The scope of the present work will allow only very brief treatment of this part of the subject.

Of or pertaining to Birds, Poultry, Etc.

There are a great variety in the amount of pneumaticity or air possessed by the skeleton of different species, but it is not necessarily determined by the flying power of the animal.
