III. Researches on myohæmatin and the histohæmatins

Abstract

This paper contains an account of observations made on the spectra of the organs and tissues of invertebrates and vertebrates, which have brought to light the presence of a series of animal colouring matter’s which had not previously been discovered. The name histohæmatins is proposed for all these colouring matters, and that of myohæmatin for the intrinsic pigment occurring in striped muscle, which belongs to the same series.
