The respiratory mechanisms of birds are definitely adapted to the function of flight, as evidenced by the fact that birds which do not fly (Apteryx, Penguins) show these adaptations in a greatly reduced form.

There can be little doubt that fishes swimming rapidly do not make respiratory movements at all, but obtain the necessary ventilation of the gills simply by opening the mouth.

It is no doubt technically possible to study metabolism and respiration of fishes during swimming at a constant rate, and of certain insects and birds during flight, and to obtain information similar to that obtained on man during work on a bicycle ergometer or a treadmill.

The tremendous honour of the Nobel Prize is of the strongest incentive to me in my work, while the amount of the Prize will greatly simplify my task and provide me with much valuable help in my work.

In many cases of inflammation, the vascular changes develop slowly and long after the application of the stimulus which is responsible for the inflammatory reaction.

For a large number of problems, there will be some animal of choice, or a few such animals, on which it can be most conveniently studied.
