PREFACE. XI 



the different Ornithological collections of his friends, independent of 

 those in his o^vn well-chosen cabinet of subjects in Natural History. 



I am under many obligations to Lord Stanley, not only for the 

 loan of many fine specimens, at various times, but also for his 

 scientific observations ; and it is well known, that his collection of 

 preserved birds is not only numerous but select. 



I have been greatly assisted in my pursuit by the inspection of 

 a large number of drawings, brought from India, by Sir J. Anstru- 

 ther, Bart, done under the eye of Dr. Buchanan ; and am also under 

 similar obligations to the last named gentleman, not only for the 

 use of his own portfolios of Ornithological drawings, but also for his 

 animadversions on the subjects therein contained. 



To the Earl of Mountnorris I am not less obliged, for assisting 

 me with the view of his numerous drawings of Indian and other 

 birds, made under his inspection. To Mr. Salt, also, many thanks 

 are due, for furnishing me with the specimens of birds, collected by 

 him during his journey into Abyssinia, among which were many 

 entirely new. 



I also feel myself most deeply indebted to Lieuten ant-General 

 Hardwicke, of the Bengal Artillery, who, with the utmost liberality, 

 entrusted me, for a long time, with his very numerous and select 

 drawings of the birds of India, where he resided many years, taken 

 under his direction, from the subjects themselves. 



The world will no doubt give me credit for mentioning two 

 British Ornithologists, now no more ; I mean William Boys, Esq. 

 of Sandwich, in Kent; and Colonel Montagu, Author of the Orni-^ 

 thological Dictionary, as I have from both of them received many 

 useful remarks and observations on many British species.
