print is wafhed with a little yudgme?tty it 
will lofe its too great Proportion of Light and ShadoWy and become foft 
and agreeablcy and deceive tolerable Judges fo far as to pafs for a 
JV ater-colour d Drawing. Prints that are not worked with a direSi 
Deflgn for colouringy cannot fo eaflly be brought to that Beauty ; they 
mufl be labour d and painted with body Colours to make them look 
tolerably. 
I do not purpofe to part with any of the Prints uncolour d while I 
livey lefl they Jhould be afterwards colour d by unskilful Peopky which 
might be a Blemijh to the Worky by being feen and taken for my Colour • 
ings. A Copy carefully and exaSily colour d from the original DrawingSy 
will be depofeted in the Library of the College of Phyficians, ^London, 
which may ferve as a Standard to refer to and compare withy to try the 
L*ruth of the Colouringy in cafe the Plates fhould outlive mcy and any 
jhould queflion the Authority of the Colouring. I had thought when 
^ hV irk to have graved One hundred Plates of new 
Birds y but found I was under a necefflty to leave ojf at Fifty y not being 
able to procure any more but fuch as have been defcribed by many others. 
Seeing it is now known that I have do?u thefcy and am willing to go ony 
if I can procure any more of curious GentlemeUy I hope fuch Gentlemen 
of T*afle this wayy who have at any time Birds new and curiousy will 
pleafe to give me noticcy that I may wait on them to take DrawingSy 
which Favours I fhall always gratefully acknowledge. It is now my 
duty^ to acknowledgcy with all pofflble Gratitudcy the Afftflance 1 have 
received from ma?ty curious Gentlemeny and give my publick Thanks in 
general for the 7natiy and great Favours I have received from thefe fny 
honourable and worthy Patrons and Friettdsy who from time to tme have 
given me free Acccfs to their HoufeSy and intrufled me in their Cabinets 
of Curiofltiesy and have oftentimes lent me very valuable and curious 
Things in order to forward me in my Purfuits : Yet in the courfe of thefe 
Defcriptmis 1 for my own Reputation ( in order to prove the Being of the 
Birds here reprefe?ited ) have tnentioned the Names in particular of my 
Patronsy
