title: THE APPLICATION OF TRANSMITTANCY MEASUREMENTS TO BIOCHEMISTRY.
abstract: In a very brief way I have tried to show how absorption spectra have been intimately related to the development of our knowledge of chlorophyll. One hundred years ago Stokes discovered several laws that are very applicable to-day. For apparatus he used a boarded-up window, a slit in a plank, a lens and a prism. Instead of thinking how much we have accomplished with highly refined instruments we biochemists should rather humble ourselves by thinking how little use we have made of the instruments which you have so nobly perfected.
