An account of an experiment of preserving animals alive by blowing through their lungs with bellows.

By blowing air from a bellows over the exposed lungs of a dog, Hooke proved that respiratory motion is not necessary to maintain life, but that the essential feature of respiration lies in certain blood changes in the lungs.
