4. On the Presence or Absence of Air in the Bones of 

 Birds. By Edward Crisp, M.D. etc. 



In my last communication upon this subject (see p. 9), I stated 

 that I purposed adding to the list of birds dissected, and afterwards 

 describing the air-sacs in the thoracic and abdominal cavities ; the 

 method by which air is admitted to the hollow bones, and the flight 

 of birds in relation to these matters ; but as the communication is 

 longer than I expected, I will reserve the second part of my subject, 

 viz. the admission of air to the bones, for my next and concluding 

 paper. 



My dissections * have not been so numerous as I could have 

 wished, but the following list, in addition to that of my first com- 

 munication, will, I think, enable me to form tolerably accurate con- 

 clusions. The birds since examined are the following : — 

 Kestrel. F. tinnuneulus. Jay. C. glandarius. 



Kite. F. milvus. Crow. C. corvus. 



Common Buzzard. F. buteo. Cuckoo. C. canorus. 



Marsh Harrier. F. ceruginosus. Spotted Woodpecker. P. major. 

 American Eagle Owl. 5. Ameri- Grey Parrot. P. erythacus. 



canus. Crested Paraqueet. P. Novce 



Long-eared Owl. S. otus. Hollandice. 



Tawny Owl. S. aluco. Impeyan Pheasant. P. Impey- 



Barn Owl. S.jiammea. anus. 



Glossy Starling. Jidda nitens. Heron. A. cinerea. 

 Spotted Fly-catcher. M.yrisola. Turnstone. S. interpres. 

 Whin-chat. S. rubetra. Sarus Crane. G. Antigone. 



Wood Wren. S. sibilatrix. Bean Goose. A. seyetum. 



Willow Wren. S. trochilus. Cereopsis Goose. Cereopsis Novae 



Blue Titmouse. P. cceruleus. Hollandice. 



Marsh Titmouse. P. palustris. Eider Duck. A. mollissima. 

 Long-tailed Titmouse. P. cau- Smew. Meryus albellus. 



datus. Red-necked Grebe. P.rubricollia. 



Black-headed Bunting. E. schce- Great Northern Diver. C. gla- 



niclus. cialis. 



Canary. C. canaria. Cormorant. C. cormoranus. 



* I have examined the skeletons of numerous hirds not mentioned in the above 

 lists ; but for the sake of greater accuracy, I think it better to confine myself to 

 birds dissected soon after death.
