The lower mass of musculartissue is the wall separating the two ventricles j the upper mass is the wallseparating the two auricles. On the left is seen one of the flaps of the mitralvalve. The auricular muscular tissue is seen to pass without interruption intothe ventricular wall, x 50. Fig. 2.—Section through junction of auricle and ventricle. Heart of adultrat. The auricular fibres are seen to pass without interruption into the ventri-cular wall. The magnification being greater than in Fig. 1 it is possible

The auricular fibres are seen to pass without interruption into the ventri-cular wall. The magnification being greater than in Fig. 1 it is possible tofollow individual fibres from auricle to ventricle, x 100. Fig. 3.—Section through fibrous connective-tissue ring at junction ofauricle and ventricle. Heart of adult monkey. The branched muscle-cells lyingin the fibrous tissue are well seen. Towards the auricular end one or two of theelongated fusiform cells are present, and under the microscope these may be seento be connected with the auricular muscle, x 100.
