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

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



In my lašt commuiiicatiou upon this subject (see p. 9), I stated 

 tbat I purposed adding to the list of birds dissected, and aftervrards 

 describing the air-sacs in the thoracic and abdominal eavities ; 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 disseetions * 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 aceurate con- 

 clusions. The birds since examined are the following : — 

 Kestrel. F. tinnunculus. Jay. C. glandarius. 



Kitę. F. milvus. Crow. C. corvus. 



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



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

niclus. cialis. 



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



* I have examined the skeletons of numerous birds 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.
