myfelf obliged publickly to acknowledge. When I had prattifed a little while, I refolved 
to do fuch new and uncommon Birds, as Thad in my Poffefion, fince I faved Expences 
and only employed my Time. 
In etching Plates which are - afterwards to be coloured, I have diftovered, that they 
feould be done in a manner different Srom fuch things that are to continue Blach and 
White; therefore I am willing to publifh fuch Remarks on that Head, as may perbaps 
be of ufe to others that may hereafter publifh any thing of that kind. He who would 
make a Print after any coloured Drawing, should make his Lights much lighter than 
_ they are in the Drawing, and the Shadows. rather darker, which will indeed give your 
Print a fomewhat fhocking Degree of Light and Shadow; but when you confider that 
by colouring, your Lights will become darker, and your very black Shadows, by being 
wafbed with Colours, which generally are lighter than Black, will become Something 
lighter ; in Prints for colouring, it will be convenient to leave pretty broad clean white 
Places that area little dark in your colour'd Drawing: For Example, if a Part in your 
Drawing be of Blue or Red, or any fine Colour pretty deep; if you make your Print of 
Jo deep a Shade in thofe Parts, the Blacknefs will caft through the tranfparent Colours 
which you muft ufe in wafhing Prints, and render them dead and dirty ; and if you lay 
on too great a Body of Colour, tt will darken your Figure too much in the Lights, and 
make tt flat and heavy. On the contrary, if you leave Lights as broad and as clean as the 
thing will permit, your Calours 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 fudg- 
ment, it will lfe its too great Proportion of Light and Shadow, and become foft and 
agreeable, and decetve tolerable “fudges Jo far as to pafs for a Water-colour'd Draw- 
ing. Prints that are not worked with a dire Defign for colouring, cannot fo eafily be 
brought to that Beauty ; they muft 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 live, 1 oft they 
Should be afterwards colour'd by unskilful People, which might be a Blemifh to the Work, 
by being feen and taken for my Colourings.. Copy carefully and exactly colour’d from 
the original Drawings, will be depofited in the Library of the College of Phy fcians,
