I Acquainted the Publick at the Conclufion of my fecond Part of this Work, that I had 
no Thoughts at that Time of continuing my Hijlory of Birds •, (for then indeed I had not 
Matter fufficient to proceed upon-,) but fince then I have been fo fortunate, by the Af- 
fiftance of my Friends, as to colled a proper Number of new Subjects, fo as to add a third 
and fourth Part to this Work : which two Parts will contain the fame Number of Plates 
that are given in the firft and fecond Parts compofing the firft Volume, Thofe Gentle¬ 
men who take the two laft Parts, may very conveniently bind them up together, as the two 
Parts will make up a Volume only of a moderate Thicknefs. This third Part confifls 
wholly of Birds, excepting a little Addition ifPfBtne of the Plates by way of Decoration. 
The fourth Part will be publifh’d in twelve Months at molt from the Delivery of the third 
Parr, the Plates being all finifhed, and fome few'of them already Printed off and Colour’d 
as Specimens, which may be feen at my Houfe; by any one that defires it. The Manufcript 
Copy, defcribing the Figures of the laft Part, is allb prepared and now ready for the Prefs. 
The laft Part will contain thirty-feven Plates of Birds, and fixteen Plates containing fome other 
curious and undefcribed Animals, fuch as Quadrupeds, (both Land and Amphibious) Serpents, 
Reptiles, Fifhes and Infects. 
I lhall defer giving the Names of my additional Subfcribers till the Publication of the fourth 
and laft Part of this Natural Hijlory : In the mean Time I hope fuch Gentlemen and La¬ 
dies, as have encouraged this Work, through the Hands of fome of my Friends that are 
Bookfellers, as well as fuch of my good Friends who have taken the Books dire&Iy of 
me, will be pleafed to honour me with their Names, by fending them either to their Book¬ 
fellers or to me, and they lhall be inferted. 
As the fourth Part will complete tw 7 o Volumes, containing in all two hundred and ten 
Plates of the Natural Hiftory , befides two other Plates ; and l finding myfelf deftitute of Ma¬ 
terials to proceed any confiderable Length farther in this Work, 1 lhall abfolutely ftop and 
finifii here. Declining Age, its neceffary Confequences, and growing Incapacities, are alfo 
good Reafons for me to difcontinue proceeding in a Work, that by lying too heavy on the 
Brain, may only ferve to ltupify myfelf, without being of any Benefit or Advantage to the 
World. As I have now fimlhed this Work, it is my Intention to devote the Remainder of 
my Days to Quietnefs and Repofe, much Attention not v/ell agreeing with People in their, 
later Years. 
In Perufing thefe Defcriptions, without having the Figures prefent, I muft confels fome 
Parts of them feemed to me a little obfcure -, but on a fecond Reading, with the colour’d 
Figures before me, the Defcriptions and Figures ferved to explain each other fo well, that I 
trull moll of my Readers will readily comprehend the Senfe and Meaning of them, agreeable to 
my Conceptions or Ideas when i wrote thefe Mieets. I have marked the firft Plate of the firft 
Part with N° 1 . and have gone on numerically from thence to the End of the laft Part, 
which I think will breed lels Confufion than il I had made the firft Plate of each Part to 
begin with N° i. A Catalogue of the Names of the Animals contained in the third and fourth. 
Parts will be given at tire End of the fourth Part when it is publifhed.
