I Muft not forget to acknowledge the many kind Offers of Service which have' 
been made me by my Curious and Learned Friends (fome of which I have ac- 
cepted) towards compleating this Work, by perufing the Manufcript Copies, and 
giving me their Advice, which I have found to be of great Advantage,, tho* none of 
them have thought proper to make any material Alterations in the defcrlptive Parts 
ot the Work. The mod; confiderable Help I have received w’^^as from Dr. Mortimer^ 
Secretary of the R, (S', whom I confulted in Relation to the proper Claffical Latin 
Names, as they are placed together with the EngliJIo Names I have given in the 
Catalogues at the Ends of the fecond and fourth Parts of the Book : There was a 
more than ordinary Difficulty in this, as the Subjeds confided mofkly of Things, which 
were never before defcribed, and confequently no Claffical Latin Names could be 
found to anfwer many of them j in thofe Cafes the Dodor took much Pains to con- 
Eder, what might be tlie mod proper Names for them. 
I am fenfible that in the Courfe of this Work there are many Errors of my 
own, and others of the Prefs, but I imagine none of them are fo very material as 
not to be correded by every common Reader in the Courfe of their Reading, fo that 
I think it not proper to trouble other People or myfelf with a long Errata,

I Have had the good Fortune fince the Publication of the third Part of this Work, 
to meet with the Green Goldfinch alive, which differs in fome Things 
from the Defcription I have given it, which inclines me to believe that Mrs. Cannon's 
Bird was a Flen, and what I have dnce feen is a Cock. They differ in the following 
Particulars : The Bill of this lad is of a fine Red, and I think rather fhorter than in 
that I have figur’d j the Rump, Coverts of the Tail^ and the Tail itfelf, are all of a 
Ene deep red Colour j the Belly is of a yellowifh Green, with fmall tranfverfe Bars 
and Spots of White a-crofs it 5 the Shoulder, or Ridge of the Wing is Green, in- 
clining to Red i in all other Points it agrees with the Bird I have defcribed in Page 
328. This Bird is the Property of the mod obliging Mrs. Clayton^ of Flower ^ in 
t^iirry\ who was pleafed to communicate feveral curious living Birds in her Poffeffion 
to me j it was brought to England from Lisbon^ and is, as I am informed, a Native
