Miscellaneous. 481 



In all these works, which are of such essential value to writers 

 on ornithology, it is difficult to overestimate the labour, the accu- 

 racy, and the importance attached to their compilation. The author 

 was indefatigable in his researches, and spared no pains in searching 

 out all that had been done in ornithology from every available 

 source ; and his success was in most respects commensurate with his 

 labours. His chief fault lay not in an overweening confidence in 

 his own conclusions (for he was always most ready to avail himself 

 of any suggestions or corrections that were made to him) , but in an 

 over-sensitiveness which made him impatient of criticisms which he 

 considered carping, or of suggestions made without due considera- 

 tion on points which he had himself studied with the xxtmost 

 attention. 



In his official capacity he was always most ready to attend to and 

 assist the numerous students who visited the Museum, and to give 

 them whatever information he possessed on the subjects on which 

 they were engaged ; and many of our leading ornithologists will 

 readily admit that they owe much to his kind assistance and advice. 

 In private life he was equally kind-hearted and liberal, with some- 

 what of the same over-sensitiveness to which we have above referred 

 as distinctive of his scientific character. I3ut a truer-hearted and a 

 better friend has seldom existed ; and there are many, both in 

 public and private, who will sincerely deplore his loss. He died on 

 the 6th of May, in the 64th year of his age, leaving a blank in the 

 world of science which wiU not readily be fiUed up. He became a 

 Fellow of the Linnean Society in 1845, and of the lloyal in 1866.
