Moreover, the sections left in glycerol solution and maintained at 0° C. can remain for more than a week without any perceptible defect and thus could be utilized for future observations. The desired region of the mounted section was projected on the screen of a microphotographic camera at a magnification of 47 X and the photographic print- ing paper exposed directly to the image. "Normal" bromide papers were found. FIGURE 1. Dorsal view of the pectoral is major muscle of the pigeon showing the hypo- thetical lines 0-120 along which the distribution of broad fibers is recorded in Figure 2. The squares A and B indicate the regions of the muscle used for studying the variation in metabolite load and the structure at different depths of the muscle. suitable. Using the sliding vernier on the stage of the microscope, continuous photographic records of the distribution of the broad fibers were made (Fig. 5). From such records by the method of random sampling, the mean value of the number of broad fibers per square mm. was determined for every mm. depth of the muscle. A survey of all the twelve regions was thus completed and a graph plotted illustrating the continuous distribution of broad fibers per square mm. at the distance of every 5 mm. along the line 0-120 (Fig. 1). The lines demarcating the areas containing 30-50. 50-70, 70-90, 90-100, 100-120 and 120-140 and 120—150 broad fibers per square mm. were, drawn. The entire procedure was.
