The crystal molecule contains 21 atoms of carbon, 28 of hydrogen, five of oxygen. It seems to have the same effect on animals as impure concentrations of the natural hormone, although more of the crystals are required...

The respiratory centre is stimulated and increased breathing enables the lungs to ventilate faster, which is of prime importance in heart failure...
