10H MISCELLANIES. 



tive to moth in museums, I have seen used, and have used myself with great 

 effect, the huile de petrole, put into glass vessels like shallow finger-glasses ; and 

 four or five in a case of 20 feet long, will produce so powerful an effluvium,* that 

 it is necessary to have as many watch-glasses, with small portions of musk in 

 them, to make it bearable. But this, in good air-tight cases, is of little conse- 

 quence. — Magazine of Natural History, New Series, No. IV., April, 1837. 



Instance of the Missel Thrush singing on the Wing. — Instances of this 

 bird having been known to sing while flying have from time to time been recorded. 

 The circumstance is certainly not one of common occurrence, though we have 

 noticed it more than once. A few days ago one flew from a tree close to where 

 we were standing, singing all the while, and we listened to the notes until they 

 were at length lost in the distance. We never met with a more remarkable in- 

 stance of the fact than this ; as the bird in most cases only utters its strain 

 while flying from one lofty tree to another close at hand. — Ed. 



Hawking with the Golden Eagle. — The following remarkable fact is, we 

 believe, without a precedent in the annals of hawking : — Captain Green, of 

 Buckden, in Huntingdonshire, has now in his possession a splendid specimen of 

 the Golden Eagle, which he has himself trained to take Hares and Rabbits. — 

 When the difficulty even of handling a bird of the size and strength of the 

 Golden Eagle is considered, the performance of Captain Green must be deemed 

 extraordinary. Hawks are carried on the fist of the falconer, but this would 

 be impracticable with a bird of this size and weight ; recourse was therefore 

 had to a very ingenious invention, as a substitute for the fist. — Doncaster 

 Gazette, Nov. 11, 1836. [What the "ingenious invention" was, we are not 

 informed. — Ed.] 



Entomological Bibliography. — A zealous entomologist, M. Percheron, who 

 has been much inconvenienced in his studies by having to seek for information 

 scattered through various works in the forms of monographs, treatises, memoirs, 

 notices, &c, is about to publish a catalogue raisonne of all the entomological 

 works now known, in order to facilitate the researches of future students. 



The Darklegged Warbler (Sylvia loquax, Herbert). — The first migratory 

 bird we noticed in the north of England this year, was a Darklegged Warbler. 

 We observed one individual flying briskly about a wet ditch, on the morning of 

 April 21, very lively, but apparently hungry. It first settled on the hedge above, 

 then descended upon the bank, or darted down upon a slender twig close to the 

 water, a drop of which it would occasionally sip. It was extremely tame, and 

 evidently looked upon us as friendly to the feathered race. Sometimes it would 



* This we consider a [great drawback to the introduction into common use of the huile d* 

 vetrole. — Ed.
