(Ewart.) refractile lamellae, with the metabolous (anisotropous) layers of striated muscle, under a very high power. In this process of transformation, the superficial growth of the lamellae increases vertically to the fibre-axis on the one hand in a marked degree, while on the other the height of the layers also increases doubly and trebly. Along with this there are fundamental alterations in the morphological and physico-chemical reaction of the two layers, expressed above all in polarised light by the marked diminution in double refractability, which " in the metabolous layers becomes.
