Le cœur mis à nu - continued...

Johann Nepomuk Czermak, a student of Purkyne, was especially eager to distribute the knowledge of experimental physiology by means of movement-images. In 1867, this later director of the physiological "spectatorium" at Leipzig (1871) gave popular lectures on physiological topics at the University of Jena. In a lecture on the heart, Czermak tried to demonstrate its rhythmic movement by using a cardioscope specifically designed for this purpose.
