This conclusion has been reached as the result of studies of microscopic sections with stains, especially Best's carmine stain. When the work on which this idea was based is analyzed, however, one feels that with the inaccurate staining methods employed the question has hardly been settled.

REVIEW OF SIGNIFICANT LITERATURE

Best,¹ in 1903, published the results of a study on glycogen and described a method of staining which he considered to be fairly specific for glycogen. He found that a carmine stain of unknown chemical composition was taken up by certain granules present in the fixed tissues of the liver, of striped muscle, of tumors and . . .
